DAYS 1-5 (APRIL 30 – MAY 4)

We’re about to say goodbye to April and this last day of the month will feature breezy, mild, but dry conditions behind a cold front. We’ll have some clouds, both patchy mid level leftovers drifting southeastward in the air flow behind the front, and some high cloudiness fanning up in the higher level southwesterly winds over the region, so sun will not be unlimited today. High pressure builds in tonight and Thursday. Thursday’s weather will be quite nice – more sun, less wind, mild, but a cooling sea breeze near the coast. High clouds do increase again later Thursday ahead of a warm front. Our next unsettled weather stretch is poorly timed for Friday into the weekend, but there are going to be some “nicer” times embedded in that stretch – a matter of working out the details in the shorter term over the next couple days to highlight them. The best guess at this point is that warm frontal showers (and a possible thunderstorm) occur in a several hour window Friday morning, and the approach of a cold front can trigger another shower or thunderstorm later in the day from west to east. The problem: This cold front is not likely to make a clean pass through the region, but get hung up, and allow another wave of low pressure to come up along it during Saturday. Some guidance holds rainfall back until later Saturday, or at night, while other guidance brings it in more hastily. I’m leaning toward the quicker scenario for this at the moment, with occasional showers any time that day. The front should be pulled through for a cooler Sunday, but it may remain somewhat unsettled as upper level low pressure swings through the region – so I can’t leave out the shower threat that day in the current version of the forecast.

TODAY: Sun/cloud mix. Highs 70-77. Wind NW 10-20 MPH, higher gusts.

TONIGHT: Mostly clear. Lows 46-53. Wind NW 5-15 MPH.

THURSDAY: Sunny through early afternoon, then increasing high clouds. Highs 67-74, cooler coast. Wind variable up to 10 MPH with coastal sea breezes.

THURSDAY NIGHT: Becoming mostly cloudy. A few showers and a slight chance of a thunderstorm overnight. Lows 53-60. Wind SE to S up to 10 MPH.

FRIDAY: Mostly cloudy. Chance of showers, favoring early-morning and late-afternoon, including a slight chance of thunderstorms. Highs 65-72. Wind S 5-15 MPH.

FRIDAY NIGHT: Mostly cloudy. A shower possible early. Lows 51-58. Wind SW to variable 5-15 MPH.

SATURDAY: Mostly cloudy. Additional showers likely. Highs 62-69. Wind variable 5-15 MPH.

SATURDAY NIGHT: Mostly cloudy. A chance of showers. Lows 50-57. Wind variable 5-15 MPH.

SUNDAY: Variably cloudy. A chance of showers. Highs 58-65. Wind NW 5-15 MPH.

DAYS 6-10 (MAY 5-9)

There’s a lot of uncertainty in the forecast for next week. Our various sets of guidance show different details, but the general idea is the evolution of a blocking pattern. The set-up of low pressure vs. high pressure determines wet weather (and magnitude of it) vs. dry weather, air flow and temperature. Current leaning: Fair weather May 5. Unsettled with marine air flow middle of next week. Fair weather end of week.

DAYS 11-15 (MAY 10-14)

Expecting a blocking pattern to be dominant heading into mid May. Again, unsettled weather vs. fair weather TBA, but suspect as features shift slightly we’ll have a bit of both. Some recent indications of wetter weather being pushed to the south and a drier, cooler scenario for this region. Will monitor trends on reliable guidance.

DAYS 1-5 (APRIL 29 – MAY 3)

High pressure moves offshore and a southwesterly air flow increases today between it and an approaching cold front. We’ll have a warm day as a result, but the South Coast will be cooler where a southwest wind comes off the ocean water. The aforementioned cold front may trigger a rain shower tonight as it moves through the region, and this will be followed by breezy, dry and only slightly cooler weather Wednesday. High pressure builds in for Thursday – a nice day but with a cooling sea breeze near the coast. Clouds start to move in later Thursday ahead of a warm front, and a this leads to an more cloud-filled Friday sky with rain showers possible both early in the day with a warm frontal passage, and late-day with an approaching cold front. Isolated thunderstorms are possible as well. Unfortunately, the trend for Saturday as for more unsettled weather as the cold front slows down and a wave of low pressure moves up along it, producing additional rain showers.

TODAY: Mostly sunny. Highs 58-65 Cape Cod, 66-73 remainder of South Coast, 74-81 elsewhere, warmest over interior valley locations. Wind SW increasing to 10-20 MPH with gusts over 20 MPH in the afternoon.

TONIGHT: Partly cloudy. A possible rain shower overnight. Lows 52-59. Wind SW 5-15 MPH, higher gusts.

WEDNESDAY: Mostly sunny. Highs 70-77. Wind NW 10-20 MPH, higher gusts.

WEDNESDAY NIGHT: Mostly clear. Lows 46-53. Wind NW 5-15 MPH.

THURSDAY: Sunny through early afternoon, then increasing high clouds. Highs 67-74, cooler coast. Wind variable up to 10 MPH with coastal sea breezes.

THURSDAY NIGHT: Becoming mostly cloudy. A few showers and a slight chance of a thunderstorm overnight. Lows 53-60. Wind SE to S up to 10 MPH.

FRIDAY: Mostly cloudy. Chance of showers, favoring early-morning and late-afternoon, including a slight chance of thunderstorms. Highs 65-72. Wind S 5-15 MPH.

FRIDAY NIGHT: Mostly cloudy. A shower possible early. Lows 51-58. Wind SW to variable 5-15 MPH.

SATURDAY: Mostly cloudy. Additional showers likely. Highs 62-69. Wind variable 5-15 MPH.

DAYS 6-10 (MAY 4-8)

Upper level low pressure brings a cool-down and still can trigger a shower May 4. Briefly fair May 5, then additional unsettled weather possible as upper level low pressure reorganizes nearby as a blocking pattern evolves. Temperatures variable – averaging not far from normal.

