DAYS 1-5 (APRIL 13-17)

A summer preview today as high pressure both surface (to our south) and aloft dominates the weather and allows for a big warm-up with a dry westerly wind. Only areas along the irregular coastline that have a westerly wind off some ocean water first will be cooler (parts of the North Shore, South Coast, and especially outer Cape Cod as well as Martha’s Vineyard and Nantucket). Many other locations should reach or exceed 80 for the first time this year. After a warm evening and very mild overnight tonight, it will look like a repeat of today when tomorrow dawns, but a weaker westerly air flow is going to allow for a healthy sea breeze to get going in most coastal areas, keeping it considerably cooler there compared to inland. And to add to that, a back-door cold front is likely to swing through the region anyway from northeast to southwest during the afternoon and evening hours, slowing down as it heads southwestward during the night. This sets up a much cooler day for many areas Saturday, though with a larger temperature spread from coastal areas to furthest inland reaches of the WHW forecast area, but also along with more cloudiness for the area. Low pressure approaching from the south southwest on Sunday will send a band of showers into the region in the pre-dawn hours, but this area of showers is expected to be on the wane, producing the most widespread coverage along the South Coast before fading and fizzling, leaving the region with a broad but weak onshore (easterly) air flow Sunday, mainly cloudy weather, and perhaps a bit of drizzle. Heading into Monday (Patriots Day), low pressure from the west will send a more solid band of rain showers into the region, with timing critical regarding any impact of early festivities regarding the holiday, and of course the Boston Marathon and Red Sox game. Current leaning is later-day / evening for the best rain chance with the bulk of outdoor activities being held before it arrives. Will continue to monitor and update this part of the forecast as necessary…

TODAY: Sunny. Highs 80-87 except 70s portions of North Shore and South Coast, 60s Cape Cod / Islands. Wind W 5-15 MPH.

TONIGHT: Clear. Lows 53-60. Wind W up to 10 MPH.

FRIDAY: Mostly sunny. Highs 77-84 except significantly cooler in coastal locations. Wind W up to 10 MPH with coastal sea breezes developing.

FRIDAY NIGHT: Partly cloudy. Lows 50-57. Wind shifting to NE 5-15 MPH.

SATURDAY: Partly sunny. Highs 60-67, coolest coast. Wind NE 5-15 MPH.

SATURDAY NIGHT: Mostly cloudy. Showers likely South Coast pre-dawn. Lows 46-53. Wind E up to 10 MPH.

SUNDAY: Mostly cloudy. Chance of showers mainly early morning. Patchy drizzle favoring the coast. Highs 52-59, coolest coast. Wind E up to 10 MPH.

SUNDAY NIGHT: Mostly cloudy. Chance of a shower. Lows 45-52.Wind SE 5-15 MPH.

MONDAY: Mostly cloudy. Chance of showers, mainly late in the day. Highs 55-62, coolest coast. Wind SE-S 5-15 MPH.

DAYS 6-10 (APRIL 18-22)

Upper level low pressure hanging around the region may cause a few showers early in the period with somewhat cooler weather expected. Generally fair/seasonable with high pressure in control at mid period. Additional unsettled weather possible toward the end of the period.

DAYS 11-15 (APRIL 23-27)

Eyeing the potential for a more solid rain producing system early to mid period with near to below normal temperatures, followed by a drying trend.

DAYS 1-5 (APRIL 12-16)

Our dry stretch of weather with above normal temperatures continues. Today’s temperatures may be down a few degrees over yesterday’s in much of the area due to a slightly cooler air mass moving in behind a cold front, but this is not a strong push of cool and the temperatures will still be above normal, but again along with a gusty breeze, this time from the northwest, keeping brush fire danger quite high. High pressure surface and aloft helps us warm even more tomorrow. This was a day I thought the coast was more vulnerable to a sea breeze, but right now I think the westerly wind may be strong enough to keep that away longer, or even prevent it in some areas (the exception being the limited locations of southeastern New England where the coast is west-facing, like the western shore of outer Cape Cod for example). So, contrary to my previous ideas, Boston does have a shot of hitting 80 on Thursday for the first time this season if the sea breeze is held at bay long enough, or doesn’t develop. While it remains quite warm Friday, coastal areas will be much more vulnerable to sea breeze development, and those areas will be cooler that day. A back-door cold front will then sweep across the region Friday evening or night, putting an end to the warmest weather, and while temperatures will still run above normal over the weekend, it will be a far cry from the summer-like warmth of the previous couple days. We’ll also see more cloudiness arriving Saturday, and especially Sunday as weak low pressure approaches from the south and a low pressure trough approaches from the west

TODAY: Partly sunny. Highs 62-69 except cooler Outer Cape Cod / Islands. Wind NW 10-20 MPH.

WEDNESDAY NIGHT: Clear. Lows 45-52. Wind W up to 10 MPH.

THURSDAY: Sunny. Highs 75-82, cooler Cape Cod. Wind W 5-15 MPH.

THURSDAY NIGHT: Clear. Lows 48-55. Wind W up to 10 MPH.

FRIDAY: Sunny. Highs 78-85 except significantly cooler in coastal locations. Wind W up to 10 MPH with coastal sea breezes developing.

FRIDAY NIGHT: Partly cloudy. Lows 50-57. Wind W 5-15 MPH shifting to NE.

SATURDAY: Partly sunny. Highs 60-67, coolest coast. Wind NE 5-15 MPH.

SATURDAY NIGHT: Mostly cloudy. Lows 46-53. Wind E up to 10 MPH.

