Tuesday Forecast

7:30AM

DAYS 1-5 (APRIL 11-15)
Taste of summer today but your typical cooler areas will continue on the South Coast and a weak sea breeze is also possible along the East Coast as the gradient wind will be a little weaker than it was Monday. But areas over the interior that don’t have an impact from the ocean air will see warmer readings in most cases than what took place on Monday. When we get to Wednesday a cold front will enter the region from the northwest and eventually exit via Cape Cod, but its journey through here will be good for the threat of showers and a few thunderstorms. Cooler weather arrives behind this front for Thursday and another disturbance may bring some cloudiness Thursday night and early Friday before high pressure builds in later Friday through early Saturday with more nice weather. A warm front approaching later Saturday will increase the cloudiness again and may lead to some wet weather at night.
TODAY: Sunshine and high clouds which may thicken up more later in the day. Highs 57-72 South Coast and immediate East Coast, 73-83 elsewhere except 83-88 in a few interior locations. Wind SW 5-15 MPH but East Coast sea breeze possible.
TONIGHT: Partly to mostly cloudy. Lows 50-57. Wind SW 5-15 MPH.
WEDNESDAY: Mostly cloudy. Scattered rain showers. Slight chance of thunderstorms. Highs 57-72, coolest South Coast. Wind W 5-15 MPH with higher gusts.
WEDNESDAY NIGHT: Mostly cloudy with a chance of rain showers early, then partly cloudy. Lows 45-52. Wind W 5-15 MPH with higher gusts.
THURSDAY: Mostly sunny through early afternoon. Partly cloudy later in the day. Highs 53-60. Wind NW 10-20 MPH with higher gusts.
FRIDAY: Partly cloudy early, then mostly sunny. Lows from the lower 40s to near 50. Highs from the middle 50s to around 60.
SATURDAY: Mostly sunny morning. Increasing clouds afternoon. Chance of light rain at night. Lows from the middle 30s to lower 40s. Highs from the middle 50s to lower 60s.

DAYS 6-10 (APRIL 16-20)
Fast-moving but weak systems. Timing is a little suspect, but currently expecting a warm-up for April 16, late-day or nighttime rain showers then dry and cooler weather April 17-18, warming up April 19 with late-day wet weather then clearing and cooling April 20.

DAYS 11-15 (APRIL 21-25)
Fast-moving systems bring quick changes but difficult to time this far in advance. Will toss the idea out there of a cool/dry start, wetter mid period, and drier/warmer end.

Monday Forecast

7:17AM

DAYS 1-5 (APRIL 10-14)
A warmer southwesterly flow will dominate through Tuesday and try to hang on Wednesday as a cold front arrives, bringing us our only chance of wet weather this work week. The cooler air does win out by Thursday and Friday though it will be dry.
TODAY: Mostly sunny. Highs 50-57 Nantucket, 57-68 South Coast, 68-77 elsewhere. Wind SW 10-20 MPH.
TONIGHT: Mostly clear. Lows 42-51. Wind SW 5-15 MPH.
TUESDAY: Mostly sunny morning. Partly cloudy afternoon. Highs 48-60 South Coast, coolest Nantucket and Cape Cod, 60-70 just inland from the South Coast and along the East Coast, 70-80 elsewhere. Wind SW 5-15 MPH but sea breeze possible East Coast.
WEDNESDAY: Variably cloudy. Chance of rain showers. Lows in the 50s. Highs from the middle 60s to lower 70s, cooler Cape Cod.
THURSDAY: Mostly sunny. Lows from the upper 30s to middle 40s. Highs in the 50s.
FRIDAY: Mostly sunny. Lows from the middle 30s to lower 40s. Highs in the 50s.

DAYS 6-10 (APRIL 15-19)
Fair with a warming trend over the April 15-16 weekend though a cold front may bring showers by the afternoon of Easter Sunday. Fair and cooler April 17-18, warming up at the end of the period.

DAYS 11-15 (APRIL 20-24)
Dry to start, then the pattern may turn a little wetter with time. Temperatures variable.

