DAYS 1-5 (APRIL 7-11)
No big changes, just some tweaks on this Sunday morning update. After Saturday’s damp start, the weather turned out very nice across the area. Today will be another nice one, but the location of high pressure allows sea breezes to develop, some coastal areas will be cooler today. Then we enter the dank tank as high pressure in eastern Canada and waves of low pressure that initially want to travel toward the St. Lawrence via New York do the typical spring detour and warp themselves in a way to travel just south of southern New England. This combination is a chilly one with dominant cloudiness and some wet weather as the lows pass by, with the greatest threats of rain coming Monday during the day and Tuesday at night. Still thinking the Red Sox get their home opener in, but it will be in less than pleasant conditions, as discussed on previous blog posts. By Wednesday, we should get into a little more of a northerly air flow with some drying. High pressure over the region on Thursday will provide fair and somewhat milder weather.

DAYS 6-10 (APRIL 12-16)
Brief warm-up possible on April 12 before a shot of chilly air returns for April 13 followed by a quick warm-up on April 14. Watching for another storm to impact the region in the April 15-16 time frame with rain and possible wind.

DAYS 11-15 (APRIL 17-21)
More chilly and possible damp weather to start the period then a trend to drier and milder thereafter.

9:45AM

DAYS 1-5 (APRIL 6-10)
A quick update on this Saturday morning. Some of you may have seen snowflakes and/or heard sleet pinging off your windows last evening as precipitation fell into dry air and chilled off the air just enough to support some frozen stuff, but that’s long gone now and in comes some milder air for your weekend as it dries out today and remains dry through Sunday. The difference on Sunday will be an onshore wind developing in coastal areas which end up cooler than they will be today (in most areas at least). Still, a nice weekend overall. Our weather situation becomes more complex as we get to the new week, with a low pressure system bringing rain into the region for at least the first half of Monday. What happens after that is going to depend on the position of a frontal boundary that trails behind the first low pressure area. Some parts of the region can end up in the 60s or be in the 40s depending on what side of the boundary they are on. For now, I am going to lean toward the cooler side, with air from the north and east coming in behind the initial low and never really being able to recover all the way through Tuesday, and probably even Wednesday. We will have to watch for an additional low pressure area close enough for more rain later Tuesday, hopefully after the Red Sox home opener, which may be taking place in very cool and raw weather.
Forecast details…
TODAY: Early showers depart Cape Cod area and clouds/drizzle/patchy fog dissipate elsewhere with a sun/cloud mix from mid morning onward.
Highs 52-59 south-facing shores, 58-65 elsewhere with 65-72 possible interior valley locations. Wind SW 5-15 MPH.
TONIGHT: Mostly clear. Patchy fog interior lower elevations. Lows 35-42. Wind light variable.
SUNDAY: Increasing clouds. Highs 55-62 except cooling back through the 50s along the coast. Wind light variable with sea breezes.
SUNDAY NIGHT: Cloudy. Rain arrives overnight. Lows 38-45. Wind light N.
MONDAY: Cloudy. Rain likely in the morning. Areas of drizzle/fog and scattered light rain afternoon. Highs 45-52. Wind NE 5-15 MPH.
MONDAY NIGHT: Cloudy. Areas of fog and drizzle. Lows 38-45. Wind NE 5-15 MPH.
TUESDAY: Mostly cloudy. Areas of drizzle. Patchy fog. Highs 45-52 coast, 52-59 interior. Wind NE 5-15 MPH.
TUESDAY NIGHT: Cloudy. Chance of rain. Areas of drizzle/fog. Lows 40-47. Wind variable up to 10 MPH.
WEDNESDAY: Variably cloudy. Highs 48-55. Wind N to NW 10-20 MPH.

DAYS 6-10 (APRIL 11-15)
Pattern will feature high pressure in Canada and waves of low pressure passing south of New England, possibly over New England. This is a cooler/unsettled pattern overall with wet weather likely centered around April 11-12. May briefly warm up toward the end of the period with fair weather returning.

DAYS 11-15 (APRIL 16-20)
Pattern may try to readjust, starting cooler and ending milder, but it remains to be seen if that will be a longer-term shift.