SUNDAY: Mostly cloudy. Chance of a shower. Highs 57-64, coolest coast. Wind SE up to 10 MPH.

DAYS 6-10 (APRIL 17-21)

Watching a batch of showers for sometime on Patriots Day (April 17) but leaning toward an early-morning timing, leaving a drying westerly wind to follow for the Boston Marathon and Red Sox game, though early morning activities in Lexington / Concord MA may be impacted by wet weather. April 18-21 feature mostly dry weather other than a few showers associated with upper level low pressure early in the period, a cool start then a warming trend.

DAYS 11-15 (APRIL 22-26)

Eyeing the potential for a more solid rain producing system around mid period with near to below normal temperatures.

DAYS 1-5 (APRIL 11-15)

Brush fire danger goes up today and remains quite high through Wednesday as we enter a period of increased wind. This will take place as the pressure gradient tightens up between high pressure to the south and low pressure passing to the north. The dry spell goes on though as the rain shower activity associated with a cold front trailing the low will stay to our north. We warm up nicely today and end up just a little bit cooler behind the frontal boundary on Wednesday. With winds blowing healthily from the land, sea breezes will be generally non-existent so coastal areas will share in milder air despite the gusty breeze. While the warm-up gets even stronger Thursday and Friday as high pressure dominates both at the surface and aloft, the coast becomes more vulnerable to sea breezes again with a weaker wind field. A back-door cold front will move into the region from the northeast Friday night or Saturday with a more widespread cool-down, but still temperatures will remain above normal, and warmest away from the coast.

TODAY: Sun filtered by lots of high clouds. Highs 67-74 except cooler Cape Cod / Islands. Wind W 5-15 MPH and gusty.

TONIGHT: Variably cloudy. Lows 42-49. Wind W 5-15 MPH.

WEDNESDAY: Partly sunny. Highs 62-69 except cooler Outer Cape Cod / Islands. Wind NW 10-20 MPH.

WEDNESDAY NIGHT: Clear. Lows 45-52. Wind W up to 10 MPH.

THURSDAY: Sunny. Highs 70-77 except significantly cooler in coastal areas. Wind W up to 10 MPH with developing coastal sea breezes.

THURSDAY NIGHT: Clear. Lows 48-55. Wind W up to 10 MPH.

FRIDAY: Sunny. Highs 78-85 except significantly cooler in coastal locations. Wind W up to 10 MPH with redeveloping coastal sea breezes.

FRIDAY NIGHT: Partly cloudy. Lows 50-57. Wind W 5-15 MPH shifting to NE.

SATURDAY: Partly sunny. Highs 60-67, coolest coast. Wind NE 5-15 MPH.

DAYS 6-10 (APRIL 16-20)

A weak low pressure area from the south and a trough of low pressure and frontal boundary approaching from the west turn April 16 into a mostly cloudy day with a few isolated to scattered showers possible during the day and a more solid band of showers moving through west to east at night, potentially hanging around to very early April 17 (Patriots Day / Marathon Monday), but indications are now that we dry out for the bulk of the Boston Marathon and the late-morning-starting Red Sox game. Will continue to monitor and fine-tune this forecast since it’s still a number of days away. Generally dry, cooler weather expected after that into the middle of next week before a moderating trend following.

DAYS 11-15 (APRIL 21-25)

Dry weather indications to start, unsettled weather chances mid and/or late period. Temperatures showing a cooling trend relative to normal.

DAYS 1-5 (APRIL 10-14)

A dry weather pattern will continue through the next 5 days, but there will be some weather changes to occur. First, high pressure controls today with a chilly start and a warmer afternoon but a cooling coastal sea breeze likely. An approaching trough of low pressure will increase the wind flow from the west on Tuesday, a mild to warm day, with increased brush fire danger. This trough will bring some cloudiness into and through the region Tuesday night and off and on through Wednesday as well, with continued gusty wind and high brush fire danger. Very slightly cooler air will arrive behind the passage of a weak cold front associated with the trough for Wednesday – down a few degrees from Tuesday but still mild nonetheless. Dominant high pressure both surface and aloft means a more significant warm-up Thursday and Friday, but there will be an exception for coastal areas, vulnerable to sea breezes both days.

TODAY: Sunny. Highs 53-60 coast, 60-67 inland. Wind variable up to 10 MPH with coastal sea breezes developing.

TONIGHT: Clear. Lows 33-40. Wind variable to W up to 10 MPH.

TUESDAY: Sunshine, filtered later in the day by variable high cloudiness. Highs 66-73 except cooler Cape Cod / Islands. Wind W 5-15 MPH and gusty.

TUESDAY NIGHT: Variably cloudy. Lows 42-49. Wind W 5-15 MPH.

WEDNESDAY: Partly sunny. Highs 62-69 except cooler Cape Cod / Islands. Wind NW 10-20 MPH.

WEDNESDAY NIGHT: Clear. Lows 45-52. Wind W up to 10 MPH.

THURSDAY: Sunny. Highs 70-77 except significantly cooler in coastal areas. Wind W up to 10 MPH with developing coastal sea breezes.

THURSDAY NIGHT: Clear. Lows 48-55. Wind W up to 10 MPH.

FRIDAY: Sunny. Highs 78-85 except significantly cooler in coastal locations. Wind W up to 10 MPH with redeveloping coastal sea breezes.