Sunday Forecast

8:15AM

DAYS 1-5 (APRIL 9-13)
And now the nicer weather pattern arrives, starting with a warmer west to southwest flow of air which will warm the region nicely, except the typically cooler South Coast, during the next few days. A weaker pressure gradient may leave the east coastal areas of MA and NH a little more vulnerable to a sea breeze on Tuesday. A weak cold front will knock the temperature back a little bit by Wednesday, which will be the only day with a rain shower threat, before a stronger front makes it cooler still by Thursday.
TODAY: Mostly sunny. Highs 47-55 South Coast, 56-63 elsewhere. Wind SW 5-15 MPH, higher gusts.
TONIGHT: Mostly clear. Lows 40-47. Wind SW 5-15 MPH.
MONDAY: Mostly sunny. Highs 47-52 Nantucket, 52-60 South Coast, 61-70 elsewhere except 70-75 some interior locations of MA/NH. Wind SW 10-20 MPH.
MONDAY NIGHT: Mostly clear. Lows 42-51. Wind SW 5-15 MPH.
TUESDAY: Mostly sunny morning. Partly cloudy afternoon. Highs 48-60 South Coast, coolest Nantucket and Cape Cod, 60-70 just inland from the South Coast and along the East Coast, 70-80 elsewhere. Wind SW 5-15 MPH but sea breeze possible East Coast.
WEDNESDAY: Variably cloudy. Chance of rain showers. Lows from the upper 40s to middle 50s. Highs from the upper 50s to middle 60s, cooler Cape Cod.
THURSDAY: Mostly sunny. Lows from the upper 30s to middle 40s. Highs in the 50s.

DAYS 6-10 (APRIL 14-18)
Going with a weaker and faster disturbance with minimal shower threat April 14 along with slightly milder air. Fair and cooler behind this April 15. Quick warm-up April 16 (Easter for those celebrating) with dry weather followed by a shower threat. Fair, cooler April 17-18 based on current timing but many days away so lower confidence as always.

DAYS 11-15 (APRIL 19-23)
The indications are for an overall drier than normal pattern with variable temperatures not far from normal overall bu with possible large day-to-day variation.

Saturday Forecast

10:32AM

DAYS 1-5 (APRIL 8-12)
Upper level low pressure drifts across the northeastern US today and a moderate northwesterly air flow at the surface will combine to produce lots of clouds and a cool, gusty breeze for your Saturday, but Sunday will be a different kind of day with a west to southwest breeze, sunshine and high clouds, and much milder air except in the typical spots cooled by a southwesterly wind (South Coast especially). The warm-up continues Monday-Tuesday before a weak cold front knocks it back a little bit by Wednesday.
TODAY: Variably cloudy. Highs 46-52. Wind NW 10-20 MPH, higher gusts.
TONIGHT: Partly cloudy. Lows 36-43. Wind W 5-15 MPH, higher gusts.
SUNDAY: Sun and high clouds. Highs 47-55 South Coast, 56-63 elsewhere. Wind SW 5-15 MPH, higher gusts.
SUNDAY NIGHT: Mostly clear. Lows 40-47. Wind SW 5-15 MPH.
MONDAY: Mostly sunny. Highs upper 45-52 Nantucket, 52-60 South Coast, 61-70 elsewhere except 70-75 some interior locations of MA/NH. Wind SW 10-20 MPH.
TUESDAY: Partly cloudy. Lows upper 40s to middle 50s. Highs upper 60s to upper 70s, cooler South Coast.
WEDNESDAY: Variably cloudy. Chance of rain showers. Lows upper 40s to middle 50s. Highs upper 50s to middle 60s, cooler Cape Cod.

DAYS 6-10 (APRIL 13-17)
Dry and cooler April 13. Watching for a possible disturbance bringing wet and cool weather for April 14 but low confidence on the strength and track of this system. Should be drier but cool April 15 before a warm-up at the end of the period.

DAYS 11-15 (APRIL 18-22)
Low confidence forecast with a possible boundary nearby and a battle between warm air to the south and much cooler air in eastern Canada probably resulting in wide-ranging temperatures and episodes of unsettled weather, but no major storms.