DAYS 11-15 (MAY 9-13)

Continued indications of a blocking pattern with upper level low pressure in control of our weather – an unsettled pattern with near to below normal temperatures.

DAYS 1-5 (APRIL 28 – MAY 2)

High pressure brings fair, warmer weather today and we’ll be rid of yesterday’s gusty wind. Cape Cod will be coolest due to ocean’s influence. High pressure shifts offshore tonight and Tuesday. An increasing southwesterly wind will keep more of the South Coast on the cooler side, while the remainder of the region sees its warmest day of the next five. Low pressure scooting quickly across southeastern Canada will drag a cold front quickly through the region, producing no more than a couple rain showers late Tuesday night / early Wednesday morning, and bringing a wind shift and a very slight temperature decline for Wednesday’s daytime highs. High pressure builds in Thursday with a day very similar to what we have today. You’ll see clouds on the increase later Thursday, however, in advance of a warm front which will move into and across the region through Friday, bringing unsettled weather – mild air, higher humidity, and a shower / thunderstorm threat to end the week.

TODAY: Mostly sunny. Highs 60-67 Cape Cod, 68-75 elsewhere. Wind NW 5-15 MPH, diminishing late.

TONIGHT: Clear. Lows 48-55, a few cooler pockets over interior valleys. Wind W under 10 MPH.

TUESDAY: Mostly sunny. Highs 58-65 Cape Cod, 66-73 remainder of South Coast, 74-81 elsewhere, warmest over interior valley locations. Wind SW increasing to 10-20 MPH with gusts over 20 MPH in the afternoon.

TUESDAY NIGHT: Partly cloudy. A possible rain shower overnight. Lows 52-59. Wind SW 5-15 MPH, higher gusts.

WEDNESDAY: Partly cloudy with a possible rain shower early then mostly sunny. Highs 70-77. Wind NW 10-20 MPH, higher gusts.

WEDNESDAY NIGHT: Mostly clear. Lows 46-53. Wind NW 5-15 MPH.

THURSDAY: Sunny through early afternoon, then increasing high clouds. Highs 67-74, cooler coast. Wind variable up to 10 MPH with coastal sea breezes.

THURSDAY NIGHT: Becoming mostly cloudy. A few showers and a slight chance of a thunderstorm overnight. Lows 53-60. Wind SE to S up to 10 MPH.

FRIDAY: Mostly cloudy. Chance of showers. Slight chance of thunderstorms. Highs 65-72. Wind S 5-15 MPH.

DAYS 6-10 (MAY 3-7)

Pattern turns unsettled as upper level low pressure evolves over the US Northeast. Initially, low pressure passes north of the region with a trough and cold front bringing a couple rounds of showers and possible thunderstorms to start the weekend on May 3, and an upper cool pool can trigger a shower on May 4. A brief fair weather interlude about May 5 is likely followed by additional unsettled weather later in the period.

DAYS 11-15 (MAY 8-12)

Strong indications of a blocking pattern with upper level low pressure in control of our weather – being an unsettled and near to below normal temperature pattern.

DAYS 1-5 (APRIL 27 – MAY 1)

While yesterday’s showery, humid weather have been pushed out by a cold front, we don’t get to enjoy a sunny, pleasant day today and here’s why. A pool of very cold air aloft will be crossing the region during the day today with upper level low pressure. This counterclockwise spin in the atmosphere and very cold air above relatively warmer air near the surface creates an unstable atmosphere, and even if there is sun (which some areas are seeing – or saw – early on in the day, clouds develop and fill in the sky and dominate, and there will be nothing more than limited breaks of sun for the balance of the day. The extensiveness of the cloud cover will limit the development of convective showers, but a few already exist with help from the mountains to our north, so I cannot rule out a passing rain shower at any point, starting right away in southern NH and far northern MA, and occurring anywhere later on, but again favoring those northern locations. For the most part, despite the extensive cloud cover, it will be rain-free. Additionally, if you have outdoor plans, you’ll have to contend with cool air (highs in the 50s), and blustery conditions (wind gusts above 20 MPH). Tonight, the upper low exits and clearing takes place. High pressure builds in Monday, then slides offshore Tuesday. These days will be fair with a warm-up. Early Wednesday morning, low pressure scoots rapidly across southeastern Canada and drags a quick-moving cold front through the region. Aside from a possible brief rain shower, this front will move through mainly rain-free, just featuring a wind shift and an ever-so-slight cool-down for Wednesday – nearly unnoticeable, along with a gusty breeze. High pressure then builds in for a lovely opening day of May on Thursday.

TODAY: Early sun mostly Boston area south, otherwise mostly cloudy. Isolated rain showers, favoring areas north of I-90. Highs 52-59. Wind NW 10-20 MPH, higher gusts.

SUNDAY NIGHT: Clearing. Lows 35-42. Wind NW 5-15 MPH.

MONDAY: Mostly sunny. Highs 63-70. Wind NW 5-15 MPH.

MONDAY NIGHT: Mostly clear. Lows 50-57. Wind W 5-15 MPH.

TUESDAY: Mostly sunny. Highs 70-77 except cooler South Coast. Wind SW 5-15 MPH, higher gusts.

TUESDAY NIGHT: Partly cloudy. A possible rain shower overnight. Lows 52-59. Wind SW 5-15 MPH, higher gusts.

WEDNESDAY: Partly cloudy. A possible rain shower early. Highs 68-75. Wind NW 10-20 MPH, higher gusts.

WEDNESDAY NIGHT: Mostly clear. Lows 46-53. Wind NW 5-15 MPH.

THURSDAY: Sunny. Highs 67-74, cooler coast. Wind variable up to 10 MPH with coastal sea breezes.