DAYS 6-10 (APRIL 15-19)

April 15-16 weekend: Back-door cold front cools the region Saturday but with dry weather continuing. Very weak low pressure trough from the south and west brings more clouds with a rain shower chance later Sunday. Early to middle part of next week: Trough and frontal boundary passing by April 17 (Patriots Day) with rain shower threat – unsure of timing regarding daytime Red Sox game and Boston Marathon but will monitor / fine-tune, then drier, cooler weather following that system.

DAYS 11-15 (APRIL 20-24)

Dry weather indications to start, unsettled weather chances mid and/or late period. Temperatures showing a cooling trend relative to normal.

DAYS 1-5 (APRIL 9-13)

Happy Easter to all who celebrate it! A quick update for your Sunday. Long dry stretch of weather got underway recently and will continue through this 5-day period as high pressure dominates both at the surface and aloft. As previously stated, the position of the surface high helps determine the daily temperature profile. We start out with a cold morning and a little recovery for this afternoon. A warm-up is slated for early to midweek, being temporarily slowed Wednesday as a trough of low pressure swings through early that day, but with just some cloudiness (rain stays to north). Coastal areas will be vulnerable to sea breezes today and Monday, but a stronger land breeze is expected Tuesday and Wednesday with more influence from the trough’s approach and passage. Those 2 days will also see higher brush fire danger due to combined dry weather and more wind. Thursday, a stronger warm-up takes place but again with lighter wind, the sea breeze can develop and thwart the warm-up in many coastal locations.

TODAY: Sunny. Early to mid morning temperatures ranging from the middle 20s to middle 30s, rising into the 40s late morning and midday, peaking with highs 48-55, coolest coast, this afternoon. Wind N to variable up to 10 MPH with developing coastal sea breezes.

TONIGHT: Clear. Lows 33-40. Wind variable up to 10 MPH.

MONDAY: Sunny. Highs 53-60, coolest coast. Wind variable up to 10 MPH with coastal sea breezes.

MONDAY NIGHT: Clear. Lows 37-44. Wind W up to 10 MPH.

TUESDAY: Sunny to partly cloudy. Highs 63-70 except 55-62 Cape Cod region. Wind W 5-15 MPH.

TUESDAY NIGHT: Partly cloudy. Lows 42-49. Wind W 5-15 MPH.

WEDNESDAY: Partly cloudy to sunny. Highs 61-68, except cooler Cape Cod. Wind NW 5-15 MPH.

WEDNESDAY NIGHT: Clear. Lows 45-52. Wind W up to 10 MPH.

THURSDAY: Sunny. Highs 70-77 except significantly cooler in coastal areas. Wind W up to 10 MPH with developing coastal sea breezes.

DAYS 6-10 (APRIL 14-18)

Warmest day Friday April 14 with lots of sun, but still cooler coastal areas with developing sea breezes. Watching for a back-door cold front to cool more of the region down over the weekend of April 15-16 with a few more clouds, especially later in the weekend. May stay quite mild still well inland. Trough / front from the west brings a rain shower chance sometime early the following week (April 17-18) as a stronger westerly flow takes over.

DAYS 11-15 (APRIL 19-23)

Dry weather indications to start, unsettled weather chances mid and/or late period. Temperatures near to slightly above normal.

DAYS 1-5 (APRIL 8-12)

High pressure’s dominance brings dry weather for the next several days. The position of high pressure’s center and its configuration will determine wind and therefore determine the temperature pattern in the region daily. Today, the high center in the Great Lakes and the lingering impact of low pressure far to the northeast will keep a northwesterly air flow going, not nearly as strong as yesterday, but keeping it cool with sub-normal high temperatures. The high center a little closer on Sunday means a weaker wind field and inland high temperatures a little bit above today’s levels, but also allows for a sea breeze to develop at the coast, keeping it cooler there. High pressure sinking to the south early to mid week allows a warmer westerly air flow to take over, but Monday the wind field should continue weak enough to allow for a sea breeze. We will then see a stronger land breeze tendency Tuesday and Wednesday, but sometime between late Tuesday and early Wednesday, a trough moving by to our north can push some cloudiness through the region – but it looks like it will stay rain-free as what little moisture this feature has to work with will stay to our north. Generally warmer weather is expected at this time.

TODAY: Sunshine, filtered by high clouds especially near the South Coast. Highs 46-53. Wind NW 5-15 MPH.

TONIGHT: Clouds linger South Coast region early, followed by clearing. Lows 28-35, coldest interior valleys. Wind NW under 10 MPH.

SUNDAY: Sunny. Highs 50-57, but falling back to the 40s along the coast. Wind N to variable up to 10 MPH with developing coastal sea breezes.

SUNDAY NIGHT: Clear. Lows 33-40. Wind variable up to 10 MPH.

MONDAY: Sunny. Highs 53-60, coolest coast. Wind variable up to 10 MPH with coastal sea breezes.

MONDAY NIGHT: Clear. Lows 37-44. Wind W up to 10 MPH.

TUESDAY: Sunny to partly cloudy. Highs 61-68 except 53-60 Cape Cod region. Wind W 5-15 MPH.

TUESDAY NIGHT: Partly cloudy. Lows 42-49. Wind W 5-15 MPH.

WEDNESDAY: Partly cloudy to sunny. Highs 61-68, except cooler Cape Cod. Wind NW 5-15 MPH.

DAYS 6-10 (APRIL 13-17)

High pressure both surface and aloft boost temperatures to above to much above normal April 13-14 with continued fair weather conditions. Watch for a back-door cold front mid period driven by Canadian high pressure to cool the region down, followed by potential unsettled weather April 16-17 as a trough approaches from the west.