Friday Forecast

7:15AM

DAYS 1-5 (APRIL 7-11)
A broad and weakening area of low pressure leftover from yesterday’s unsettled weather will drift eastward across New England today and Saturday. During the passage of this feature it will be a little milder today but with clouds returning and a few showers possible, then slightly cooler with some clouds on Saturday. By Sunday through Tuesday, this will be replaced by a warmer southwesterly flow of air as high pressure situates itself off the East Coast and the jet stream lifts northward over southeastern Canada.
TODAY: Partly sunny morning. Mostly cloudy with scattered rain showers afternoon. Highs 48-55. Wind SW 5-15 MPH, higher gusts.
TONIGHT: Mostly cloudy. Rain showers ending from west to east. Lows 34-41. Wind 5-15 MPH.
SATURDAY: Variably cloudy. Highs 46-52. Wind NW 10-20 MPH, higher gusts.
SATURDAY NIGHT: Partly cloudy. Lows 36-43. Wind W 5-15 MPH, higher gusts.
SUNDAY: Sun and high clouds. Highs 47-55 South Coast, 56-63 elsewhere. Wind SW 5-15 MPH, higher gusts.
MONDAY: Mostly sunny. Lows in the 40s. Highs upper 40s Nantucket, 50s South Coast, 60s to lower 70s elsewhere.
TUESDAY: Partly cloudy. Lows upper 40s to middle 50s. Highs upper 60s to upper 70s, cooler South Coast.

DAYS 6-10 (APRIL 12-16)
Cold front may bring rain showers early April 12 then drier and cooler through April 13. Disturbance brings a shower risk April 14 then drier cooler still through April 15. May warm up again at the end of the period.

DAYS 11-15 (APRIL 17-21)
Low confidence forecast with a possible boundary nearby and a battle between warm air to the south and much cooler air in eastern Canada probably resulting in wide-ranging temperatures and episodes of unsettled weather. Will watch to see how this evolves.

Thursday Forecast

7:32AM

DAYS 1-5 (APRIL 6-10)
The next and last in a series of storms will move northeastward into the Great Lakes and send waves of rain into southern New England today. The remains of this low will drift eastward across the region Friday into Saturday with some lingering unsettled weather. Then things change as high pressure moves in Sunday-Monday with fair weather and a warm-up as winds eventually shift to southwest.
TODAY: Cloudy. Numerous rain showers and possible thunderstorms especially late morning and afternoon. Highs 43-50. Wind E to SE 5-15 MPH except 15-25 MPH southeastern MA, higher gusts late in the day.
TONIGHT: Cloudy evening with numerous rain showers and possible thunderstorms with heavy rain possible. Breaking clouds with isolated rain showers overnight. Temperature rise to 47-55. Wind S 10-20 MPH except 20-30 MPH southeastern MA, higher gusts possible.
FRIDAY: Mostly cloudy. Scattered rain showers. Temperatures steady 47-55. Wind S to SW 10-20 MPH, higher gusts.
SATURDAY: Mostly cloudy to partly sunny. Isolated rain/mix showers mainly early. Lows 33-40. Highs 40-47.
SUNDAY: Partly cloudy. Lows 37-43. Highs 50-58.
MONDAY: Partly cloudy. Lows 43-50. Highs 50-58 South Coast except 45-50 Nantucket, 59-68 elsewhere.

DAYS 6-10 (APRIL 11-15)
Dry and warm April 11 through watch for a possible back-door cold front by late. Some unsettled weather at times April 12-13 and still mild to seasonable should be followed by drier/cooler weather at the end of the period, though confidence remains somewhat low for this period of time.

DAYS 11-15 (APRIL 16-20)
Continued low confidence in how things go at this time but leaning toward a drier pattern with a cool start and a warmer finish.

Wednesday Forecast

7:26AM

DAYS 1-5 (APRIL 5-9)
Southern New England will sit in between storms today but in this break zone there is no blue sky and sunshine, just cloudy and damp weather with a light wind off the Atlantic. The next low pressure system moves rapidly northeastward into the Great Lakes Thursday with a ribbon of rain and thunderstorms coming into New England from the Southwest Thursday into Thursday night. The low pressure area cuts off and then drifts eastward across the region through Saturday with lingering unsettled weather. High pressure moves in by Sunday with very nice weather.

