Monday Forecast

1:55AM

DAYS 1-5 (FEBRUARY 29-MARCH 4)…
A pair of cold fronts will come through the region, one midday today and one about midnight tonight. The final (extra) day of February will be quite mild, but colder air will arrive overnight to start March on a chilly note. Quick-moving systems mean that a warm front will approach during Tuesday with clouds rolling in. Its parent low will pass northwest of southern New England early Wednesday with a round of rain showers at some point Wednesday with a cold front. High pressure builds in with fair and chilly weather Thursday. Low pressure develops and moves south of the region by Friday, and with cold air in place we’ll have to watch for some mix/snow, though it’s a little early to determine how productive this system will be here in southern New England. It is even still possible this system is further south and misses most of if not all of the region.
TODAY: Sun starts and ends the day. Variably cloudy with a possible passing rain shower in between. Highs in the middle 50s to lower 60s. Wind SW 10-20 MPH with higher gusts, shifting to W in the afternoon.
TONIGHT: Mostly clear early and overnight. A period of cloudiness and maybe a snow flurry in between. Lows in the upper 20s to lower 30s. Wind W 10-20 MPH with higher gusts, shifting to NW overnight.
TUESDAY: Increasing clouds. Highs in the lower to middle 40s. Wind light NW shifting to E.
WEDNESDAY: Scattered light mix/rain morning. Rain showers likely early-mid afternoon. Late-day clearing. Lows in the 30s. Highs in the 50s.
THURSDAY: Mostly sunny. Lows in the 20s. Highs in the 30s.
FRIDAY: Mostly cloudy. Chance of snow/mix. Lows in the 20s. Highs in the 30s.

DAYS 6-10 (MARCH 5-9)…
Unsettled weather with possible periods of snow/mix March 5 to early March 6 as low pressure offshore is slow to depart. Fair later March 6. Possible unsettled weather from a weaker system later March 7 into March 8. Fair weather returns for March 9. Temperatures near to below normal.

DAYS 11-15 (MARCH 10-14)…
A milder start with mostly fair weather then a colder finish with possible unsettled weather.

Sunday Forecast

8:20AM

DAYS 1-5 (FEBRUARY 28-MARCH 3)…
No current changes to the discussion from yesterday, i.e., no changes in short term thinking and not confident enough beyond that to change anything that I wrote yesterday, so just an updated forecast…
TODAY: Clouds dominant morning. Sun dominant afternoon. Highs in the lower to middle 50s. Wind SW 10-20 MPH with higher gusts.
TONIGHT: Variably cloudy. Lows in the upper 30s to lower 40s. Wind SW 10-20 MPH with higher gusts.
MONDAY: Mostly cloudy with a slight chance of rain showers through midday, then becoming mostly sunny. Highs in the lower to middle 50s. Wind SW 10-20 MPH with higher gusts, shifting to WNW.
TUESDAY: Increasing clouds. Lows in the upper 20s to middle 30s. Highs in the 40s.
WEDNESDAY: Cloudy with rain possibly ending as snow followed by late-day clearing. Temperatures fall 40s to 30s.
THURSDAY: Mostly sunny. Lows in the 20s. Highs in the 30s.

DAYS 6-10 (MARCH 4-8)…
A broad low pressure trough carrying a couple of disturbances will bring chances for unsettled weather at times during this period along with temperatures near to slightly below normal. Too early to determine any kind of rain/mix/snow locations and intensity and timing.

DAYS 11-15 (MARCH 9-13)…
Fair weather returns early into mid period before the risk of unsettled weather returns beyond that. Temperatures near to slightly below normal.

Saturday Forecast

9:35AM

DAYS 1-5 (FEBRUARY 27-MARCH 2)…
High pressure retreats today but leaves lingering cold from the polar air mass that it delivered yesterday. A warm front arrives tonight with cloudiness but no precipitation, and brings a milder air mass in from the west for Sunday. Its parent low will travel eastward passing north of southern New England Monday while dragging a cold front through, but this particular front does not have much cold air behind it as it has traveled over a milder portion of the US and is not coming from colder sources further north. Eventually somewhat cooler air will sink down from Canada and this boundary will remain fairly close once it passes, coming back up into the region as a wavy frontal system by Tuesday and Wednesday, with more cloudiness and eventually some wet weather. At the tail end of this unsettled weather, there may be a risk of rain ending as snow as colder air arrives more quickly, but this is several days away and uncertain.
TODAY: Sunshine most of day. Clouds from the west late. Highs in the upper 30s. Wind SW 5-15 MPH increasing to 10-20 MPH with higher gusts late.
TONIGHT: Considerable cloudiness. Lows in the lower 30s before midnight then rising through the 30s. Wind SW 10-20 MPH with higher gusts.
MONDAY: Mostly cloudy with a chance of rain showers through midday, then becoming mostly sunny. Highs in the lower to middle 50s. Wind SW 10-20 MPH with higher gusts, shifting to WNW.
TUESDAY: Increasing clouds. Lows in the upper 20s to middle 30s. Highs in the 40s.
WEDNESDAY: Cloudy with rain possibly ending as snow followed by late-day clearing. Temperatures fall 40s to 30s.