DAYS 11-15 (APRIL 18-22)

Indications for another dry period, starting cool followed by moderation through mid period, then potential unsettled weather by the end of the period.

DAYS 1-5 (APRIL 7-11)

A long stretch of dry weather begins today, but some changes still occur. First, we start today with a blanket of cloud cover over southeastern portions of the region as the cold front that went through slides offshore and a southwesterly air flow aloft still keeps the clouds from departing quickly. AS this cloud deck moves off, the sun’s heating will trigger the development of fair weather clouds as colder air moves in aloft, associated with an upper level trough of low pressure swinging through the region. Also, watch for the wind to kick up nicely behind the cold front aided by both pressure gradient between Great Lakes high pressure and Canadian low pressure, and the mixing of the air mass due to the sun’s heating. Increased wind and dry weather also results in elevated brush fire danger. While this is ongoing, a cool air mass will be settling in and set us up for a fair but cool weekend with less wind as high pressure moves closer. A general northwesterly breeze is expected Saturday and with lighter winds on Sunday we can see the development of coastal sea breezes, but both days will feature plenty of sun. The sunnier pattern continues into early next week, and as high pressure sinks to the south and an upper level high pressure ridge becomes dominant, we’ll undergo a nice warm-up.

TODAY: Sun/cloud mix. Highs 52-59. Wind NW increasing to 15-25 MPH, gusts 30-40 MPH at times especially this afternoon.

TONIGHT: Clearing. Lows 26-33. Wind NW decreasing to 10-20 MPH.

SATURDAY: Mostly sunny. Highs 48-55. Wind NW 5-15 MPH.

SATURDAY NIGHT: Clear. Lows 31-38. Wind N up to 10 MPH.

SUNDAY: Sunny. Highs 50-57, coolest coast. Wind N up to 10 MPH except coastal sea breezes by afternoon.

SUNDAY NIGHT: Mostly clear. Lows 33-40. Wind W up to 10 MPH.

MONDAY: Mostly sunny. Highs 58-65, cooler Cape Cod. Wind W 5-15 MPH.

MONDAY NIGHT: Mostly clear. Lows 38-45. Wind W up to 10 MPH.

TUESDAY: Mostly sunny. Highs 61-68, cooler Cape Cod. Wind W 5-15 MPH.

DAYS 6-10 (APRIL 12-16)

High pressure remains dominant with continued above normal temperatures through mid period, then watch for Canadian high pressure to send a frontal boundary southward with a April 15-16 weekend cool-down. Generally dry weather is expected but may have to watch for a little unsettled weather by the very end of the period if a disturbance is present in coincidence with that frontal boundary.

DAYS 11-15 (APRIL 17-21)

During this period we become more vulnerable to a trough / disturbance from the west with increased chances for showers a couple times, but too soon to really time-detail anything. Temperatures somewhat variable, overall close to normal.

DAYS 1-5 (APRIL 6-10)

Today is the only day for the next several that there will be unsettled weather to talk about, and along with that a question to answer: Will the warm front make it through before the end of the day? The answer is yes, mostly. The frontal boundary we’re waiting on may never quite make it all the way through the coastal areas from Boston northward, even including a portion of southeastern NH away from the coast and adjacent northeastern MA. This is typical for an advancing warm air mass into our region, especially at this time of year – early to mid spring, when without a strong push of surface wind from the southwest, the cold/cool air is hard to dislodge. So while temperatures start out in the 40s today, except 50+ in a few locations to the south where the frontal boundary has already passed, we may end up with quite the temperature contrast by the end of the day with 70+ high temps over interior sections, especially with any sun-breaks, and staying stuck in the upper 40s to lower 50s from the city of Boston northward. Regardless of the position of that frontal boundary by day’s end, a fairly strong cold front will push across the region from northwest to southeast this evening. So a summary of our resultant weather from these fronts, parented by low pressure passing to our north, is a generally overcast morning with areas of fog and drizzle, breaks in the clouds and even partial sun where the warm air is successful in making an appearance, while clouds remain more solid and stubborn in the limited areas that the warm front does not pass by completely, a few rain showers around during the afternoon, and then a swath of rain showers and possible embedded thunder moving across the region from the end of the day into the evening hours. Later tonight, the front sweeps us clean and the sky clears as the air dries out and cools markedly. This sets up a stretch of dry weather from Friday into early next week. Friday-Saturday will be cooler than normal with diurnal fair weather clouds around both days, mixing with the sun, along with a gusty breeze as high pressure heading through the Great Lakes interacts with departing low pressure in eastern Canada with our typical squeeze-play pressure gradient here. With the low’s influence out of the picture by Sunday and Monday, and high pressure sinking to our south, we’ll undergo a warming trend, but it will be slow at first, so if you have Easter plans for Sunday, be aware that the morning will start out quite chilly.

TODAY: Overcast morning with areas of fog and drizzle, which may persist from Boston to the MA North Shore and NH Seacoast into the afternoon while clouds thin and break elsewhere with some partial sun possible. Isolated to scattered rain showers possible from mid afternoon on. Highs 48-55 southeastern NH and northeastern MA down to Boston proper as well as Cape Cod / Islands, 55-62 remainder of South Coast and just away from eastern coastal areas including the eastern Merrimack Valley, 63-70 elsewhere except 70+ possible in any inland areas that see any sunshine. Wind E-SE up to 10 MPH shifting to SW 10-20 MPH from south to north, but wind shift may never make it into aforementioned cooler locations.