7:09AM

DAYS 1-5 (APRIL 5-9)
The pattern we see develop during this 5-day period is typical of spring – high pressure in Canada, series of low pressure areas passing near or south of southern New England. It’s a cool and unsettled pattern overall, but that doesn’t mean we can’t sneak in some milder weather, and we will do just that for a part of the weekend. The first low pressure system brings wet weather by tonight to very early Saturday, but we do salvage a good part of the weekend, later Saturday through much of Sunday, with dry weather, before the next low arrives for a rainy Monday. Tuesday, the Boston Red Sox home opener, does not look like a stellar spring day but rather a more typical one with onshore flow and at least a fair amount of cloudiness. It does, however, look like Monday’s steadier rain will be out of the picture by then. If things were to move a little more quickly, we could get rid of the easterly wind for a more northerly or even westerly one, but I would say odds are against that at this point.
Forecast details…
TODAY: Clouding over. Rain arriving west and south of Boston late afternoon, overspreading all areas early evening. Highs 40-47. Wind E 5-15 MPH.
TONIGHT: Cloudy with rain evening, may briefly mix with or turn to snow some areas mainly west of Boston favoring higher elevations, tapering to drizzle and scattered rain showers with patchy fog overnight. Lows 35-42 evening, rising through the 40s overnight. Wind SE 5-15 MPH becoming S.
SATURDAY: Cloudy morning with areas of fog and drizzle and a chance of rain showers early. Mostly cloudy to partly sunny afternoon. Highs 52-59 south-facing shores, 58-65 elsewhere with 65-72 possible interior valley locations. Wind SW 5-15 MPH.
SATURDAY NIGHT: Mostly clear. Patchy fog interior lower elevations. Lows 35-42. Wind light variable.
SUNDAY: Increasing clouds. Highs 55-62 except cooling back through the 50s along the coast. Wind light variable with sea breezes.
SUNDAY NIGHT: Cloudy. Rain arrives overnight. Lows 38-45. Wind light N.
MONDAY: Cloudy. Rain likely. Highs 45-52. Wind E 5-15 MPH.
MONDAY NIGHT: Cloudy. Rain tapering to drizzle. Areas of fog. Lows 38-45. Wind E 5-15 MPH.
TUESDAY: Mostly cloudy. Areas of drizzle. Patchy fog. Highs 45-52 coast, 52-59 interior. Wind E to N 5-15 MPH.

DAYS 6-10 (APRIL 10-14)
Pattern will feature high pressure in Canada and waves of low pressure passing south of New England, possibly over New England. This is a cooler/unsettled pattern overall with wet weather likely centered around April 11. May briefly warm up toward the end of the period with fair weather returning.

DAYS 11-15 (APRIL 15-19)
Overall similar pattern looks like it may remain in place. Too early to tell which days would be coolest and which potentially milder, and which will be wetter, but will fine-tune going forward.

7:37AM

DAYS 1-5 (APRIL 4-8)
The big storm that went by the region yesterday and caused all the wind last night is still having some impact today with a gusty breeze, but high pressure moving closer to the region will bring dry weather. A weak disturbance and some cold air aloft will pop some passing clouds today but overall a nice day. Low pressure approaches from the west Friday, spreading clouds back in, with wet weather by late day and nighttime for most if not all of the region, lingering until very early Saturday before it departs, leaving us with a decent weekend. By Monday, the next low pressure system is in with more wet weather.
Forecast details…
TODAY: Sun and passing clouds. Highs 46-53. Wind NW 10-20 MPH.
TONIGHT: Mostly clear. Lows 30-37. Wind light N to NE.
FRIDAY: Cloudy. Rain develops by late afternoon but may start as snow/mix in some areas. Highs 40-47. Wind E 5-15 MPH.
FRIDAY NIGHT: Cloudy with rain, tapering to drizzle with patchy fog overnight. Lows 35-42. Wind SE 5-15 MPH.
SATURDAY: Cloudy/fog/drizzle and a chance of rain showers morning. Mostly cloudy to partly sunny afternoon. Highs 55-62. Wind variable 5-15 MPH becoming SW.
SATURDAY NIGHT: Mostly clear. Lows 32-39. Wind light variable.
SUNDAY: Partly sunny. Highs 55-62 except cooling back along the coast. Wind light variable with coastal sea breezes.
SUNDAY NIGHT: Increasing clouds. Lows 35-42. Wind light N.
MONDAY: Cloudy. Rain likely. Highs 45-52. Wind E 5-15 MPH.

DAYS 6-10 (APRIL 9-13)
Pattern will feature high pressure in Canada and waves of low pressure passing south of New England, possibly over New England. This is a cooler/unsettled pattern overall and will have to work out timing detail for wet weather. The first date-of-importance is April 9 for Red Sox home opener which currently looks like a damp start then drying out, but possibly not that warm at all.