DAYS 6-10 (MARCH 3-7)…
Fair and cold March 3. A broad low pressure trough carrying a couple of disturbances will bring chances for unsettled weather at times March 4-7 along with temperatures near to slightly below normal. Too early to determine any kind of rain/mix/snow locations and intensity and timing.

DAYS 11-15 (MARCH 8-12)…
Risk of unsettled weather early and again late period, with fair weather in between. Temperatures near to slightly below normal.

Thursday Forecast

7:29AM

DAYS 1-5 (FEBRUARY 24-29)…
Regarding the overnight wild weather (wind, thunderstorms, warmth), comments from you all are encouraged below, and I’ll be adding more later today, as my time for this update is limited this morning. As far as the forecast goes, no big changes for this update so will just move onto the updated forecast.
TODAY: Mostly cloudy to partly sunny with greatest chances for sunshine mid morning to early afternoon. Early lingering rain showers and a few downpours Nantucket and Cape Cod. Scattered rain showers returning from west to east late-day. Temperatures falling slowly through the 50s. Wind SW to W 15-25 MPH with higher gusts.
TONIGHT: Mostly cloudy with passing rain showers evening. Partly cloudy overnight. Lows in the 30s. Wind SW to W 15-25 MPH with higher gusts.

DAYS 6-10 (MARCH 1-5)…
Medium range models still having some issues with the pattern but the leaning is now for a rain/snow shower potential March 1, fair March 2, a storm threat with a track more likely through the Great Lakes March 3-4 favoring rain here, and fair weather returning March 5. Will fine-tune in the days ahead.

DAYS 11-15 (MARCH 6-10)…
Trending colder including unsettled weather threats including mix/snow at least 2 times during the period.

Wednesday Forecast

7:31AM

DAYS 1-5 (FEBRUARY 24-28)…
The weather’s gotten into the mood to be harder to forecast, but we like a challenge. After a nearly no-show on the snow portion part 1 of the storm system, the second part of it won’t be able to pull such a trick, as we’ll see periods of rain/drizzle today and that area of heavier rain coming through in the early morning hours of Thursday, and a trailing trough bringing a few more rain/mix showers Thursday evening and night. Still expecting drier and colder weather by Friday and a chilly start and milder finish to the coming weekend as additional cold air remains locked up in Canada.
TODAY: Overcast. Periods of rain/drizzle, though deepest valleys north central MA and southern NH may still see freezing rain/drizzle early. Areas of fog. Temperatures slowly rise through the 30s. Wind light E to variable.
TONIGHT: Overcast. Periods of rain/drizzle. Areas of fog. Heavier rain and a possible thunderstorm well after midnight from southwest to northeast. Temperatures rising through the 40s evening and into the 50s. Wind light E to SE shifting to S then increasing to 15-30 MPH with higher gusts.
THURSDAY: Cloudy through morning with periods of rain showers, possibly heavy, and a slight chance of thunderstorms. Sun/cloud mix midday. Mostly cloudy with a passing rain shower late day. Early-day highs around 60 then falling through the 50s and into the 40s by late day. Wind S to SW 15-30 MPH with higher gusts.
THURSDAY NIGHT: Mostly cloudy with a rain/mix shower evening. Partly cloudy overnight. Lows around 30. Wind SW to W 15-30 MPH with higher gusts.
FRIDAY: Partly cloudy and windy. Highs in the 30s. Wind W 15-25 MPH and gusty.
SATURDAY: Partly cloudy. Lows in the 20s. Highs 35-45.
SUNDAY: Partly sunny. Lows in the 30s. Highs 45-55.

DAYS 6-10 (FEBRUARY 29-MARCH 4)…
Mild with possible rain showers February 29. A few snow showers and colder March 1. Fair and chilly March 2. Risk of light mix and chilly March 3. Milder with rain showers possible March 4. This portion of forecast low confidence and subject to change.