TONIGHT: Mostly cloudy evening with rain showers and possible thunder. Clearing overnight. Lows 38-45. Wind SW 10-20 MPH shifting to NW, higher gusts.

FRIDAY: Sun and passing clouds. Highs 50-57. Wind NW 15-25 MPH and gusty.

FRIDAY NIGHT: Clear. Lows 33-40. Wind NW 10-20 MPH and gusty.

SATURDAY: Sunny start, then a sun/cloud mix. Highs 48-55. Wind NW 5-15 MPH and gusty.

SATURDAY NIGHT: Clearing. Lows 35-42. Wind W 5-15 MPH.

SUNDAY: Mostly sunny. Highs 54-61. Wind W 5-15 MPH.

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

MONDAY: Mostly sunny. Highs 57-64. Wind WSW 5-15 MPH.

DAYS 6-10 (APRIL 11-15)

High pressure will dominate our weather throughout this entire period with a dry spell. Temperatures warm to above normal through mid period, but we may be vulnerable to a back-door cold front and cool-down late period.

DAYS 11-15 (APRIL 16-20)

High pressure hangs on with more dry weather to start this period – temperatures initially cooler than another warm-up to follow. Later in the period a trough and frontal boundary approaching from the west would turn the weather more unsettled with an increased chance of rain showers.

DAYS 1-5 (APRIL 5-9)

Today is one of those April days that chills you under an overcast with an east wind, and even though it won’t be a wet day (at least for most of it) it may as well be for how raw the air will feel if you’re walking outside, especially near the coast. This occurs ahead of the front that slipped slowly by us as a cold front yesterday attempting to come back as a warm front as low pressure moves into the Great Lakes today. But these fronts typically have trouble moving back through as warm fronts, and this one will initially, finally doing so on Thursday morning, with a couple periods of rain from this evening to early in the morning, introducing a shot of mild and humid air to the region for several hours, until a cold front swings through with its own round of showers, maybe even a thunderstorm, Thursday evening. This will usher in a chilly air mass from Canada on a gusty wind for Friday, which will gradually settle down into Saturday, as high pressure moves through the Great Lakes in the wake of low pressure, which will have since departed via eastern Canada. The high pressure area will sink a little further south, keeping us dry but turning it milder Sunday.

TODAY: Cloudy. Patchy drizzle this afternoon. Chance of light rain late-day. Highs 45-52, coolest coastal areas. Wind E 5-15 MPH.

TONIGHT: Overcast. Periods of rain. Areas of fog. Temperatures hold 45-52. Wind SE 5-15 MPH.

THURSDAY: Mostly cloudy. A passing rain shower possible. Highs 55-62 coastal areas and 62-69 elsewhere but may not occur until later in the day. Wind SE 5-15 MPH shifting to SW 10-20 MPH with higher gusts, especially South Coast, but wind shift may not occur eastern and northern areas until later in the day.

THURSDAY NIGHT: Variably cloudy with a chance of rain showers and a slight chance of a thunderstorm evening. Clearing overnight. Lows 40-47. Wind SW 10-20 MPH shifting to NW, higher gusts.

FRIDAY: Sun and passing clouds. Highs 50-57. Wind NW 15-25 MPH and gusty.

FRIDAY NIGHT: Clear. Lows 33-40. Wind NW 10-20 MPH and gusty.

SATURDAY: Sunny start, then a sun/cloud mix. Highs 48-55. Wind NW 5-15 MPH and gusty.

SATURDAY NIGHT: Clearing. Lows 35-42. Wind W 5-15 MPH.

SUNDAY: Mostly sunny. Highs 56-63. Wind W 5-15 MPH.

DAYS 6-10 (APRIL 10-14)

High pressure will dominate our weather throughout this entire period with a dry spell. Temperatures near to above normal.

DAYS 11-15 (APRIL 15-19)

Indications are that the overall dry pattern may continue to dominate, but watch for a back-door cold front to potentially chill parts of the region down early in the period and maybe a Canadian cold front to do the same mid period. Unsettled weather episodes should be brief.

DAYS 1-5 (APRIL 4-8)

Some typically changeable spring weather is on our menu for the coming days, with quite the variety to be had during this 5-day period. It starts out with a cold front sinking slowly southward through our region today. This front will produce a lot of clouds, and some rain shower activity, first to the north, then more to the south, followed by a bit of a drying trend. Temperatures will run a wide range today, being warmest over interior southern portions of the region, cooler in coastal areas, and also across northern areas that lie north of the frontal boundary. Tonight, the front will have made it to the south of the region where it will also hang out during the day on Wednesday. While this happens, low pressure heads into the Great Lakes and any clearing we may see today will be short-lived, with clouds coming back, and more wet weather returning Wednesday. As the low heads north of our region Wednesday night and Thursday, it will finally pull the frontal boundary back to the north, and what is a raw and cool Wednesday will be followed by a shot of warm air for Thursday, and while clouds may never fully break, and there will still be a rain shower chance in the warm sector of the system, it will have the feel of later spring. There will of course be a modifying influence from a southwest wind near the South Coast where it will be much cooler than locations away from the coast. The cold front swings through Thursday evening with one more round of showers and even a few thunderstorms possible. This sets up dry and much cooler weather for late week, along with another episode of active wind between departing low pressure through eastern Canada and high pressure pressing eastward into the Great Lakes region.