Monday Forecast

7:53AM

DAYS 1-5 (APRIL 3-7)
High pressure brings nice weather today for the Red Sox home opener. For the game expected sun and high clouds, a temperature in the upper to middle 40s, and a wind out of the east around 10 MPH. A couple of storms are on the horizon and the first will bring a decent bout of rain on Tuesday, with a follow up doing something similar later Thursday. A lingering trough in the region will keep lots of clouds and possible rain showers going through Friday.
TODAY: Sun and high clouds. Highs 48-53 coast, 54-59 interior. Wind light NW to N this morning, E up to 10 MPH this afternoon.
TONIGHT: Increasing clouds. Rain arriving southwest to northeast toward dawn, may mix with sleet central MA and southern NH briefly. Lows 33-38 interior, 38-43 coast. Wind SE 5-15 MPH.
TUESDAY: Overcast. Rain likely, possibly heavy at times. Slight chance of thunderstorms favoring the South Coast. Highs 41-48. Wind SE to E 10-20 MPH with higher gusts.

DAYS 6-10 (APRIL 8-12)
Upper low crosses the region with a few showers of rain/mix April 8. Fair weather and trending milder April 9-11. A few showers at the end of the period may introduce some cooling.

DAYS 11-15 (APRIL 13-17)
Hard to time a few ups/downs in temps but no major storms expected at this time.

Sunday Forecast

8:23AM

DAYS 1-5 (APRIL 2-6)
Active weather pattern continues. High pressure builds in tonight and hangs around Monday providing a nice day for the Red Sox home opener. The next storm arrives by early Tuesday with a good slug of rain (maybe mixed with sleet briefly in a few areas) but moves right along allowing another decent day Wednesday, although cloudiness may linger for a while. The next in a parade of storms arrives Thursday with the main body of this one looking like a decent rain event too. This pattern is quickly putting to shame my forecast for a drier trend beginning in April, but of much more importance is it is bringing needed rainfall to alleviate a still-ongoing drought.
TODAY: Partly cloudy to mostly sunny. Highs 43-50. Wind NW 5-15 MPH.
TONIGHT: Partly cloudy to mostly clear. Patchy black ice. Lows 29-36. Wind light NW.
MONDAY: Mostly sunny to partly cloudy. Highs 45-53. Wind light variable to light SE.
MONDAY NIGHT: Increasing clouds. Lows 33-40. Wind light SE.
TUESDAY: Overcast. Rain (brief sleet mix possible), may be heavy at times, before tapering off late. Highs 43-50. Wind SE to S 10-20 MPH with higher gusts, shifting to W late.
WEDNESDAY: Mostly cloudy to partly sunny. Lows 33-40. Highs 45-53.
THURSDAY: Clouding over. Chance of rain PM. Lows 33-40. Highs 43-50.

DAYS 6-10 (APRIL 7-11)
Unsettled with rain showers April 7 and rain/snow showers April 8. Next round of unsettled weather due late in the period. Temperatures generally below normal.

DAYS 11-15 (APRIL 12-16)
A brief warm-up may occur in the April 12-14 period before cooling again, though the weather may be a little less unsettled during this time.

