Synopsis for massachusetts and rhode island coastal waters.. Rain continues into this evening for coastal waters before coming to an end around midnight. Showers linger overnight along with patchy areas of fog. Mainly dry Monday before another low emerges off the mid atlantic coast Wednesday, likely tracking well south of new england as it intensifies into a gale center. A ridge of high pressure then builds across new england Thursday.

Area Forecast Discussion National Weather Service Boston/Norton MA 201 AM EST Mon Dec 4 2023
SYNOPSIS
A drying trend overnight but areas of fog will persist. Mainly dry weather follows Monday with highs in the 40s to the lower 50s. We turn colder Tuesday and Wednesday with perhaps a brief period of rain/wet snow across eastern New England...but any amounts should be light. Milder temperatures return for next weekend with our next shot at widespread precipitation not until next Sunday and/or Monday.
NEAR TERM /UNTIL 6 AM THIS MORNING/
2 AM update...
Mid level short wave exiting NY state and moving into northern New England at 2 AM. The back edge of the rain shield associated with this feature is moving across eastern MA and will be offshore by 3 AM. Dry weather follows along with a wind shift to the NW. Although it's not an abrupt change in airmass, with abundant low level moisture lingering. Therefore areas of fog will develop toward daybreak.
SHORT TERM /6 AM THIS MORNING THROUGH 6 PM TUESDAY/
Key Points...
* Considerable cloudiness Mon but nothing more than a spot shower * Highs Mon in the 40s to the lower 50s...milder south of I-90
Monday...
Any lingering fog and drizzle across central and eastern New England will come to an end by mid morning. We will have light northwesterly flow behind the departing shortwave/low pressure system. Additional shortwave energy coupled with cold 500T will result in an abundance of clouds persisting. While we may see some peeks of sunshine...clouds will dominate. Airmass is not that cold though with 850T near -2C/-3C
However
weak northerly flow may keep the inversion somewhat in place across northern MA which may hold highs in the 40s
South of the MA Turnpike
feel there is a better chance areas get into the lower 50s.
Dry weather is pretty much on tap for Monday...but can not rule out a brief spot shower given upper level shortwave energy and cold pool aloft. T
Monday night...
Yet another piece of shortwave energy will be moving across the region Monday night
However
there is not much low level support for anything more than a scattered to broken deck of clouds and perhaps a brief spot rain/snow shower. Perhaps a bit better chance for a few rain/snow showers near daybreak towards the eastern MA coast with hints of an inverted trough trying to setup. The NAM seems to start this a bit earlier than most of the other guidance...so this might be delayed
Otherwise
generally dry Monday night with a scattered to broken deck of clouds and lows mainly in the 30s.
LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/
Highlights
* Trending colder Tuesday through Thursday
* Chance for some some nuisance snow across eastern MA/RI Tuesday night into Wednesday morning
* Trending warmer Friday into the weekend
Tuesday and Wednesday
Persistent northwest flow and low-level CAA will begin a cooling trend on Tuesday. 925 hPa temps fall to around -5 Celsius on Tuesday afternoon which will support surface temperatures in the upper 30s to low 40s Tuesday afternoon. Cooler air aloft will also support steep-lapse rates that will allow for substantial cloud cover on Tuesday, so expect more clouds than sun on Tuesday afternoon.
Tuesday night into Wednesday, mesoscale models are beginning to resolve an inverted trough feature associated with short-wave energy aloft. This feature is expected to be meandering somewhere off the east/southeast coast of southern New England Tuesday night through Wednesday. With temperatures falling to near freezing Wednesday morning, this feature may provide enough forcing to support a period of snow showers Tuesday night into Wednesday.
Accumulations would likely be minimal given marginal surface temperatures, but some accumulations up to an inch or two are in the cards if temperatures are cool enough. Won't get too deep into the weeds regarding details given the uncertainty at the time range, but Wednesday morning will be a period to pay attention to early next week. We should have a better idea as more mesoscale/hi-res model guidance becomes available over the 24 to 36 hours. The rest of Wednesday will feature shower chances tapering off from northwest to southeast during the afternoon. CAA continues to bring 925 hPa temps down below -5 Celsius. Thus, another raw afternoon with high temps likely confined to the 30s across the region.