TODAY: Heavier clouds southern NH and MA with some rain showers to start, while sun shines at first toward the South Coast, then clouds shift southward along with a chance of rain showers before eventually breaking for partial sun at times as rain showers come to an end from west to east. Highs 50-57 southern NH and all coastal areas, 58-65 interior MA and northeastern CT to northern RI. Wind N to NE up to 10 MPH in southern NH, variable under 10 MPH with coastal sea breezes developing.

TONIGHT: Mostly cloudy. Lows 38-45. Wind NE to E up to 10 MPH.

WEDNESDAY: Cloudy. Periods of light rain. Highs 45-52, coolest coastal areas. Wind E 5-15 MPH.

WEDNESDAY NIGHT: Cloudy. Chance of rain evening. Patchy fog. Temperatures steady 45-52. Wind SE up to 10 MPH.

THURSDAY: Mostly cloudy. Chance of rain showers and possibly a thunderstorm, mainly late in the day. Highs 62-69 except 55-62 South Coast. Wind SW 10-20 MPH, higher gusts.

THURSDAY NIGHT: Variably cloudy with a chance of rain showers and a slight chance of a thunderstorm evening. Clearing overnight. Lows 40-47. Wind SW 10-20 MPH shifting to NW, higher gusts possible.

FRIDAY: Sun and passing clouds. Highs 50-57. Wind NW 15-25 MPH and gusty.

FRIDAY NIGHT: Clear. Lows 33-40. Wind NW 10-20 MPH and gusty.

SATURDAY: Mostly sunny. Highs 48-55. Wind NW 5-15 MPH and gusty.

DAYS 6-10 (APRIL 9-13)

High pressure pushes to the south with fair, milder weather for April 9-10. Frontal boundary and passing trough may bring some unsettled weather and a cooling trend thereafter, but not sure of details at this point.

DAYS 11-15 (APRIL 13-17)

A battle between increasing spring warmth to our south and lingering Canadian chill sets up potential unsettled weather episodes and a difficult outlook for temperatures, but leaning toward the cooler side at this point.

DAYS 1-5 (APRIL 3-7)

High pressure brings nice weather today before a cold front settles southward into the region tonight with a possible rain shower. This front is going to initially hang up in the region with a somewhat complex temperature profile for Tuesday – cooler to the north and along the South Coast while interior southern portions of the region are likely warmest, despite a fair amount of cloudiness, which may produce a few more rain showers. The front will get a little extra push southward finally by Tuesday night as high pressure in eastern Canada noses southward down the coast (typical spring occurrence) as low pressure heads for the Great Lakes. That boundary will attempt to move back as a warm front as the warmer air from the approaching low surges northeastward, but as is typical also for springtime, the front will struggle to do so and Wednesday ends up cloudy, raw, cool, and damp. Eventually the front does make it by us and we “warm sector” for a while on Thursday but probably with lots of clouds (any sun and we end up warmer than the forecast will indicate). Watch for showers and a possible thunderstorm with the arrival and passage of a cold front late Thursday, leading to a dry, breezy, and much cooler day for Friday, as low pressure moves through eastern Canada.

DAYS 6-10 (APRIL 8-12)

Dry with moderating temperatures expected during the April 8-9 weekend as the weather will be dominated by a ridge of high pressure. Unsettled weather with a cooling trend expected as a trough of low pressure moves into the region thereafter.

DAYS 11-15 (APRIL 13-17)

Additional unsettled weather especially early in the period followed by a drier trend. Temperatures start below normal, then moderate.

DAYS 1-5 (APRIL 2-6)

After a brief shot of spring warmth late yesterday, broken by showers and thunderstorms last evening, we go back to the spring blustery chill today between approaching high pressure and departing low pressure. A lobe of instability brings clouds through the region this morning, but these will give way to sun by midday. High pressure will move into the region tonight, and while the cold hangs on for the night, we’ll lose the wind. Monday, a nice moderation in temperature takes place after a cold start, with plenty of sun. A cold front moves into the area Monday night and slows down, but it will be a weak front, producing only a few rain showers in the region, before it settles southward with a little push from a new high pressure area in eastern Canada. While Tuesday will be a somewhat mild day, it will be cooler along the coast due to an onshore wind. Low pressure is still slated to move into the Great Lakes region Wednesday and then into adjacent Canada Thursday. The warm front from this system will deliver clouds and damp weather to our area Wednesday. It looks like we will sneak into the warm sector of this low pressure area for a while on Thursday before its cold front passes through – meaning some additional unsettled weather.

TODAY: Lots of clouds passing through the region during this morning. Sunshine dominant with a few additional passing clouds this afternoon. Highs 42-49. Wind NW 15-25 MPH, gusty. Wind chill in the 30s.

TONIGHT: Clear. Lows 30-37. Wind NW 5-15 MPH, gusty.

MONDAY: Sunny. Highs 51-58. Wind W 5-15 MPH.

MONDAY NIGHT: Variably cloudy. Chance of a rain shower. Lows 41-48. Wind W up to 10 MPH shifting to N.

TUESDAY: Partly sunny. Highs 49-56, coolest coast. Wind NE to E up to 10 MPH.

TUESDAY NIGHT: Mostly cloudy. Lows 35-42. Wind E up to 10 MPH.

WEDNESDAY: Cloudy. Chance of rain. Highs 42-49. Wind E 5-15 MPH.

WEDNESDAY NIGHT: Cloudy. Chance of rain evening. Patchy fog. Temperatures steady 42-49. Wind SE up to 10 MPH.

THURSDAY: Mostly cloudy. Chance of rain showers. Highs 60-67 except 52-59 South Coast. Wind SW 10-20 MPH.