DAYS 11-15 (APRIL 14-18)
A sneaky warmer day or 2 is possible but the overall pattern doesn’t look like it wants to change too much through mid month.

7:31AM

DAYS 1-5 (APRIL 3-7)
The balance was tipped slightly too mild and not enough precipitation intensity for the snow to visit most of the region this morning. Still possible some mix occurs before mid morning in southeastern MA under a heavier band of precipitation, which has been generally rain. Either way, the bomb of a storm that is causing this will pass southeast of Cape Cod today and intensify a bit more as it heads toward eastern Canada. Its expanding wind field will cause a moderate to strong west wind later today as the air dries out rapidly. But this drying air coming off the hills and mountains to the west will also allow it to get rather mild, so this time you won’t be feeling the chill of winter behind the departing storm. It will turn cooler for Thursday and Friday however, and a disturbance may kick off some clouds Thursday before a low pressure area from the Ohio Valley spreads a more vast cloud canopy into the region Friday, followed by a rain threat later Friday, that may start as snow briefly in some areas. The bulk of this system will move through Friday night and may make the very start of the weekend gloomy early Saturday, but improving conditions will follow for the balance of the weekend as high pressure takes over. It will end up on the milder side, but coastal areas probably turn cooler with sea breezes on Sunday.
Forecast details…
TODAY: Overcast start with rain, may mix with snow briefly southeastern MA, then a clearing trend west to east. Highs 50-56 Cape Cod, 57-63 elsewhere. Wind N 10-20 MPH, higher gusts especially eastern coastal areas morning, then W 15-30 MPH with gusts 35-45 MPH afternoon.
TONIGHT: Mostly clear. Lows 28-35. Wind W 15-30 MPH and gusty early, diminishing slightly overnight.
THURSDAY: Sun then clouds. Highs 46-53. Wind NW 10-20 MPH.
THURSDAY NIGHT: Partly cloudy evening. Mostly cloudy overnight. Lows 30-37. Wind light N to NE.
FRIDAY: Cloudy. Rain develops afternoon but may start as snow/mix in some areas. Highs 40-47. Wind E 5-15 MPH.
FRIDAY NIGHT: Cloudy with any snow/mix going to rain, then rain tapering to drizzle with patchy fog overnight. Lows 35-42. Wind SE 5-15 MPH.
SATURDAY: Cloudy/fog/drizzle and a chance of rain showers morning. Mostly cloudy to partly sunny afternoon. Highs 52-59. Wind variable 5-15 MPH.
SATURDAY NIGHT: Clear. Lows 32-39. Wind light variable.
SUNDAY: Partly sunny. Highs 55-62 except cooling back along the coast. Wind light variable with coastal sea breezes.

DAYS 6-10 (APRIL 8-12)
A quick push of warm air is possible early in the period before we return to a cooler and somewhat unsettled pattern. There’s some uncertainty as to how it plays out at this point. Much fine-tuning to do.

DAYS 11-15 (APRIL 13-17)
Chilly start, brief warm up, then may cool down yet again. Overall pattern should be drier however, but this is still a low confidence forecast for now.

7:25AM

DAYS 1-5 (APRIL 2-6)
High pressure retreats to the east today but the day itself will be nice after a cold start. Low pressure will intensify off the Mid Atlantic Coast later today and track north northeastward, passing southeast of New England Wednesday. Its closest pass during the first half of Wednesday will put its precipitation shield over southeastern New England, as mainly rain, but can still get a mix with or flip to snow toward the end if it is heavy enough. This remains possible pretty much anywhere except Cape Cod, despite a short range model shift slightly eastward with lighter precipitation. These models do not always pick up banding features that can result in enhanced precipitation, so I’m not going to blindly model-follow and just wipe the chance off the board. Either way, it’s all gone midday Wednesday and clearing quickly follows for an afternoon much different than the morning was. A cooler shot of air arrives Thursday along with an upper level disturbance that will bring some cloudiness to the region. After that, low pressure approaches from the Ohio Valley Friday, and wet weather is expected by Friday night (this may start as snow in some areas) lingering into at least part of Saturday.
Forecast details…
TODAY: Sunshine followed by increasing clouds. Highs 40-47. Wind light NE shifting to SE.
TONIGHT: Cloudy. Rain arriving south to north, may mix with or change to snow starting with higher elevations of north central MA and southwestern NH then work eastward toward dawn. Lows 30-37. Wind E 10-20 MPH shifting to N, gusts above 20 MPH interior, above 30 MPH coast, and possibly above 40 MPH Cape Cod.
WEDNESDAY: Cloudy with rain/mix/snow except just rain Cape Cod, accumulations of a coating to 1 1/2 inch possible if it is heavy enough, otherwise little or no accumulation, ending as rain by late morning west to east. Clearing afternoon. Highs 50-57. Wind N 10-20 MPH, higher gusts.
WEDNESDAY NIGHT: Clear. Lows 28-35. Wind NW 10-20 MPH and gusty.
THURSDAY: Sun then clouds. Highs 45-52. Wind NW 10-20 MPH.
THURSDAY NIGHT: Partly cloudy evening. Mostly cloudy overnight. Lows 30-37. Wind light N to NE.
FRIDAY: Cloudy. Rain develops afternoon but may start as snow/mix in some areas. Highs 40-47. Wind E 5-15 MPH.
FRIDAY NIGHT: Cloudy with any snow/mix going to rain, then rain tapering to drizzle with patchy fog overnight. Lows 35-42. Wind SE 5-15 MPH.
SATURDAY: Cloudy/fog/drizzle and a chance of rain showers morning. Mostly cloudy to partly sunny afternoon. Highs 48-55. Wind variable 5-15 MPH.