DAYS 6-10 (MAY 2-6)

Pattern turns unsettled as upper level low pressure evolves over the US Northeast. As far as day-to-day details, it’s too far in the future for those, but May 2, part of May 3, and May 6 are the most likely days to have wet weather chances for our region. Temperatures variable with an overall cooling trend indicated.

DAYS 11-15 (MAY 7-11)

A blocking pattern holds upper level low pressure over the Northeast much of this period with additional unsettled weather and below normal temperatures.

DAYS 1-5 (APRIL 26-30)

Down the home stretch of April 2025 we go! And it starts out with an unsettled weekend, but today will clearly be the wetter of the two days, as widespread rain showers are ours for the morning hours. While there are lulls, scattered rain showers and even a few downpours will be around this afternoon and evening until a cold front pushes through the region, at which time the threat will end. Sunday, upper level low pressure has to move across the region, with lots of cold air aloft. Any meaningful sun will be confined to eastern areas early in the day, otherwise the sky will be dominated by cold air cumulus / stratocumulus, another fairly typical springtime thing here. We’ll have a breezy, cool, and mainly dry day, but I cannot rule out some passing showers, triggered by the cold air aloft, particularly during the afternoon hours. The cold pool finally exits at night. This sets up fair weather and a warm-up early next week as high pressure moves in Monday, then slides off the coast Tuesday. A quick-moving cold front may deliver a rain shower early Wednesday before we get back to dry and breezy weather.

TODAY: Cloudy with widespread rain showers and patchy fog morning. Mostly cloudy with scattered rain showers afternoon. Highs 61-68, except 53-60 South Coast (coolest Cape Cod). Wind S to SW 10-20 MPH.

TONIGHT: Mostly cloudy with additional rain showers possible early. Lows 45-52. Wind shifting to NW 5-15 MPH with higher gusts.

SUNDAY: Partly sunny early, then mostly cloudy. A passing rain shower possible. Highs 53-60. Wind NW 10-20 MPH with higher gusts.

SUNDAY NIGHT: Clearing. Lows 35-42. Wind NW 5-15 MPH.

MONDAY: Mostly sunny. Highs 63-70. Wind NW 5-15 MPH.

MONDAY NIGHT: Mostly clear. Lows 50-57. Wind W 5-15 MPH.

TUESDAY: Mostly sunny. Highs 70-77 except cooler South Coast. Wind SW 5-15 MPH, higher gusts.

TUESDAY NIGHT: Partly cloudy. A possible rain shower overnight. Lows 52-59. Wind SW 5-15 MPH, higher gusts.

WEDNESDAY: Partly cloudy. A possible rain shower early. Highs 68-75. Wind NW 10-20 MPH, higher gusts.

DAYS 6-10 (MAY 1-5)

Fair weather probability highest May 1 & 5, book-ending an unsettled potential in the May 2-4 window. Details not possible this far in advance. Temperatures variable – averaging near normal.

DAYS 11-15 (MAY 6-10)

Spring blocking pattern. Additional unsettled weather. Variable temperatures – no extremes indicated.

DAYS 1-5 (APRIL 25-29)

The spring of 2025 rolls on and is starting to gain a bit of a reputation for being “not that nice”. Now this is only partially true, as it’s a matter of perspective and what amount of time you’re looking at. March was a rather dry and mild month, but with many people still in “winter mode” they don’t partake in the springtime activities outside, which explode in popularity in the month of April, especially around here when we approach and reach the weekend that includes Patriots Day (just this past week). But even before that, the “hibernating” folks come out for their first walks, yard work, etc., and like to be greeted with some good weather. And don’t get me wrong, we’ve had some nice days, but the timing of the unsettled days has been including at least parts of weekends much of this month, and the final weekend of April 2025 is going to be no different. Ouch! It’s not a total wash-out, but the weekend is not going to get high marks from the average person. How will it unfold? First, we have a warm front pushing through the region now, and abundant clouds are in the sky. This will be the case much of today, but there will be some intervals of sunshine as well. I can’t rule out a few rain showers migrating across the region, particularly over northern MA and southern NH. The frontal boundary also comes to a halt and may slip back to the south as a “temporary” back-door cold front, shutting the NH Seacoast and northeastern MA out of the warmer air with a light northeasterly air flow. Meanwhile, the south to southwest wind that overtakes the remainder of the region is naturally a cooler one for the South Coast and Cape Cod at this time of year, so they’ll be in much the same boat, temperature-wise, as southeastern NH and northeastern MA is today. During the weekend, we start with a fairly mild but unsettled Saturday as a trough and cold front have to move through, and won’t be in a grand hurry. Timing-wise, it looks like the most widespread rain showers will take place during the morning, with more “off” than “on” during the afternoon and evening, but we still have to watch for a couple batches of showers until the front passes through, and that doesn’t likely happen until the evening hours. So that means we’re in the clear for Sunday, right? Not so fast. Yup, we’ll be behind the cold front, and Sunday will certainly be a cool day regionwide, but many would take that in trade-off for sunshine. However, upper level low pressure has to move across the area. And those contain plenty of cold air aloft. If you get any sun, you pop abundant diurnal clouds, in addition to any existing cloud cover with the upper low to begin with, so I’m looking for very limited sunshine on Sunday, and also cannot rule out a passing rain shower. At least the rainfall threat will be rather isolated, and any that do occur would be rather brief, in comparison to Saturday’s showers. So if you have to pick a day for the better of the 2 for outside activity, it’s Sunday, that is if you can handle the gusty breeze we’ll have, making the 50s feel more like 40s at times. Sorry! 😉 But hey guess what? High pressure builds in just as the weekend wraps up, and fair weather and a warming trend will be with us as many head back to work (and back to school after vacation). Yep. Timing is everything! 😉

TODAY: Lots of clouds / limited sun. Maybe a rain shower, favoring areas north of I-90 and particularly northern MA and southern NH. Highs 55-62 South Coast as well as NH Seacoast to Cape Ann MA, 63-70 elsewhere (can break 70 inland areas with enough sun). Wind S to SW 5-15 MPH except NE up to 10 MPH southeastern NH and northeastern MA.