Saturday Forecast

9:51AM

DAYS 1-5 (APRIL 1-5)
Long-duration storm continues. From my standpoint, the April Fools joke it played on me was putting the sleet/rain area further north and for a longer time that I expected. Officially, sleet still counts in the “snow” column when measuring for statistical purposes, but in a real-world scenario there is a difference, not only because it reacts differently underfoot and under tires, but also piles up much less (amount-wise) and more densely than snow. This will do a number on a forecast if you expected more of it to fall as snow. But now areas that were in this sleet/rain area are transitioning back to snow and areas that rained much of the storm will see the flip to sleet/snow as well during the morning as the storm center intensifies offshore. There will be enough moisture around for a few to several inches of additional snow where it already fell, and up to a few inches of snow where little or none has fallen. Look for generally up to 2 inches of snow south of the Mass Pike and 2-4 additional inches of snow to the north before it tapers off later today and this evening. A break comes Sunday and Monday with slightly milder air and dry weather. The next storm arrives Tuesday but looks like largely a rain event, although just enough cold air may be around at the surface for some mixing with sleet. This progressive system will be gone by Wednesday. The drier weather for Monday and Wednesday should allow the Red Sox to get their first 2 games of the regular season at Fenway Park in.
TODAY: Overcast. Snow southern NH and northern MA, sleet/rain to snow central and east central MA, rain to sleet to snow to the south. Precipitation tapering off west to east during the afternoon. Temperatures 30-40 may fall slightly. Wind NE to N increasing to 10-20 MPH with gusts to 30 MPH interior, 20-30 MPH with gusts 40-50 MPH coast, strongest southeastern MA.
TONIGHT: Mostly cloudy evening with some lingering light snow. Partly cloudy overnight. Lows 27-34. Wind N 10-20 MPH, higher gusts.
SUNDAY: Partly cloudy. Highs 43-50. Wind NW 5-15 MPH, higher gusts.
SUNDAY NIGHT: Mostly clear. Lows 27-34. Wind W 5-15 MPH becoming light variable.
MONDAY: Sunshine followed by increasing clouds. Highs 45-52. Wind light SE.
TUESDAY: Cloudy. Rain, possibly mixed with sleet. Lows 28-35. Highs 40-48.
WEDNESDAY: Variably cloudy. Lows 30-38. Highs 44-51.

DAYS 6-10 (APRIL 6-10)
Unsettled weather during the April 6-8 period a broad trough of low pressure moves through the region. Drier weather follows. Temperatures below normal.

DAYS 11-15 (APRIL 11-15)
Lower confidence here but may begin a transition to a different pattern with some unsettled weather early to mid period then milder weather following.

Friday Forecast (Update)

6:31PM

DAYS 1-5 (MARCH 31-APRIL 4)
The main precipitation is arriving and will continue through Saturday morning with a fairly wide swath of mixed rain/snow/sleet, dominated by sleet across central and eastern MA, with more rain to the south and snow to the north (far northern MA into NH). The rain/mix/snow line will head back to the southeast as the storm pulls away Saturday. Snow/sleet totals (through tomorrow) still break down this way: Under 1 inch South Coast including Cape Cod, southern RI, and southern CT, 1-2 inches northeastern CT, northern RI, and nearby southern MA eastward to the South Shore up to about the Mass Pike, 2-4 inches just north of the Mass Pike to northeastern MA and NH Seacoast with the lower amounts favoring the coast from Boston to Cape Ann, and 4 inches or more north central MA into interior southern NH. Also looking for quite a bit of wind as the storm intensifies offshore Saturday with some minor coastal flooding at the time of the mid afternoon high tide. A weak disturbance will bring some cloudiness and possibly a passing rain/snow shower Sunday. High pressure moves in Monday with dry but chilly weather for the Red Sox home opener. But the continued active pattern allows the next storm to be here Tuesday with what looks like mainly rain but possibly some sleet.
TONIGHT: Overcast. Snow with some sleet mixed in at times NH and far northern MA, sleet dominating with occasional snow/rain mixed in through much of central and east central MA, and mainly rain to the south. Lows 30-38. Wind NE to E 5-15 MPH, higher gusts in coastal areas.
SATURDAY: Overcast. Precipitation very gradually tapering off west to east with snow/mix/rain line moving back to the south with time. Highs 34-41. Wind NE to N 10-20 MPH with gusts to 30 MPH inland, 20-30 MPH with gusts 40 MPH or greater coastal areas.
SUNDAY: Variably cloudy. Chance of a few rain/snow showers. Lows 30-38. Highs 38-45.
MONDAY: Sunny start, cloudy finish. Lows 28-35. Highs 44-51.
TUESDAY: Cloudy. Rain and possible sleet arriving. Lows 25-32. Highs 35-42.