Wednesday night and Thursday
The cooling trend is forecast to peak Wednesday night into Thursday morning with surface temps falling into the teens and low 20s pretty much region wide. The exception areas as always will be the coastal locations where the proximity to the relatively warmer ocean waters will allow for somewhat milder temperatures in the mid to upper 20s. Northwest flow will create a very dry air mass over the region on Thursday with PWATs less than 0.2 inches, thus expect more sun than clouds on Thursday afternoon. Chilly high temps again in the mid to upper 30s.
Thursday night through Saturday
A mid-level ridge axis builds east of southern New England Thursday night into Friday, this will allow return flow from the south to begin a warming trend. 925 hPa temps climb to around 0C on Friday afternoon which should support high temps in the low to mid 40s.
Strong low-level WAA continues into Saturday and Sunday with progressively warmer temps each day. Models are honing in on a robust low-pressure system that is likely to bring substantial precipitation to portions of the northeast late next weekend/early next week.Vague details at this time range, but this looks to be the next opportunity for a substantial precipitation event.
AVIATION /07Z MONDAY THROUGH FRIDAY/
Forecast Confidence Levels:
Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.
06z update...
Today...high confidence on trends, lower on exact timing.
Dry weather but widespread IFR at 06z, slowly trends upward early this morning, improving to VFR 12z to 15z from west to east. Dry weather this afternoon with VFR cloud bases. West winds increase 10-20 kt.
Tonight...high confidence.
VFR cloud bases with isolated sprinkles/flurries possible (10%-20%) 00z-06z. Otherwise, dry weather prevails. WNW winds 5-15 kt.
Tuesday...high confidence.
VFR cloud bases, except MVFR for the outer Cape with 15-25% chance of light rain/snow showers. N-NW winds 10-15 kt.
KBOS Terminal...High confidence in TAF trends, lower on exact timing. Improving to VFR between 12z-15z, then VFR cloud bases remainder of the day.
KBDL Terminal...High confidence in TAF trends, lower on exact timing. Improving to VFR between 11z-14z, then VFR cloud bases into the afternoon.
Outlook /Tuesday Night through Friday/...
Tuesday: Mainly VFR, with local MVFR possible. Breezy.
Tuesday Night: Mainly VFR, with areas MVFR possible. Chance RA, slight chance SN.
Wednesday: Mainly VFR, with areas MVFR possible. Breezy. Chance RA, slight chance SN.
Wednesday Night through Thursday: VFR. Breezy.
Thursday Night through Friday: VFR.
MARINE
Forecaster Confidence Levels:
Low - less than 30 percent.
Medium - 30 to 60 percent.
High - greater than 60 percent.
Tonight...High Confidence.
Small craft headlines continue tonight for E wind gusts of 20 to 30 knots this evening. These winds should diminish overnight as the shortwave departs...but may see another brief round of sca wind gusts as winds shift to the west overnight across our southern waters. Seas of 3 to 6 feet continue across the open waters & fog will also reduce vsbys for mariners.
Monday and Monday night...High Confidence.
Winds shift to more of a NNW direction as low pressure tracks across across northern New England. Gradient weak enough to generally keep wind gusts below SCA thresholds most of the time...but some 20+ knot gusts are expected. Lingering swell though will keep seas in the 3 to 5 foot range across our outer-waters...so still need SCA headlines through Monday night for those locations.
Outlook /Tuesday Night through Friday/...
Tuesday: Winds less than 25 kt. Areas of seas approaching 5 ft.
Chance of rain.
Tuesday Night: Winds less than 25 kt. Chance of rain.
Wednesday: Winds less than 25 kt. Seas locally approaching 5 ft. Chance of rain.
Wednesday Night: Low risk for Small Craft Advisory winds with gusts up to 25 kt. Seas up to 5 ft. Slight chance of rain.
Thursday: Winds less than 25 kt. Seas locally approaching 5 ft.
Thursday Night through Friday: Winds less than 25 kt.