DAYS 6-10 (APRIL 7-11)
Warm front approaches April 7 and after that it’s a little uncertain whether or not we get into the warm sector sometime April 8 and/or April 9 before we’re back on the cooler side of the boundary. Unsettled weather is possible any time during this 5-day period.

DAYS 11-15 (APRIL 12-16)
This period may start and end cool and somewhat unsettled with a chance of a fair, milder interlude between. Low confidence forecast.

7:20AM

DAYS 1-5 (APRIL 1-5)
March came in like a lion, and according to the old weather proverb should have exited like a lamb. Almost did. The weekend was certainly mild enough for a good portion of it to put one in the lamb frame of mind, but the rain and flip to colder air before it ended might have made you think more zebra. Well, whatever you call it, March is over, and now it’s onto April. I’ll spare you any April Fools Day jokes today and let those more qualified to fib handle that. Here it’s just time to get to the weather outlook, and that’s the absolute truth. High pressure approaches today, with us on the chilly side of it with a gusty northwest wind, making the day feel more late winter-like. High pressure moves across the region tonight then to the east of the region Tuesday while low pressure off the Mid Atlantic Coast intensifies and moves north northeastward. This large ocean storm would be a significant impact if its track was going to be a little further north and west, but it will be more of a side swipe with some rain/snow in the early hours of Wednesday before it scoots away to sea. Behind it will come a chilly north to northwest air flow later Wednesday through Thursday. An upper disturbance may kick off some cloudiness on Thursday. By Friday, an approaching low pressure area from the Ohio Valley will spread more cloudiness and eventual wet weather into the region, mainly rain, that may start as a mix or snow for some locations with just enough cold air lingering at the start. When we get to the end of the first 5 days of the month you’ll remember them as being on the cold and somewhat unsettled side, despite being dry the majority of the time.
Forecast details…
TODAY: Mostly sunny. Highs 38-45. Wind NW 15-25 MPH.
TONIGHT: Clear. Lows 28-35. Wind N 5-15 MPH.
TUESDAY: Clouding up. Highs 40-47. Wind light NE shifting to SE.
TUESDAY NIGHT: Cloudy. Rain/mix/snow possible favoring southern and eastern areas late night. Lows 30-37. Wind E 10-20 MPH and gusty shifting to N.
WEDNESDAY: Cloudy with a chance of rain favoring Cape Cod early, then clearing. Highs 43-50. Wind NW 10-20 MPH and gusty.
WEDNESDAY NIGHT: Clear. Lows 28-35. Wind NW 10-20 MPH and gusty.
THURSDAY: Sun then clouds. Highs 45-52. Wind NW 10-20 MPH.
THURSDAY NIGHT: Partly cloudy evening. Mostly cloudy overnight. Lows 30-37. Wind light N to NE.
FRIDAY: Cloudy. Rain develops but may start as snow/mix in some areas. Highs 40-47. Wind E 5-15 MPH.

DAYS 6-10 (APRIL 6-10)
Low pressure departs April 6 which starts gloomy and ends brighter, but cool. Fair, milder inland and cool coast April 7-8, then a warm-up April 9 before unsettled and cooler weather arrives to end the period.

