SYNOPSIS
Wednesday brings scattered showers and a thunderstorm or two as a cold front sweeps across the region. Very chilly Thursday morning with a Freeze Watch in effect. More seasonable conditions develop for the weekend. Another chance for showers comes mid to late weekend.

NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/
Dry and tranquil conditions persist this evening into much of the overnight hours. Low pressure well to our south will continue to filter some high clouds across southeastern MA and the Islands as high clouds stream in from the west ahead of an approaching cold front.

Winds from the south overnight advecting increased moisture over southern New England, combined with increasing cloud cover will keep temperatures considerable warmer than the last few nights, with lows generally ranging from the upper 30s to low 40s. Rain showers associated with aforementioned cold front may begin to push into western MA and CT by daybreak, but expecting dry conditions through the night for most.

Not expecting to decouple overnight in most locations which will preclude any radiation fog formation, but winds may slacken just enough by daybreak for some patchy advection fog to form across the Cape and Islands.

SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/
Cold front sweeps across southern New England during the daylight hours of tomorrow as trailing shortwave follows suit late afternoon/ early evening. Expecting two rounds of potential precipitation tomorrow, the first between 12-18Z with katafrontal showers tapping into SWerly flow enhanced PWATs, between 3/4 and 1". These showers are not expected to bring significant precipitation to the region, perhaps a tenth of an inch in any locality.

The second round of showers comes, at least as defined by the CAMs, as a very "stubby" line of potentially convective showers initiate by the trailing shortwave aloft between 18-23Z. CAMs remain varied both in the position and geographic spread of these isolated to scattered convective showers, but all 5 of the main HRRR members derive their existence tomorrow afternoon. Any convection will remain elevated, and sub severe. Surface CAPE will be near zero as cold air rushes in on W/NW flow, but breaks of sunshine during the PM hours will allow a few hundred joules of MUCape to develop above the surface inversion. All in all, expecting a few rumbles of thunder, but confidence is rather low in who will see a passing thundershower. At present, our best guess is somewhere in central/eastern MA or in southeastern MA/RI as the shortwave pivots east. Given the potential for convective showers, a few localized rain totals in excess of 0.25" are possible.

Conditions clear very quickly after sunset across the area as winds shift to the north overnight. Expected a very chilly night across southern New England, but there are two scenarios as to how we may achieve our morning lows. First, in a situation where we are unable to decouple and radiate, anomolously cold air aloft, for late April, with 925mb temps as cold as -5C, will partially mix to the surface, which will derive lows in the mid 20s to low 30s region wide. The second scenario, and perhaps the less likely scenario, is if we are able to completely decouple overnight, which would yield radiating under clear skies to dewpoints, which will be dismal in the mid 10s to 20s. In reality, we may see somewhat of a mix of these solutions, with the best chance for a period of slack winds across the far interior of MA. Given uncertainty in the potential for radiational cooling, utilize rather "middle of the road" guidance, the MAV, depicting temperatures dropping to the low 20s in far NW MA and mid to upper 20s outside of urban centers. Given the potential for widespread temperatures in the mid 20s, we have hoisted a Freeze Watch for portions of Connecticut, northern RI, and interior SE MA where the frost/freeze program is now active. With that said, the potential for a widespread freeze is stronger across the interior, but because the frost/freeze program does not start in these locations until May 1st, or later, based on the climatological last freeze, there is no Freeze Watch in effect. Winds are expected to stay high enough along the immediate coastline to preclude a hard freeze. Will note, given the potential for a breeze overnight, this is a likely a "freeze or nothing" scenario, with frost unable to form given the winds.

LONG TERM /THURSDAY THROUGH TUESDAY/
Key Points...

* Dry Thu through Sat. Chance of showers Sat night and Sun.

* Cool Thu, then milder Fri into Mon. Turning cooler Tue.

* Chance of showers Sat night and Sun. Another round of showers Mon night into Tue.

Details...