DAYS 11-15 (MARCH 5-9)…
Fair early and late in the period. Unsettled mid period. Variable temperatures, averaging near to below normal.

Tuesday Forecast

7:34AM

DAYS 1-5 (FEBRUARY 23-27)…
Here comes the 2-part storm system with low pressure #1 delivering mix/snow to ice/rain from late today through tonight and low pressure #2 bringing a round of heavier rain and wind later Wednesday to early Thursday. A trailing trough from low #2 will bring a few additional showers of rain/mix late Thursday. We start out cold and this will be the reason for the frozen precipitation associated with low #1, but much milder air aloft and at the surface will take over as #1 passes and will be in place for #2. Drier and cooler weather is expected for the end of the week.
TODAY: Becoming cloudy. Snow/mix developing mid to late afternoon RI and southern MA, may start as rain South Coast and Cape Cod/Islands. Highs in the 30s. Wind NE 5-15 MPH.
TONIGHT: Cloudy. Snow/mix developing south to north then changing to rain except freezing rain interior valleys. Evening lows upper 20s to lower 30s then rising into 30s all areas overnight. Snow accumulation a coating to 1 inch coast from Boston south, 1-3 inches elsewhere. Wind NE to E 5-15 MPH.
WEDNESDAY: Overcast. Periods of rain/drizzle, though deepest valleys north central MA and southern NH may still see freezing rain/drizzle early. Areas of fog. Temperatures slowly rise into the 40s but may not get there until evening in some valleys. Wind light E to variable.
THURSDAY: Cloudy through morning with periods of rain showers, possibly heavy, and a slight chance of thunderstorms. Sun/clouds afternoon. Mostly cloudy with a passing rain shower at night. Temperature rise into the 50s morning, may reach 60 some areas, then fall back to the 40s evening.
FRIDAY: Partly cloudy. Lows in the 20s. Highs in the 40s.
SATURDAY: Partly cloudy. Lows in the 20s. Highs 35-45.

DAYS 6-10 (FEBRUARY 28-MARCH 3)…
Currently looks like the coldest air that was previously expected for February 28 will stay to the north and the day will be fair and seasonable. System from the west brings a chance of snow/mix/rain February 29. Fair and colder March 1-2. Storm threat March 3 but not sure on timing or any precipitation type this far in advance.

DAYS 11-15 (MARCH 4-8)…
Unsettled early in the period and again possibly at the end of the period. Temperatures below normal.

Monday Forecast

7:26AM

DAYS 1-5 (FEBRUARY 22-26)…
High pressure provides dry and seasonably chilly weather today. A complex storm system in 2 parts brings unsettled weather late Tuesday through early Thursday. An initial wave of low pressure will lift northward along the East Coast and run into lingering cold air with snow/mix overspreading southern New England during Tuesday evening before changing to rain at night as it warms up both surface and aloft. A frontal boundary left behind as this wave departs will keep damp to wet weather going on Wednesday then more rain will be generated by a second storm’s warm front. This larger system will pass west of New England and drag its cold front through by early Thursday with a band of heavier rain but very mild air just ahead of the front. By late Thursday and Friday it will turn somewhat colder, with a few rain showers around Thursday evening as a final trough of low pressure comes through, then dry weather Friday.
TODAY: Mostly sunny. Highs upper 30s to middle 40s. Wind NW 5-15 MPH.
TONIGHT: Mostly clear except partly cloudy eastern coastal areas and Cape Cod. Lows in the 20s. Wind N 5-15 MPH.
TUESDAY: Partly sunny to mostly cloudy. Highs in the 30s. Wind NE 5-15 MPH.
TUESDAY NIGHT: Cloudy. Snow/mix developing south to north then changing to rain. Minor snow accumulation. Temperatures steady in the 30s. Wind NE to E 5-15 MPH.
WEDNESDAY: Overcast. Periods of rain/drizzle. Areas of fog. Temperatures rise into the 40s.
THURSDAY: Cloudy through morning with periods of rain showers, possibly heavy, and a slight chance of thunderstorms. Sun/clouds afternoon. Mostly cloudy with a passing rain shower at night. Temperature rise into the 50s morning, may reach 60 some areas, then fall back to the 40s evening.
FRIDAY: Partly cloudy. Lows in the 20s. Highs in the 40s.