TONIGHT: Mostly cloudy. Patchy fog. An isolated rain shower evening. more widespread rain showers arrive west to east toward dawn. Lows 50-57. Wind S 5-15 MPH.

SATURDAY: Cloudy with widespread rain showers and patchy fog morning. Mostly cloudy with scattered rain showers afternoon. Highs 61-68, except 53-60 South Coast (coolest Cape Cod). Wind S to SW 10-20 MPH.

SATURDAY NIGHT: Mostly cloudy with additional rain showers possible early. Lows 45-52. Wind shifting to NW 5-15 MPH with higher gusts.

SUNDAY: Partly sunny early, then mostly cloudy. A passing rain shower possible. Highs 53-60. Wind NW 10-20 MPH with higher gusts.

SUNDAY NIGHT: Clearing. Lows 35-42. Wind NW 5-15 MPH.

MONDAY: Mostly sunny. Highs 63-70. Wind NW 5-15 MPH.

MONDAY NIGHT: Mostly clear. Lows 50-57. Wind W 5-15 MPH.

TUESDAY: Mostly sunny. Highs 70-77 except cooler South Coast. Wind SW 5-15 MPH.

DAYS 6-10 (APRIL 30 – MAY 4)

Warm April 30 but chance of a shower as a cold front approaches / passes. Fair, cooler May 1. Unsettled weather threat returns late May 2 into the first weekend of May – details TBD.

DAYS 11-15 (MAY 5-9)

Spring blocking pattern. Additional unsettled weather. Variable temperatures – no extremes indicated.

DAYS 1-5 (APRIL 24-28)

High pressure hangs on with fair weather across the region today. Temperatures will be fun to track for a while, starting with chilly morning lows followed by a quick rise that is thwarted by a coastal sea breeze, setting up a significant contrast in high temps between the coast and inland. A warm front will cross the region tonight and early Friday, perhaps with brief light rain for southern NH / northern MA though most areas stay dry. This front may try to slip back south southwestward as a back-door cold front into southeastern NH and possibly northeastern MA during Friday, so the temperature forecast is a bit tricky, and there may even be an additional rain shower or two near that boundary. A more significant warm sector push takes place Saturday with a southwesterly air flow across the region, but accompanied by lots of clouds and at least a couple rounds of rain showers. Still working on the timing / coverage forecast details for this, but for now just plan on an unsettled day in which it can rain at any time. Behind a cold front comes blustery, cooler weather for Sunday, with a sun/cloud mix as some cold air aloft causes some instability. There may be a diurnal rain shower or two (maybe some graupel if heavy enough?) across parts of the region, but overall look for a dry day. High pressure dominates Monday with fair weather, a chilly start, then a nice temperature recovery.

TODAY: Sunny to partly cloudy. Highs ranging from 50-57 immediate coast (coolest Cape Cod) to 68-75 inland (warmest interior valleys). Wind variable up to 10 MPH with coastal sea breezes up to 15 MPH.

TONIGHT: Variably cloudy with brief light rain possible northern MA and southern NH. Lows 45-52 evening, with a slow rise overnight. Wind SE shifting to SW up to 10 MPH.

FRIDAY: Sun/cloud mix. Highs ranging from 55-62 South Coast to 68-75 inland areas west of the I-95 belt, but may turn cooler southeastern NH and northeastern MA. Wind SW 5-15 MPH except possibly NE for a time in southeastern NH and northeastern MA.

FRIDAY NIGHT: Variably cloudy. Patchy fog. Lows 50-57. Wind S 5-15 MPH.

SATURDAY: Variably cloudy with rain showers likely. Highs 61-68, cooler Cape Cod. Wind SW 10-20 MPH.

SATURDAY NIGHT: Clearing. Lows 45-52. Wind W 5-15 MPH.

SUNDAY: Sun/cloud mix. A brief shower of rain (low chance of graupel mix) in the afternoon, favoring southern NH / northeastern MA. Highs 56-63. Wind NW 10-20 MPH, higher gusts.

SUNDAY NIGHT: Clearing. Lows 35-42. Wind NW 5-15 MPH.

MONDAY: Mostly sunny. Highs 63-70. Wind NW 5-15 MPH.

DAYS 6-10 (APRIL 29 – MAY 3)

Warmer weather April 29-30 with fair weather April 29 then a chance of a shower or thunderstorm with a cold front approaching during April 30. Watching for cooler and additional unsettled weather in the early days of May, but uncertain as to how the pattern is going to set-up during thiss period.

DAYS 11-15 (MAY 4-8)

Continued indications of blocking evolving with increase unsettled weather chances and variable temperatures.

DAYS 1-5 (APRIL 23-27)