DAYS 11-15 (APRIL 11-15)
Unsettled and cool start to the period, then fair weather returns with a gradual warm-up toward near normal temperatures.

7:18AM

DAYS 1-5 (MARCH 31-APRIL 4)
We get to this final day of March with no big surprises or big changes to the forecast. We’re in the warm sector to start the day, and as mentioned many times the southerly air flow is a cooler air flow for places closer to and along the South Coast, or any south-facing shores, as the air passes over much cooler water before arriving there. We will end today with the arrival of a colder air mass from the west, and the band of rain showers along the boundary will push west to east across the region this afternoon, exiting early this evening. For the start of April, we’ll be back into much cooler air and will have to watch for an offshore storm to be close enough to possibly bring a period of precipitation Tuesday night and early Wednesday. This system should be a fairly quick mover, and if it does impact the region, it will be very short-lived. A weak area of high pressure will move in with fair weather at midweek, but an upper disturbance may kick off some cloudiness at times especially Thursday.
Forecast details…
TODAY: Variably cloudy. Rain showers crossing the region west to east during the afternoon. Highs 48-55 South Coast, 56-63 most other areas but 64-71 possible some interior areas. Wind SW 10-20 MPH shifting to W late in the day.
TONIGHT: Mostly cloudy with rain showers possible eastern areas early, then clearing. Lows 30-37. Wind NW 10-20 MPH, higher gusts.
MONDAY: Partly sunny. Highs 38-45. Wind NW 15-25 MPH.
MONDAY NIGHT: Clear. Lows 28-35. Wind N 5-15 MPH.
TUESDAY: Clouding up. Highs 40-47. Wind light N to E.
TUESDAY NIGHT: Cloudy. Rain/mix/snow possible favoring southern and eastern areas. Lows 30-37. Wind N 10-20 MPH and gusty.
WEDNESDAY: Cloudy with a chance of rain favoring Cape Cod early, then clearing. Highs 43-50. Wind NW 10-20 MPH and gusty.
WEDNESDAY NIGHT: Clear. Lows 28-35. Wind NW 10-20 MPH and gusty.
THURSDAY: Sun then clouds. Highs 45-52. Wind NW 10-20 MPH.

DAYS 6-10 (APRIL 5-9)
Current expected timing of systems would bring low pressure from the Ohio Valley to New England April 5-6 with a period of wet weather likely late April 5 to early April 6 in southern New England. Fair with a brief warm-up April 7, then high pressure from eastern Canada bringing cooler weather April 8 before it quickly warms again at the end of the period with mostly fair weather.

DAYS 11-15 (APRIL 10-14)
Passing frontal systems about April 10 and 12 or 13 with minor bouts of unsettled weather otherwise mainly dry with typical up and down temperatures heading toward the middle of the month.

9:17AM

DAYS 1-5 (MARCH 30-APRIL 3)
The final weekend of March is a lesson in putting too much stock into forecasts several days in advance. Some of them would have had you believe it was a lock beach-style weekend. Even my own forecast hinted at 70+. I put caveats in, maybe not strongly enough. As the days went on we were looking at 2 “usual suspects” that appear this time of year, one being a frontal boundary from the north and the other being the ocean’s influence. Both come into play in at least delaying some warmth and modifying some temperatures. The second of the two was never in doubt. The first, in doubt initially, was something fine-tuned through the week. And the running forecast the last couple of days heading toward this weekend depicted a scenario that will be reasonably close to what happens. The third wildcard regarding the weekend was the timing of a cold front from the west on Sunday. Later timing, warmer with later showers. Earlier timing, a wetter day and turning much cooler. It turns out the answer is really somewhere in between those. It’ll start out mild, showers won’t rush in, but they will arrive later, and we will see a temperature drop-off before the day is over from west to east. So you see, sometimes weather forecasting is pretty simple, like forecasting a sunny day with light wind and a sea breeze the other day with high pressure atop the region, and sometimes it’s nothing like that, with many players to take into account. Once we get beyond this, the first 3 days of April will showcase the forecast contrast yet again, with an easy chilly/dry Monday forecast then a more complex and uncertain outlook for later Tuesday and Wednesday as we monitor the evolution of an offshore storm that likely gets close enough to at least put its cloud shield over the area, and may be close enough to at least graze the region with its precipitation shield as well, and that precipitation shield may be occurring with air cold enough to support something other than just rain. So it’ll be time to get the fine-tuning knobs ready once again. Spring in New England!
Forecast details…
TODAY: Mostly cloudy, gradually becoming partly cloudy from south to north. Highs 54-71, coolest South Coast, warmest interior valleys, but warmest readings not being reached in northern areas until late day. Wind light E gradually shifting to S and SW increasing to 5-15 MPH from south to north.
TONIGHT: Partly cloudy. Lows 48-55. Wind SW 5-15 MPH.
SUNDAY: Variably cloudy. Rain showers crossing the region west to east during the afternoon. Highs 48-55 South Coast, 56-63 most other areas but 64-71 possible some interior areas. Wind SW 10-20 MPH shifting to W late in the day.
SUNDAY NIGHT: Mostly cloudy with rain showers possible eastern areas early, then clearing. Lows 30-37. Wind NW 10-20 MPH, higher gusts.
MONDAY: Partly sunny. Highs 38-45. Wind NW 15-25 MPH.
MONDAY NIGHT: Clear. Lows 28-35. Wind N 5-15 MPH.
TUESDAY: Clouding up. Highs 40-47. Wind light N to E.
TUESDAY NIGHT: Cloudy. Rain/mix/snow possible favoring southern and eastern areas. Lows 30-37. Wind N 10-20 MPH and gusty.
WEDNESDAY: Cloudy with a chance of rain morning. Clearing afternoon. Highs 43-50. Wind NW 10-20 MPH and gusty.