DAYS 6-10 (APRIL 7-11)

Dry April 7-9 .. starting cool/breezy behind low pressure early in the period, then moderating temperatures as high pressure slides to the south thereafter. Low pressure passes to north with warm front / cold front combo bringing some unsettled weather, changing temperatures, and shifting winds April 10-11.

DAYS 11-15 (APRIL 12-16)

Additional unsettled weather especially early to mid period followed by some drying. Temperatures start below normal, then moderate.

DAYS 1-5 (APRIL 1-5)

April’s arrival will be met with changeable weather today – a foggy start giving way to a rainy morning, a drier afternoon with sunshine for some, a shower or thunderstorm for some locations this evening, and a if you’re up later tonight and outside, you can feel the arrival of a cold air mass. Low pressure passing to our north causes this as its warm front saunters across the region from south to north this morning, putting us in the “warm sector” for midday and afternoon, before its cold front charges through from west to east this evening. Of course, while it turns quite mild across the region today, that warm air will be greatly modified closer to the South Coast where a southwesterly wind comes off chilly ocean water – typical for this time of the year of course. Sunday’s weather will be less changeable – a blustery, bright day, and quite a bit cooler than today. High pressure moves in for more tranquil conditions Sunday night into Monday, and as the high sinks to the south, it will warm up Monday afternoon decently, ahead of an approaching cold front. This front will have far less punch than its predecessor, bringing the chance of a rain shower to the region Monday night. Behind it, the air isn’t that cold, with most of the cooling coming from a light wind off the water in coastal areas on Tuesday. By Wednesday of next week, low pressure heading for the Great Lakes extends its warm front to just south of our region, and we can expect a general onshore air flow, and a cloudy day with a chance of some rainfall.

TODAY: Areas of fog early. Cloudy morning with rain, moderate to heavy at times. Breaking clouds and clearing with sunshine emerging especially northeastern CT and central through northeastern and east central MA and southern NH for the afternoon while clouds hang on longer to the southeast, eventually with some partial clearing in those areas as well. Highs 52-59 South Coast, 60-67 elsewhere. Wind varible up to 10 MPH except SW 10-20 MPH South Coast at first, then SW 15-25 MPH later with gusts 25-35 MPH, except 20-30 MPH with gusts 35-45 MPH Cape Cod & Islands.

TONIGHT: Mostly cloudy evening with rain showers and possible thunderstorms including some heavy downpours, even some small hail possible with any heavier storms favoring southwestern NH, central MA, and northeastern CT. Clearing overnight. Lows 35-42. Wind SW 10-20 MPH, higher gusts, shifting to NW overnight. Wind chill falling into the 20s.

SUNDAY: Sun and passing clouds. Highs 42-49. Wind NW 15-25 MPH, gusty. Wind chill in the 30s.

SUNDAY NIGHT: Clear. Lows 30-37. Wind NW 5-15 MPH, gusty.

MONDAY: Sunny. Highs 51-58. Wind W 5-15 MPH.

MONDAY NIGHT: Variably cloudy. Chance of a rain shower. Lows 41-48. Wind W up to 10 MPH shifting to N.

TUESDAY: Partly sunny. Highs 49-56, coolest coast. Wind NE to E up to 10 MPH.

TUESDAY NIGHT: Mostly cloudy. Lows 35-42. Wind E up to 10 MPH.

WEDNESDAY: Cloudy. Chance of rain. Highs 42-49. Wind E 5-15 MPH.

DAYS 6-10 (APRIL 6-10)

Unsettled weather likely lingers for the start of the period until a cold front trailing low pressure in eastern Canada goes by the region. There’s a lot of uncertainty in the weather that results from a somewhat complex pattern as we head through next week. Inconsistent guidance doesn’t help – showing fair/mild weather on one run for a given day only to decide it can snow on the next run. My overall feeling remains generally the same. I’m leaning toward a fair, cool mid period, a warm-up, to follow, then unsettled weather arriving at the end of the period. Don’t make any solid plans off this outlook as obviously a lot of fine-tuning is to come.

DAYS 11-15 (APRIL 11-15)

A cooler and more unsettled pattern arrives heading into mid April.

DAYS 1-5 (MARCH 31 – APRIL 4)

High pressure provides a bright start to the day today, but it will be a cold early morning as we had a clear sky and much less wind during the night, allowing for an efficient temperature drop. Clouds advance into the region by midday and thicken up this afternoon as a warm front approaches from the west, and this front will send a shield of precipitation across the region from late in the day into this evening – mainly rain, but may start as some wet snow and/or sleet mainly in the Route 2 corridor and Merrimack Valley through southern NH. Any frozen precipitation that does occur will not impact the roads with any icy conditions, however, as temperatures will remain above freezing and roads will just be wet. The main rain shield, accompanied by areas of drizzle and fog, will leave the latter two elements behind as it exits later this evening and the warm front passes the region. During our time in the warm sector Saturday, we’ll first see a slug of rain and embedded heavier showers move through during morning to midday, followed by a dry slot and rain-free conditions during the afternoon hours, during which some clearing will take place, however this may not reach the South Coast & MA South Shore until nearly sunset early in the evening. Less sun and a southwesterly wind, quite gusty, will limit temperature rise in those areas, but to the north and west where we have far less marine influence from southwest wind and more sunshine, look for 60+ high temps. We won’t be done with the rain threat yet, however. As its parent low still moves by to our north, a strong cold front will cross the region from west to east Saturday evening, accompanied by showers and possible thunderstorms. The thunderstorm threat will be greatest further west, in areas that received better heating and sit under a more unstable atmosphere, where some strong wind gusts and small hail may occur. This activity should fade in intensity as it moves eastward, then exits the coastal areas later in the evening. Dry, much cooler air then follows this overnight, and sets us up for a bright but blustery Sunday – similar to yesterday’s weather but maybe not quite as chilly. High pressure then builds in for dry and more tranquil weather Monday, with a cold start and a milder finish. But a weak colder front moving into the region Monday night may bring a few rain showers and set us up with a slightly cooler day on Tuesday as winds turn northeast to east behind the boundary, although cooling will be limited due to a weak delivery and an upper high pressure ridge in place.