Mother Nature has been giving us example of “classic spring scenarios” recently, and today / tonight / tomorrow will fit that category as well. We start today with some filtered sun as a canopy of high clouds, the one that provided a beautiful sunset yesterday for many areas, continues to slide across the sky, eventually shifting offshore. Meanwhile, there are some coastal areas, particularly Outer Cape Cod, that can’t see this at all early this morning under a blanket of marine stratus. A wind shift to the northwest should push this offshore as well over the next couple hours, and that northwesterly air flow will also limit how much sea breeze takes place today, but ultimately many coastal areas do end up cooler than inland this afternoon with a light sea breeze. Tonight, high pressure settles right over the region, and with a clear sky, this is the perfect set-up for radiational cooling, when the warmth of the day radiates quickly away from the surface and we chill down quickly. Under this set-up, inland valley locations end up the coldest, so some of the areas that end up the warmest this afternoon will end up the coldest tomorrow morning – classic spring set-up. Thursday, with high pressure still over the region, the light wind will allow for a more prominent sea breeze in the coastal plain, setting up a larger temperature contrast between the coast and interior for high temps. Additionally, with inland areas being the warmest in the afternoon after being the coldest in the morning, we’ll get an example of the large temperature “diurnals” (difference between low temp and high temp) that can occur in the spring. So you see, there can be a lot of weather to talk about even when you have high pressure and fair weather dominating. Moving onward, we’ll see an increase in high and middle clouds later Thursday ahead of a warm front. This front may produce some scattered rain showers across southern NH and perhaps far northern MA at some point Thursday night, and will lead a warmer air mass on a southwesterly air flow into the region on Friday, but of course this air flow is a cooler one for the South Coast, particularly Cape Cod. Additionally, getting the warm southwesterly air flow into all areas for the day is not a complete lock. All it takes is the tiniest wave of low pressure to form on that front just to the north and it gets pulled back, with the help of marine air, southwestward as a back-door cold front. This is a possibility especially Boston northward on Friday, so something to watch for. Looking ahead to the weekend, the next round of unsettled weather is due on Saturday as a cold front sweeps across the region, trailing form low pressure passing to our north. I’m not expecting a wash-out of a day, but as it looks now, I think two rounds of showers will occur, one with a pre-frontal trough, the other with the cold front itself. Timing and details will be fine-tuned as we get closer. Sunday will be a breezy, cooler, dry day with a sun/cloud mix behind the front.

TODAY: Limited sun at first Cape Cod / filtered sun at first elsewhere. Brighter sun all areas midday on. Highs 57-64 I-95 eastward / south of I-90, 65-72 elsewhere. Wind NW up to 10 MPH with light coastal sea breezes.

TONIGHT: Mostly clear. Lows 33-40 interior locations, coldest in valley areas, and 40-47 coastal plain, warmest in Boston. Wind calm.

THURSDAY: Sunny morning. Partly cloudy afternoon. Highs 57-64, 65-72 inland, but a more notable temperature fall in coastal areas after midday. Wind variable up to 10 MPH with coastal sea breezes up to 15 MPH.

THURSDAY NIGHT: Variably cloudy with brief light rain possible northern MA and southern NH. Lows 45-52 evening, with a slow rise overnight. Wind SE shifting to SW up to 10 MPH.

FRIDAY: Sun/cloud mix. Highs ranging from 55-62 South Coast to 68-75 inland areas west of the I-95 belt. Wind SW 5-15 MPH.

FRIDAY NIGHT: Variably cloudy. Patchy fog. Lows 50-57. Wind SW 5-15 MPH.

SATURDAY: Variably cloudy with rain showers likely. Highs 60-67, cooler Cape Cod. Wind SW 10-20 MPH, shifting to W from west to east by late-day.

SATURDAY NIGHT: Clearing. Lows 45-52. Wind W 5-15 MPH.

SUNDAY: Sun/cloud mix. Highs 58-65. Wind NW 10-20 MPH.

DAYS 6-10 (APRIL 28 – MAY 2)

Dry with a warming trend early in the period. A more unsettled pattern arrives to end April and start May with some wet weather possible.

DAYS 11-15 (MAY 3-7)

Continued indications of blocking evolving with increase unsettled weather chances and variable temperatures with an overall cooling trend.

DAYS 1-5 (APRIL 22-26)

Today’s weather will feature improvement and a nice warm up as we rid ourselves of clouds (and very early morning showers in far eastern areas). A cold front comes through with little fanfare other than a wind shift and lowering dew points, but this allows for the warming as the air moves down off the hills and mountains and dries out, which results in warming. High pressure builds toward the region Wednesday with mild weather and a land breeze, but the high pressure area moves over the region Wednesday night and Thursday with lighter winds. This allows for a coastal sea breeze and a larger temperature contrast between the coast and inland areas on Thursday. Additionally, some clouds move in Thursday ahead of a warm front. At worst, this front can bring some brief light rainfall to northern MA and southern NH late Thursday or Thursday night, before we find ourselves in the warm sector Friday with fair weather and above normal temperatures. However, our next trough and low pressure system and its accompanying cold front will move toward the region Friday night and Saturday with some unsettled weather. What’s left to figure out is timing and how long the rain threat will last, but for now plan on an unsettled start to the final weekend of April.

TODAY: Cloudy start with areas of fog as any lingering rain showers exit. Clouds give way to sun mid morning on from west to east, but still some passing clouds and only the slightest risk of a quick-hitting rain shower. Highs 55-62 Cape Cod, 63-70 other areas south of I-90, 70-77 I-90 northward. Wind variable to S up to 10 MPH, becoming SW to W 5-15 MPH.

TONIGHT: Partly cloudy early, then clear. Lows 46-53. Wind W to NW 5-15 MPH.

WEDNESDAY: Mostly sunny. Highs 65-72, except 58-65 Cape Ann and outer Cape Cod. Wind NW 5-15 MPH.

WEDNESDAY NIGHT: Mostly clear. Lows 38-45. Wind calm.

THURSDAY: Sun gives way to clouds. Highs 56-63 coast, 63-70 inland. Wind variable up to 10 MPH with coastal sea breezes.

THURSDAY NIGHT: Mostly cloudy with brief light rain possible evening. Partly cloudy overnight. Lows 42-49. Wind SE under 10 MPH.

FRIDAY: Sun/cloud mix. Highs 58-65 South Coast, 66-73 elsewhere. Wind SW 5-15 MPH.

FRIDAY NIGHT: Mostly cloudy. Rain showers arrive. Patchy fog overnight. Lows 50-57. Wind SW 5-15 MPH.

SATURDAY: Mostly cloudy with rain showers likely, but may be most numerous early with a drying trend after. Highs 58-65. Wind SW to variable 5-15 MPH.