DAYS 6-10 (FEBRUARY 27-MARCH 2)…
Turning much colder during the course of the weekend February 27-28, coldest on Sunday, with snow shower/squalls possible at some point late Saturday to early Sunday. Chance of snow/mix February 29. Fair/cold March 1-2.

DAYS 11-15 (MARCH 3-7)…
Timing uncertain but one or 2 storm threats possible during this period. Temperatures below normal.

Sunday Forecast

7:41AM

DAYS 1-5 (FEBRUARY 21-25)…
Weak low pressure skirts southeastern New England with a touch of rain/snow tonight, otherwise generally fair weather will dominate today and Monday during each daytime. Fair weather continues Tuesday though clouds will advance ahead of a broad low pressure area in the eastern US. This low is likely to take a track over western New England or even further west than that by Thursday, returning unsettled weather to the region for midweek.
TODAY: Sun to clouds. Highs middle 40s to lower 50s. Wind W 5-15 MPH with higher gusts.
TONIGHT: Mostly cloudy early with a period of rain/mix/snow possible mainly southern MA to South Coast. Breaking clouds later. Lows upper 20s to lower 30s. Wind variable 5-15 MPH becoming mostly NE to N.
MONDAY: Mostly sunny. Highs around 40. Wind NW 10-20 MPH.
TUESDAY: Sunny start. Cloudy finish. Lows upper 10s to lower 20s. Highs in the 30s.
WEDNESDAY: Cloudy. Mix to rain. Temperatures rise 30s to 40s.
THURSDAY: Mainly cloudy with rain, possibly heavy, followed by partial clearing west to east by late. Temperatures rise 40s to 50s.

DAYS 6-10 (FEBRUARY 26-MARCH 1)…
Fair and chilly February 26. Risk of rain/snow showers February 27, slightly milder. Much colder with a chance of snow showers February 28. Fair and cold February 29 and March 1.

DAYS 11-15 (MARCH 2-6)…
Colder than normal with one or 2 storm threats possible during this period.

Saturday Forecast

9:02AM

DAYS 1-5 (FEBRUARY 20-24)…
Broad low pressure passing north of New England has put us into its warm sector after a period of warm frontal snow in much of southern New England late last night. Accumulations were modest, generally from nothing to a coating, which has since melted as the temperature climbed above freezing early this morning, and will continue to head for the lower 50s in many areas during the day as clouds eventually give way to sun. This storm’s so-called cold front will pass tonight and only knock temperatures down a tick or 2 for Sunday, still quite mild for the season, though like today, if you are outside you’ll have to deal with a gusty breeze, which will diminish later Sunday. A weak and fast-moving low pressure area will come racing along from the west southwest Sunday night and deliver a period of rain-to-snow to a good portion of southern New England, though favoring southern areas more than to the north. Any snow accumulation from this system will also be minor, and it will be gone by Monday. But it’s an active pattern right now, and yet another storm, this one larger, will threaten the region by Wednesday. The range of outcomes with that system is very wide at this stage, so no sharp detail will be attempted in this outlook at this point.
TODAY: Cloudy start with lingering sprinkles of rain then decreasing clouds and a sunnier afternoon. Highs upper 40s to lower 50s. Wind SW 10-20 MPH, higher gusts.
TONIGHT: Partly cloudy. Lows in the 30s. Wind SW 5-15 MPH, higher gusts.
SUNDAY: Sunny start then increasing high cloudiness probably blotting out the sun by the end of the day. Highs middle to upper 40s. Wind W 5-15 MPH, higher gusts, diminishing late.
SUNDAY NIGHT: Cloudy. Rain arrives, then changes to snow with minor accumulation, ending by about dawn. Lows upper 20s to lower 30s. Wind variable 5-15 MPH becoming mostly NE to N.
MONDAY: Early clouds especially Cape Cod, otherwise mostly sunny. Highs around 40. Wind NW 10-20 MPH.
TUESDAY: Sunny start. Cloudy finish. Lows upper 10s to lower 20s. Highs in the 30s.
WEDNESDAY: Storm of snow/mix/rain likely. Temperatures mostly in 30s.

DAYS 6-10 (FEBRUARY 25-29)…
The final days of February will likely be active but with low confidence on any details we’ll summarize it as a storm with a chance of rain/mix February 25, and another risk of unsettled weather in the February 27-29 period, and sort out the details as we get closer.

DAYS 11-15 (MARCH 1-5)…
The early days of March look colder than normal with a dry start and then a storm threat following.