TODAY: Sunny start, cloudy finish. Late-day rain reaching central MA and southwestern NH which may be mixed with some wet snow and/or sleet. Highs 43-50. Wind variable up to 10 MPH.

TONIGHT: Cloudy. Rain likely this evening. Areas of fog/drizzle. Temperatures steady 43-50 during the evening, rising slightly overnight. Wind SE up to 10 MPH shifting to SW 5-15 MPH with higher gusts.

SATURDAY: Cloudy with rain and embedded heavier showers morning. Clearing southern NH, northeastern CT and central through northeastern MA into Metro Boston during the afternoon while clouds hang on to the southeast with some partial clearing in those areas possible by evening. Highs 52-59 South Coast, 60-67 elsewhere. Wind SW 10-20 MPH with gusts 25-35 MPH, except 20-30 MPH with gusts 35-45 MPH Cape Cod & Islands.

SATURDAY NIGHT: Mostly cloudy evening with rain showers and possible thunderstorms including some heavy downpours, even some small hail possible with any heavier storms favoring southwestern NH, central MA, and northeastern CT. Clearing overnight. Lows 35-42. Wind SW 10-20 MPH, higher gusts, shifting to NW overnight.

SUNDAY: Sun and passing clouds. Highs 42-49. Wind NW 15-25 MPH, gusty.

SUNDAY NIGHT: Clear. Lows 30-37. Wind NW 5-15 MPH, gusty.

MONDAY: Sunny. Highs 51-58. Wind W 5-15 MPH.

MONDAY NIGHT: Variably cloudy. Chance of a rain shower. Lows 41-48. Wind W up to 10 MPH shifting to N.

TUESDAY: Partly sunny. Highs 49-56, coolest coast. Wind NE to E up to 10 MPH.

DAYS 6-10 (APRIL 5-9)

A broad low pressure area is expected to travel into the Great Lakes via the Midwest early in the period and a frontal boundary in our area extending from this will likely bring lots of cloudiness and possibly some wet weather to start the period. Eventually the low will make its way through eastern Canada and deliver a dry, cool air mass to our region around mid period, followed by continued fair weather but with a warm-up late in the period. This remains a lower confidence forecast at this time with fine-tuning to come.

DAYS 11-15 (APRIL 10-14)

A cooler and more unsettled pattern arrives heading into mid April.

DAYS 1-5 (MARCH 30 – APRIL 3)

A strong cold front moved through the region with some rain and snow showers overnight, but now we’re just in a blustery and chilly air mass for today, but with plenty of sunshine. It’s going to feel more like late-season football weather for the start of the baseball season at Fenway Park today! High pressure drifts overhead tonight and winds drop off, allowing for quite the cold night. Clouds advance Friday ahead of an approaching warm front that will bring a rainy Friday night our way, but this may start as sleet for some due to lingering cold air. The warm front will move through and set us up for a windy, warmer but frequently wet Saturday with rain showers. As low pressure passes to our north, it will drag a cold front through Saturday evening with a few last rain showers and maybe even a thunderstorm around with the front’s passage, setting us up for a breezy, cool Sunday, but with the return of dry weather. High pressure will build in for continued dry but more tranquil weather with less wind by Monday.

TODAY: Sunshine dominant, but a few passing fair weather clouds through midday. Highs 41-48.Wind NW 10-20 MPH and gusty. Wind chill in the 30s.

TONIGHT: Clear. Lows 25-32. Wind NW-N diminishing to under 10 MPH.

FRIDAY: Sun followed by clouds. Late-day rain possible, especially western portions of the region, which may begin as sleet. Highs 43-50. Wind variable up to 10 MPH.

FRIDAY NIGHT: Cloudy. Periods of rain and drizzle. Areas of fog. Temperatures steady 43-50. Wind SE shifting to SW 5-15 MPH.

SATURDAY: Cloudy. Rain showers likely. Highs 55-62. Wind SW 10-20 MPH, higher gusts.

SATURDAY NIGHT: Mostly cloudy evening with rain showers and possible thunderstorms including some heavy downpours. Clearing overnight. Lows 35-42. Wind SW 10-20 MPH, higher gusts, shifting to NW overnight.

SUNDAY: Sun and passing clouds. Highs 42-49. Wind NW 15-25 MPH, gusty.

SUNDAY NIGHT: Clear. Lows 30-37. Wind NW 5-15 MPH, gusty.

MONDAY: Sunny. Highs 50-57. Wind W 5-15 MPH.

DAYS 6-10 (APRIL 4-8)

Cold front swings through early in the period and its timing determines whether April 4 is a 60+ degree day for parts of the region or much cooler. April 5-7 is a period vulnerable to unsettled weather with variable temperatures, with the end of the period turning fair but breezy and chilly.

DAYS 11-15 (APRIL 9-13)

Some see-saw weather with a dry and milder trend early in the period then an unsettled cooler trend potentially following that.