DAYS 6-10 (APRIL 27 – MAY 1)

Dry weather April 27-29 with a cooler start then a warming trend. Frontal system may bring rain showers April 30 and/or May 1.

DAYS 11-15 (MAY 2-6)

Trends indicate some blocking evolving with increase unsettled weather chances and variable temperatures with an overall cooling trend.

DAYS 1-5 (APRIL 21-25)

An area of high pressure provides dry weather for Patriots Day today. Rain-free conditions will grace the only morning first pitch of a MLB game this season at Fenway Park and the running of the Boston Marathon along the route from Hopkinton to Boston. While our winds will be much lighter than yesterday, the direction of that wind will play a role in temperatures along the route. As we warm from the 40s toward 60 diurnally, the temperature rise will be thwarted by a sea breeze along the coast, including into the marathon finish area. The temperature rise will stop somewhere in the 50s in the sea breeze areas while it reaches or breaks 60 over inland areas, but by then most of (if not all of) the runners will have left that area. Some rain showers associated with a warm front moving into the region will hold off until this evening, so we get through all the daytime activities rain-free. Tuesday, will feature mild weather and there is only the chance of a rain shower first thing in the morning and again sometime later in the day as a cold front crosses the region. High pressure builds in with fair, seasonable weather at midweek. While a northwesterly air flow dominates on Wednesday, the high pressure area over the region Thursday will allow a sea breeze resulting in a larger temperature contrast across the region. High pressure moves offshore Friday. A warm front scoots through early in the day when some thicker clouds may be around, but for the most part we’ll have a sun/cloud mix and above normal temperature on that day.

TODAY: High clouds filter the sun much of the day, then thicken up later. Highs 55-62, coolest coast. Wind NW up to 10 MPH becoming variable with developing sea breezes.

TONIGHT: Mostly cloudy. A brief period of light rain possible evening. Chance of rain showers overnight. Lows 48-55. Wind SE up to 10 MPH.

TUESDAY: Mostly cloudy with a chance of rain showers eastern areas early. Otherwise, partly sunny. Chance of a rain shower late in the day. Highs 57-64 South Coast to MA South Shore, 65-72 elsewhere. Wind S to SW 5-15 MPH.

TUESDAY NIGHT: Clearing. Lows 46-53. Wind NW 5-15 MPH.

WEDNESDAY: Mostly sunny. Highs 62-69. Wind NW 5-15 MPH.

WEDNESDAY NIGHT: Mostly clear. Lows 38-45. Wind calm.

THURSDAY: Mostly sunny. Highs 56-63 coast, 63-70 inland. Wind variable up to 10 MPH with coastal sea breezes.

THURSDAY NIGHT: Increasing clouds. Lows 42-49. Wind SE under 10 MPH.

FRIDAY: Cloudy early, then a sun/cloud mix. Highs 58-65 South Coast, 66-73 elsewhere. Wind SW 5-15 MPH.

DAYS 6-10 (APRIL 26-30)

A cold front moves through with a period of rain showers at some point April 26, otherwise the balance of the final weekend of April looks dry and cooler. The last few days of April look mainly fair with a milder trend.

DAYS 11-15 (MAY 1-5)

Trends indicate some blocking evolving with increase unsettled weather chances and variable temperatures with an overall cooling trend.

DAYS 1-5 (APRIL 20-24)

Happy Easter to those celebrating today! If you have outside plans, while it will be a dry and mild day, there will be a gusty wind. The sun will share the sky with passing fair-weather clouds. These may become abundant for an hour or two this afternoon at some point, depending upon your location. But overall, if you can handle the breezy / windy conditions, it will be a pretty nice April day. One negative, fire danger will be elevated. High pressure builds over the region tonight into Monday, easing the wind. This will make a sea breeze likely on Monday. While the region is cooler overall, the coast will be coolest. Expect dry weather through the day – including for the Red Sox early start and the Boston Marathon. A warm front will bring the chance of a little rainfall Monday evening, and low pressure passing to our north will drag a cold front across the region Tuesday, with a few rain showers in the region. Fair, slightly cooler weather is expected for midweek, as high pressure builds in.

TODAY: Sun and passing clouds. Highs 58-65. Wind NW 10-20 MPH.

TONIGHT: Mostly clear. Lows 38-45. Wind NW 5-15 MPH.

MONDAY: Mostly sunny through midday, then some increase in cloudiness. Highs 55-62, coolest coast. Wind NW up to 10 MPH becoming variable with coastal sea breezes developing.

MONDAY NIGHT: Mostly cloudy. A brief period of light rain possible evening. Chance of rain showers toward dawn. Lows 48-55. Wind SE up to 10 MPH.

TUESDAY: Mostly cloudy with a chance of rain showers until midday. Partly to mostly sunny thereafter. Highs 65-72. Wind SW 5-15 MPH shifting to NW, a few higher gusts possible.

TUESDAY NIGHT: Clear. Lows 46-53. Wind NW 5-15 MPH.

WEDNESDAY: Mostly sunny. Highs 62-69. Wind NW 5-15 MPH.

WEDNESDAY NIGHT: Mostly clear. Lows 43-50. Wind calm.

THURSDAY: Mostly sunny. Highs 62-69, except cooler along the coast. Wind variable up to 10 MPH with coastal sea breezes.

DAYS 6-10 (APRIL 25-29)

Progressive spring pattern. Warm front / cold front combo with low pressure passing to north can bring brief rain shower episodes April 25-26. Fair weather follows as high pressure builds in. Temperatures variable, coolest mid period, warmer end of period.

DAYS 11-15 (APRIL 30 – MAY 4)

Trend toward more blocking in the pattern. Initially a progressive system brings a shower threat early period. Unsettled weather may return end of period.