DAYS 6-10 (APRIL 4-8)
Current expected timing of systems would bring an upper disturbance across the region with some cloudiness April 4, a small area of high pressure with fair and milder weather April 5, a low pressure area with unsettled weather April 6, improving and milder weather April 7, and a front from the north with a chill-down April 8.

DAYS 11-15 (APRIL 9-13)
Expecting some up and down temperatures with fair weather to start and end the period and some unsettled weather in between.

7:29AM

DAYS 1-5 (MARCH 29-APRIL 2)
A few minor tweaks being made to this forecast, the most notable one being to slow the timing of the return of the front that passes as a cold front today moving back tonight and Saturday as a warm front. It may take until the end of the day for that front to completely get itself back to the north and everyone into the warm sector, so this will happen lastly in northeastern MA and southern NH later Saturday. A cold front crosses the region later Sunday, which itself will be a fairly mild day until nightfall. As April gets underway, we’ll be back in the chill, and we will be watching a storm south of the region by late Tuesday.
Forecast details…
TODAY: Mostly cloudy. Scattered rain showers. Highs 48-55 coastal areas, 56-63 interior. Wind variable 5-15 MPH becoming W.
TONIGHT: Mostly cloudy. Patchy fog interior lower elevations. Lows 44-51. Wind W 5-15 MPH becoming N to NE.
SATURDAY: Mostly cloudy, gradually becoming partly cloudy from south to north. Highs 50-65, coolest South Coast, but warmest readings not being reached in northern areas until late day. Wind light E gradually shifting to S and SW increasing to 5-15 MPH from south to north.
SATURDAY NIGHT: Partly cloudy. Lows 48-55. Wind SW 5-15 MPH.
SUNDAY: Variably cloudy. Rain showers crossing the region west to east during the afternoon. Highs 48-55 South Coast, 56-63 most other areas but 64-71 possible some interior areas. Wind SW 10-20 MPH shifting to W late in the day.
SUNDAY NIGHT: Mostly cloudy with rain showers possible eastern areas early, then clearing. Lows 30-37. Wind NW 10-20 MPH, higher gusts.
MONDAY: Partly sunny. Highs 38-45. Wind NW 15-25 MPH.
MONDAY NIGHT: Clear. Lows 28-35. Wind N 5-15 MPH.
TUESDAY: Clouding up. Highs 40-47. Wind light N to E.

DAYS 6-10 (APRIL 3-7)
Offshore storm may be close enough to bring some precipitation early in the period. A disturbance from the west brings cloudiness and a slight precipitation threat about April 6. Temperatures mostly below normal.

DAYS 11-15 (APRIL 8-12)
Although the upper air pattern looks warm the surface pattern may have other ideas and keep it much more seasonable to even at times cool. A couple bouts of unsettled weather are possible during this period.