DAYS 6-10 (APRIL 5-9)
Another period of unsettled weather April 6-8 which may include some mix/frozen as well as rain. Temperatures below normal.

DAYS 11-15 (APRIL 10-14)
A break in the active pattern as it turns drier but temperatures remain mostly below to near normal.

Friday Forecast (Preliminary)

7:29AM

DAYS 1-5 (MARCH 31-APRIL 4)
This is a preliminary post and will be followed later today but an updated one. For this post, there are not many changes being made except to shift the frozen rain/mix/snow line a little further south and tweak amounts accordingly. So, today still expecting precipitation to move eastward into the region during the day in a couple batches, fighting dry air, but with periods of snow, which will have difficulty accumulating when it falls as is typical for spring daytime snow. Most of this will occur in central MA and southwestern NH with a lighter mix/rain would likely occur in southern MA/CT/RI. Later in the day and into the evening a more solid area of precipitation is likely to move in from west to east, peaking during the overnight hours. During these hours is when the position and movement of the rain/mix/snow areas are most critical as this is when most of the snow accumulation would occur. It continues to be most likely that the most significant snow accumulation will occur away from the immediate coast and favor the higher elevations especially from central MA into southwestern NH, but this does not eliminate the possibility of significant accumulation elsewhere. Still going with colder scenario overall with the rain / narrow band of sleet / snow line moving up into the Mass Pike zone with areas to the south mainly rain for the heaviest precipitation and areas to the north staying as mainly snow. During Saturday as precipitation gradually lightens then diminishes from west to east, colder air will push this line back to the south when most of the accumulation to the south of Boston may occur. Current call on total snow accumulation: Under 2 inches South Coast including Cape Cod, southern RI, and southern CT, 2-4 inches northeastern CT, northern RI, and nearby southern MA eastward to the South Shore up to about the Mass Pike, 4 to 8 inches just north of the Mass Pike to northeastern MA and NH Seacoast with the lower amounts favoring the coast from Boston to Cape Ann, and 8 inches or more north central MA into interior southern NH. Also looking for quite a bit of wind as the storm intensifies offshore Saturday with some minor coastal flooding at the time of the mid afternoon high tide. A weak disturbance will bring some cloudiness and possibly a passing rain/snow shower Sunday. High pressure moves in Monday with dry but chilly weather for the Red Sox home opener. But the continued active pattern allows the next storm to be here Tuesday with what looks like mainly rain but possibly some sleet.
TODAY: Overcast. Periods of snow except mix/rain southern MA/CT/RI. Highs 34-40. Wind NE 5-15 MPH.
TONIGHT: Overcast. Snow except rain near South Coast then mix/change line advancing north into areas mentioned above. Lows 30-38. Wind NE to E 5-15 MPH, higher gusts in coastal areas.
SATURDAY: Overcast. Precipitation very gradually tapering off west to east with snow/mix/rain line moving back to the south with time. Highs 34-41. Wind NE to N 10-20 MPH with gusts to 30 MPH inland, 20-30 MPH with gusts 40 MPH or greater coastal areas.
SUNDAY: Variably cloudy. Chance of a few rain/snow showers. Lows 30-38. Highs 38-45.
MONDAY: Sunny start, cloudy finish. Lows 28-35. Highs 44-51.
TUESDAY: Cloudy. Rain and possible sleet arriving. Lows 25-32. Highs 35-42.

DAYS 6-10 (APRIL 5-9)
Another period of unsettled weather April 6-8 which may include some mix/frozen as well as rain. Temperatures below normal.

DAYS 11-15 (APRIL 10-14)
A break in the active pattern as it turns drier but temperatures remain mostly below to near normal.