DAYS 1-5 (APRIL 19-23)

A healthy southwesterly air flow will deliver a summer preview to our region today with warm air dominating. The exception, of course, will be where the wind comes off ocean water south of New England, keeping the South Coast and southeastern MA considerably cooler – typical for April. We’ll not have full sunshine all day, so this will knock a little bit off the high temperature potential, but it won’t prevent it from getting really warm (some 80+ potential) away from the ocean’s influence. I’m only looking for the potential of a passing shower and very slight thunderstorm risk, especially north of I-90, during this evening, as a cold front moves through. This will set up a fair, cooler (but still mild), Easter Sunday with an active breeze but plenty of sunshine. High pressure builds over the region Sunday night and holds into Patriots Day – Monday – with fair and cooler weather. Coastal areas end up coolest on Monday due to sea breeze development. Additionally, some limiting of the sun will occur due to high clouds advancing ahead of an approaching warm front. This front will bring the chance of brief light rain to parts of the region Monday night, before a cold front trailing from low pressure passing to the north brings a rain shower chance during the first 12 hours of Tuesday. This exits Tuesday afternoon and we then have high pressure building toward the region with more fair weather through Wednesday, which will be a bit cooler than Tuesday.

TODAY: Variably cloudy. Highs 50-57 Islands and Outer Cape Cod, 58-65 South Coast to MA South Shore – coolest former and mildest latter, 66-73 just inland from South Coast and MA South Shore as well as Cape Ann of MA, 74-81 elsewhere with isolated 82+ readings possible in interior valley areas. Wind SW increasing to 10-20 MPH, a few higher gusts.

TONIGHT: Variably cloudy this evening with a potential passing shower and slight chance of a thunderstorm, mainly north of I-90. Clear overnight. Lows 47-54. Wind shifting to NW 5-15 MPH, a few higher gusts.

SUNDAY: Sun and passing clouds. Highs 58-65. Wind NW 10-20 MPH.

SUNDAY NIGHT: Mostly clear. Lows 38-45. Wind NW 5-15 MPH.

MONDAY: Mostly sunny through midday, then some increase in cloudiness. Highs 55-62, coolest coast. Wind NW up to 10 MPH becoming variable with coastal sea breezes developing.

MONDAY NIGHT: Mostly cloudy. A brief period of light rain possible evening. Chance of rain showers toward dawn. Lows 48-55. Wind SE up to 10 MPH.

TUESDAY: Mostly cloudy with a chance of rain showers through midday. Partly to mostly sunny thereafter. Highs 65-72. Wind SW 5-15 MPH shifting to NW, a few higher gusts possible.

TUESDAY NIGHT: Clear. Lows 46-53. Wind NW 5-15 MPH.

WEDNESDAY: Mostly sunny. Highs 62-69. Wind NW 5-15 MPH.

DAYS 6-10 (APRIL 24-28)

Unsettled weather chances later April 24 to early April 25, briefly April 26. Overall trend is a little drier for this period with somewhat variable temperatures but no extremes.

DAYS 11-15 (APRIL 29 – MAY 3)

Fairly typical spring look to the pattern. Chilly to the north in eastern Canada, a warmer Southeast US, and our area in between with a couple unsettled weather chances and variable temperatures.

DAYS 1-5 (APRIL 18-22)

High pressure slides offshore today as clouds increase ahead of a warm front. This warm front, extending from low pressure destined to pass to our north early this weekend, may produce a brief episode of light rainfall tonight, especially in southern NH and northern MA. While clouds linger Saturday morning, we’ll eventually see more sun develop and a preview of summer as it becomes the warmest day of the year-to-date. But not-so-fast along the South Coast of course where a southwesterly wind comes off much cooler ocean water, and those areas will not share in the summer feel that other areas do. A rain shower may accompany a cold front as it goes by Saturday night, and Sunday (Easter for those celebrating) will be a fair, breezy, and less-warm but still-mild day. High pressure will build over the region slackening the wind by late in the day and this high will do its best to hold on for fair weather for the Patriots Day Red Sox game and Boston Marathon on Monday, but by day’s end clouds will re-take the sky and we’ll have our next threat of rain showers. Unsettled weather will be with us into Tuesday as low pressure crosses the region. A redevelopment of this system may enhance rainfall somewhat – but those details are still to be worked out. Improvement should take place later Tuesday assuming the timing of the system is as currently expected.

TODAY: Sunshine filtered to dimmed to blotted out by increasing clouds. Highs 55-60 coast, 60-65 inland. Wind SE up to 10 MPH.

TONIGHT: Mostly cloudy. A brief period of light rain possible, favoring areas north of I-90. Lows 46-53 evening, then slowly warming overnight. Wind SE up to 10 MPH shifting to SW 5-15 MPH.

SATURDAY: Mostly cloudy morning. Mostly sunny afternoon. Highs range widely from 58-65 South Coast (even cooler Outer Cape Cod / Islands) to 75-82 interior locations. Wind SW 10-20 MPH, higher gusts.

SATURDAY NIGHT: Variably cloudy. A brief passing rain shower possible. Lows 46-53. Wind SW 5-15 MPH with higher gusts, shifting to NW.

SUNDAY: Sun and passing clouds. Highs 58-65. Wind NW 10-20 MPH.

SUNDAY NIGHT: Partly cloudy. Lows 38-45. Wind NW 5-15 MPH.

MONDAY: Partly sunny. Highs 55-62, coolest coast. Wind NW up to 10 MPH becoming variable with coastal sea breezes developing.

MONDAY NIGHT: Mostly cloudy with a good chance of rain showers. Lows 48-55. Wind SE up to 10 MPH.

TUESDAY: Mostly cloudy with a chance of showers and a period of steadier rain possible, ending later with breaking clouds and partial clearing. Highs 57-64. Wind variable 5-15 MPH becoming W late.