7:27AM

DAYS 1-5 (MARCH 28-APRIL 1)
High pressure sinks south of the region today and a cold front approaches and sort-of passes through tonight into Friday, coming to a stop somewhere over or just south of the region before retreating back to the north later Friday and Saturday. This should be possible as the high to the south will be a little stronger than the one to the north, and in many cases when we see the cold air win out, this time the warmer air should. But all the usual caveats are still there: Eastern coastal areas may take a little longer to warm, southern coastal areas will be much cooler as a south or southwest wind is onshore there. Regardless, a stronger cold front will be coming in from the west on Sunday, and again its exact timing will help determine temperature and any rain threat. Still leaning toward most of the day being on the warmer side and shower activity being limited. A band of scattered showers may form ahead of the main front earlier in the day with the main band of rain showers waiting until later with the front itself. Will fine-tune these details the next few days. By Monday, the first of April, it may feel a bit like winter again.

MONDAY: Partly sunny. Highs 38-45. Wind NW 15-25 MPH.

DAYS 6-10 (APRIL 2-6)
Temperatures below normal much of this period. Watching for an ocean storm early period that may brush or graze the area with rain/mix/snow then more unsettled weather is possible both April 4 and 6 based on current timing.

DAYS 11-15 (APRIL 7-11)
Nearby boundary results in uncertain and low confidence temperature and weather forecast but for now continuing the same idea of leaning toward near to below normal temperatures with at least a couple bouts of potential unsettled weather. That said, not seeing a signal for an excessively wet period of weather either.

DAYS 1-5 (MARCH 27-31)
A chilly start, a warm-up, and a quick chill-down during these final 5 days of March. High pressure controls the weather to start this period, being overhead today which starts cold but feels reasonably comfortable by later morning on with strong late March sun and light wind. As high pressure slips to the south, a warm-up begins Thursday and nearly gets thwarted Friday as a cold front moves into the region, but this front does not have a lot of push with it and will basically run out of gas and then be pushed back to the north later Friday. The maximum part of the warm-up will be Saturday when we’re in the strongest southwesterly flow, but this wind will keep the South Coast cool as the air will be coming right off the chilly ocean. The timing of a cold front approaching from the west is key for Sunday’s weather and temperature, with guidance ranging from early day to late day on the front’s timing. Been leaning later the last few days and will continue to do this for now.

DAYS 6-10 (APRIL 1-5)
A much cooler start to April. The wildcard is whether or not there will be any storminess or it will be largely dry. Need to watch a wave of low pressure to the south that may evolve into an ocean storm south to southeast of the region. Whether or not it gets close enough to bring rain and possibly mix/snow remains to be seen. If that system is far enough offshore, we may warm up right at the end of the period.

DAYS 11-15 (APRIL 6-10)
We’ll be near a boundary, so neither the weather nor the temperature forecast can be made with high confidence at this point. Leaning toward the cooler side of normal for temperatures with a couple precipitation threats. Even though the upper air pattern looks warmer, the surface pattern says “eh, not so much” with wind from cooler north and east more often than milder south and west.

7:39AM

DAYS 1-5 (MARCH 26-30)
High pressure will be in control of the weather the next few days, with southern New England starting out on the cold side of it today, right under it Wednesday, and on the milder side of it by Thursday. A cold front will move into the region from the northwest Thursday night and run out of gas over the area early Friday before shifting back to the north later Friday, and as high pressure strengthens a bit more to the southeast versus a weaker one to the north, the warmer air should win out later Friday through Saturday, with ocean-modified areas being cooler based on wind direction, which coming from the south and southwest, would have greatest impact on the South Coast area.
Forecast details…
TODAY: Some cloudiness South Coast region early otherwise sunny. Highs 38-45. Wind N 5-15 MPH.
TONIGHT: Clear. Lows 25-32. Wind light N.
WEDNESDAY: Sunny. Highs 45-50 coast, 50-55 interior. Wind light variable with sea breezes.
WEDNESDAY NIGHT: Partly cloudy. Lows 27-34. Wind light SE.
THURSDAY: Partly sunny. Highs 48-55 except 55-62 interior valleys. Wind light S.
THURSDAY NIGHT: Mostly cloudy. Risk of brief rain showers. Lows 40-47. Wind SW 5-15 MPH.
FRIDAY: Partly sunny. Highs 48-55 coastal areas, 56-63 interior. Wind variable up to 10 MPH, becoming SW 5-15 MPH.
FRIDAY NIGHT: Partly cloudy. Patchy fog interior lower elevations. Lows 45-52 evening, may rise overnight. Wind SW 5-15 MPH.
SATURDAY: Partly cloudy. Highs ranging from 48-55 South Coast to 56-63 interior southern areas to 64-71 most other areas with a few warmer readings possible interior valleys. Wind SW 10-20 MPH.