Thursday Forecast

2:31AM

DAYS 1-5 (MARCH 30-APRIL 3)
A very nice day often precedes the arrival of a storm, and that will be the case today as high pressure dominates with plenty of sunshine. The March Lion will bring southern New England a storm of rain/mix/snow to end the month and linger into the opening hours of April – not really atypical of this time of year, and only ironically on the 20th anniversary of the much larger and more impacting “April Fools Storm” of 1997. With this system just a day away from arrival, it is now time to try to pin down some details. What I do know is that low pressure will approach from the west and track eastward, passing just south of New England, spreading a large shield of precipitation across the region during Friday, peaking Friday night, and lingering into Saturday. The critical part of the forecast will be the position of a rain/snow line during the event, as well as whether or not enough warm air gets in aloft to result in sleet rather than snow for a portion of the storm. Also, a strip of freezing rain needs to be considered as temperatures may be warm enough aloft for rain and cold enough at the surface for it to freeze. I don’t think this will occur over a widespread area, however. This is how I think it plays out: Friday, precipitation moves eastward during the day in a couple batches, fighting dry air, but with periods of snow, which will have difficulty accumulating when it falls as is typical for spring daytime snow. Lighter mix/rain would likely occur in southern MA/CT/RI. Later in the day and into the evening a more solid area of precipitation is likely to move in from west to east, peaking during the overnight hours. During these hours is when the position and movement of the rain/mix/snow areas are most critical as this is when most of the snow accumulation would occur. It continues to be most likely that the most significant snow accumulation will occur away from the immediate coast and favor the higher elevations especially from central MA into southwestern NH, but this does not eliminate the possibility of significant accumulation elsewhere. For now I am going with a slightly colder scenario with a rain/snow line and a narrow band of sleet moving into eastern MA and Seacoast NH to about I-95 and in most areas south of the Mass Pike (I-90) with a tendency for this to happen more quickly in valley areas and more slowly in higher elevations. Where a changeover occurs except a narrow band of sleet and also some freezing rain favoring the southern higher elevations of central MA. During Saturday, the rain/mix/snow line will waver around as precipitation gradually tapers off from west to east, finally becoming mostly patchy light rain/drizzle with a little mix to the north. Current call on total snow accumulation: Under 1 inch South Coast and most of southeastern MA, 1-3 inches NH Seacoast to Cape Ann MA to Boston to Providence westward to Hartford, 3-6 inches from just west of I-95 to near I-495 in northeastern MA down the I-95 belt to I-90 then westward along I-90, 6-10 inches central MA into interior southern NH with higher amounts possible in highest elevations. Some adjustments may still be made to this forecast! A weak disturbance will bring some cloudiness and possibly a passing rain/snow shower Sunday. High pressure moves in Monday with nice weather, and combined with afternoon opening day baseball at Fenway Park will make the recently-departed storm seem like a distant memory. Forecast details…

If you’re looking for details on the snow/mix/rain threat for Friday and Saturday you’re come to the right place, and the wrong place. I’ll tell you what I think may happen, but you won’t get snowfall numbers from me until at least later today in comments and more likely tomorrow morning on the new entry. Why? Because I don’t know yet. First, let’s back up to today, which starts cloudy and damp but dries out as a north wind develops behind departing low pressure. Clouds will remain dominant but should start giving it up to more sun eventually. Thursday will be the “pick of the week” of you like fair weather as a narrow area of high pressure provides that. Low pressure approaches from the west Friday and will pass just south of New England Friday night and Saturday as it redevelops there. This will bring widespread precipitation including snow/mix/rain. Still working on details of how this system will impact this area specifically, but for now it looks like the greatest chance for accumulating snow will be Friday evening and night, away from the South Coast, and over higher elevations. Improvement is attempted on Sunday but may be thwarted by an additional disturbance bringing a chance of rain/snow showers to the area.
TODAY: Starting overcast with areas of fog. Breaking clouds, eventually more sun late especially west of Boston. Highs 45-52. Wind N increasing to 10-20 MPH and gusty.
TONIGHT: Partly cloudy to mostly clear. Lows 28-35. Wind NW 10-20 MPH, higher gusts.
THURSDAY: Mostly sunny. Lows 22-30. Highs 46-53.

SATURDAY: Overcast. Snow/mix/rain mainly early morning then mostly mix/rain tapering off to drizzle. Lows 30-37. Highs 37-44.
SUNDAY: Mostly cloudy. Chance of rain/snow showers. Lows 32-40. Highs 40-47.