DAYS 6-10 (APRIL 23-27)

Unsettled weather chances April 24 to early April 25, April 26 to early April 27. Unclear on the details of either of these threats at this point. Temperatures variable, averaging out near normal.

DAYS 11-15 (APRIL 28 – MAY 2)

No changes to this outlook. Battle zone pattern between a chilly eastern Canada and warm US Southeast. Additional unsettled weather and variable temperatures.

DAYS 1-5 (APRIL 17-21)

A cool northwesterly air flow continues today between low pressure in Atlantic Canada and high pressure to our southwest. We will have considerably more sunshine than yesterday and a less gusty wind, making it feel more pleasant despite the “below normal” temperature readings. Friday, look for more cloud cover and perhaps a quick hit of light rain, mainly northern portions of our region, as a warm front approaches. Another mid level moisture surge can bring an additional batch of rain showers Friday evening / night as the warm front goes by, and then we enter the warm sector of low pressure passing to our north on Saturday. This will easily be the warmest day of the spring so far across the region, but there will be a cooling influence along the South Coast where a southwesterly air flow comes off the ocean water to the south of New England. A cold front trailing from the passing low pressure system will move through in the evening with perhaps a passing rain shower, but there does not appear to be a lot of support for much in the way of rainfall. Sunday (Easter for those celebrating) will be a fair, breezy and slightly cooler day with a northwesterly air flow behind the cold front. High pressure builds toward and eventually across the region during Monday (Patriots Day). Dry weather will prevail for the Red Sox traditional home game with late morning first pitch, and for the Boston Marathon. We will see increasing clouds ahead of the next low pressure system, but it looks like any threat of rainfall will hold off until Monday night. That day will be a little cooler than Sunday with a slightly cooler air mass in place, enhanced in coastal areas by the development of a sea breeze during the day.

TODAY: Mostly sunny. Highs 52-59. Wind NW 5-15 MPH, diminishing.

TONIGHT: Clear. Lows 32-39. Wind variable under 10 MPH.

FRIDAY: Variably cloudy. A brief period of light rain possible north of I-90. Highs 53-60, coolest coast. Wind SE up to 10 MPH.

FRIDAY NIGHT: Mostly cloudy. A chance of passing rain showers evening. Lows 45-52 evening then a slow temperature rise overnight. Wind SE shifting to SW 5-15 MPH.

SATURDAY: A sun/cloud mix. A possible late day rain shower favoring areas north and west of Boston. Highs ranging widely from 55-62 South Coast to 73-80 interior valleys and typical warm spots. Wind SW 10-20 MPH, gusty.

SATURDAY NIGHT: Variably cloudy. A shower possible early, favoring Boston south. Lows 45-52. Wind shifting to NW 5-15 MPH, higher gusts.

SUNDAY: Sun/cloud mix. Highs 58-65. Wind NW 10-20 MPH.

SUNDAY NIGHT: Partly cloudy. Lows 38-45. Wind NW 5-15 MPH.

MONDAY: Partly sunny. Highs 55-62, coolest coast. Wind NW up to 10 MPH becoming variable with coastal sea breezes developing.

DAYS 6-10 (APRIL 22-26)

Passing low pressure systems bring some rainfall chances about every other day during this unsettled stretch with variable but overall near normal temperatures. Future fine-tuning to come.

DAYS 11-15 (APRIL 27 – MAY 1)

Typical springtime pattern of a warm US Southeast and a chilly eastern Canada with our region in a mid-ground “battle zone” of potential unsettled weather and variable temperatures, none of which can be pin-pointed this far in advance.

DAYS 1-5 (APRIL 16-20)

A little technical issue (computer related) results in a short discussion today, although not really anything has changed since yesterday’s outlook anyway. Today we’re in a healthy northwesterly air flow behind low pressure, with blustery and chilly conditions and a mix of sun and clouds – the latter may dominate for several hours in any location. A cold night tonight as high pressure builds toward the region and winds slacken but remain active. Thursday’s sunnier, less windy, still cool, but not as chilly-feeling as today. Look for an increase in clouds Friday, some potential warm frontal rain at night, then a push of much warmer air Saturday, which despite being breezy, will feel quite nice and can stay rain-free until a cold front swings through late in the day or at night. This sets up a cooler, breezy, but dry Easter Sunday as high pressure builds through the Great Lakes.

TODAY: A sun/cloud mix. Highs 48-55. Wind NW 10-20 MPH, gusts 25-30 MPH.

TONIGHT: Mostly clear. Lows 28-35. Wind NW 5-15 MPH, gusty.

THURSDAY: Mostly sunny. Highs 52-59. Wind NW 5-15 MPH, diminishing.

THURSDAY NIGHT: Clear. Lows 32-39. Wind variable under 10 MPH.

FRIDAY: Increasing clouds. Highs 53-60, coolest coast. Wind SE up to 10 MPH.

FRIDAY NIGHT: Cloudy. Chance of rain. Lows 45-52. Wind SE to S 5-15 MPH.

SATURDAY: A sun/cloud mix. A possible late day shower or thunderstorm favoring areas north and west of Boston. Highs 58-65 South Coast, 66-73 elsewhere. Wind SW 10-20 MPH, higher gusts.

SATURDAY NIGHT: Variably cloudy. A shower or thunderstorm possible early, favoring Boston south. Lows 45-52. Wind shifting to NW 5-15 MPH, higher gusts.

SUNDAY: Sun/cloud mix. Highs 56-63. Wind NW 10-20 MPH.

DAYS 6-10 (APRIL 21-25)

Continuing the long weekend, fair weather for Patriots Day April 21 with a cool coast and milder inland. Unsettled weather threats appear to time out for April 22 and 24 with passing low pressure systems – details to come.

DAYS 11-15 (APRIL 26-30)

Battle zone weather pattern between warm air to south and chilly air in eastern Canada. Potential for a stretch of unsettled weather and some larger temperature contrasts.