DAYS 6-10 (MARCH 31-APRIL 4)
Watching the timing of a cold front from the west March 31, leaning toward a mild to warm day overall with rain showers holding off until later. Fair, much cooler April 1. Watch for a passing storm to produce rain/mix/snow sometime April 2 to early April 3, another system with mix/rain showers later April 3 to early April 4 as temperatures run mostly below normal.

DAYS 11-15 (APRIL 5-9)
We’ll be near a boundary, so neither the weather nor the temperature forecast can be made with high confidence at this point. Leaning toward the cooler side of normal for temperatures with a couple precipitation threats.

7:20AM

DAYS 1-5 (MARCH 25-29)
A cold front is moving through the region without any fanfare, just cloudiness, early this morning and will set up a dry but chilly first few days of the week, followed by a warming trend later in the week as high pressure, which arrives from Canada early in the week, finds its way southeast of the region by late in the week. By late Friday though, we’ll have a cold front approaching from the northwest… Forecast details…
TODAY: Limited sun with lots of clouds morning. Increasing sun north to south midday on. Highs 45-52. Wind NW 5-15 MPH with higher gusts.
TONIGHT: Clear. Lows 25-32. Wind NW 5-15 MPH.
TUESDAY: Sunny. Highs 38-45. Wind N 5-15 MPH.
TUESDAY NIGHT: Clear. Lows 25-32. Wind light N.
WEDNESDAY: Sunny. Highs 45-50 coast, 50-55 interior. Wind light E.
WEDNESDAY NIGHT: Partly cloudy. Lows 27-34. Wind light SE.
THURSDAY: Partly sunny. Highs 48-55 except 55-62 interior valleys. Wind light S.
THURSDAY NIGHT: Partly cloudy. Lows 40-47. Wind SW 5-15 MPH.
FRIDAY: Partly cloudy. Highs 48-55 South Coast, 56-63 elsewhere. Wind SW 5-15 MPH.

DAYS 6-10 (MARCH 30-APRIL 3)
The March 30-31 weekend temperatures will depend on the position of a front nearby. For now I’m leaning toward the region being on the warmer side of it and staying with the ongoing forecast but it likely won’t be a totally sunny weekend, and a slight shift east and south of the position of that boundary will result in a vastly different temperature profile in the region. Much cooler air should be here to start April and there may be a period of rain which may end as snow April 1 with a slow clearing trend after.

DAYS 11-15 (APRIL 4-8)
We’ll be near a boundary, so neither the weather nor the temperature forecast can be made with high confidence at this point. Leaning toward the cooler side of normal for temperatures but limited precipitation.

8:24AM

DAYS 1-5 (MARCH 24-28)
Quick update this morning. High pressure southwest of the region delivers milder air today. A cold front drops through from north to south early Monday returning cold air to the region early in the week, with a slow recovery in temperatures beginning during midweek as high pressure from Canada sinks slowly southward through the period and keeps it dry. Forecast details…
TODAY: Mostly sunny. Highs 48-55 Cape Cod and immediate South Coast, 55-62 elsewhere. Wind W 5-15 MPH with gusts 20-30 MPH.
TONIGHT: Mostly cloudy. Lows 37-44. Wind W 5-15 MPH.
MONDAY: Mostly cloudy start with a slight risk of brief light rain. Clearing north to south mid morning on. Sunny afternoon. Highs 45-52 early then falling back through the 40s. Wind NW 5-15 MPH with higher gusts.
MONDAY NIGHT: Clear. Lows 25-32. Wind NW 5-15 MPH.
TUESDAY: Sunny. Highs 38-45. Wind N 5-15 MPH.
TUESDAY NIGHT: Clear. Lows 25-32. Wind light N.
WEDNESDAY: Sunny. Highs 45-50 coast, 50-55 interior. Wind light E.
WEDNESDAY NIGHT: Partly cloudy. Lows 27-34. Wind light SE.
THURSDAY: Partly sunny. Highs 48-55 except 55-62 interior valleys. Wind light S.

DAYS 6-10 (MARCH 29-APRIL 2)
High pressure southeast of the region will result in above to much above normal temperatures March 29-31 based on current expecting timing of the next front from the west. Ocean-influenced areas will obviously have modified temperatures. It should turn much cooler and somewhat unsettled in the first couple days of April with a front moving through and low pressure moving in. Too early for details on that.

DAYS 11-15 (APRIL 3-7)
Cooler weather for the early days of April with a couple periods of unsettled weather likely.