Latest guidance suite was in rather good synoptic agreement into this weekend. Then some differences start to appear, but nothing profoundly unusual for this forecast time range.

High pressure will remain in control of our weather Thursday into Saturday. Temperatures will be modulated based on our relative location to this high center. With the high pressure moving overhead Thursday, that should be our coolest day of this stretch. AS this high pressure moves offshore into this weekend, we begin a warm up to above normal temperatures. Some question on whether southerly flow will be strong enough to completely preclude a seabreeze Monday. As high as temperatures are expected to be, seabreezes are likely, which would mean a significant temperature gradient between the coast and farther inland.

A passing warm front should provide a risk for showers some time late Saturday into Sunday. Monday is looking mostly dry, with a stalled front to our north. Increasing risk for showers some time late Monday into Tuesday as a cold front approaches from the west.
Stayed close to the NBM timing for now, but do not have much confidence in the timing.

AVIATION /21Z TUESDAY THROUGH SUNDAY/
Forecast Confidence Levels:

Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.

Through tonight... High Confidence

VFR through 09Z Wednesday with MVFR cigs possible across western terminals through 12Z. Rain showers develop ahead of advancing cold front during the pre dawn hours and may creep east into BAF/BDL prior to 12Z, but terminals farther east will remain dry through the period. ESE/SE winds this afternoon become south after 22Z. Winds shift further to the SW by sunrise. Winds generally 10 to as high as 15kt, though some gusts to 20kt possible along the south coast through sunset tonight.

Wednesday...High confidence.

Generally low end VFR to MVFR, with lower cigs in showers between 12-20Z. Localized IFR possible. Rain will trend showery over stratiform in first surge of cold frontal precipitation.

A secondary round of widely scattered showers will develop after 20Z and may contain isolated TSRA. Uncertainty remains too high to include a PROB30 or prevailing TSRA group at any terminal, but the best chance for any sort of thunderstorm remains between 20-23Z.

Southwest winds shift to the west behind the frontal passage mid day, winds gusting to as high as 20kt.

Wednesday night... High Confidence.

Rapid clearing expected from west to east, widespread VFR with nearly clear skies. Winds shift to the north and will range between 5 and 10kt.

KBOS TAF...High Confidence Cold frontal passage brings showers to the terminal between 10-20Z Wednesday. Low risk for TSRA between 20-23Z before rapid clearing occurs. Winds ESE this afternoon become SW overnight and W behind the frontal passage tomorrow afternoon. Winds eventually become N by late Wednesday night. Uncertainty in strength of winds on Wed night, but winds will be greatest for coastal terminals, up to 25kt.

KBDL TAF...High Confidence Cold frontal passage brings showers to the terminal between 10-20Z Wednesday. Winds become SW overnight and W behind the frontal passage tomorrow afternoon. Winds eventually become N by late Wednesday night.

Outlook /Thursday through Sunday/...

Thursday through Friday Night: VFR.

Saturday: VFR. Breezy. Slight chance SHRA.

Saturday Night: Mainly VFR, with local IFR possible. Breezy.
Chance SHRA.

Sunday: Mainly VFR, with local IFR possible. Breezy. Slight chance SHRA.

MARINE
Forecaster Confidence Levels:

Low - less than 30 percent.
Medium - 30 to 60 percent.
High - greater than 60 percent.

Tonight...

Tranquil conditions persist for the waters with southeasterly winds becoming more southwest overnight. Gusts to 25kt diminish slightly overnight but resurges to around 20kt by early AM.

Wednesday and Wednesday night...

Cold front sweeps across the waters Wednesday afternoon bringing showers and a wind shift from the SW to the W. Low chance for a thunderstorm across the inner waters late Wednesday afternoon/early evening but would be localized. Winds further shift to the north overnight Wednesday, with gusts in excess of 25kt possible across the northeastern waters.

A small craft advisory is in effect for the outer and eastern waters from 12Z Wednesday to 12Z Thursday for seas in excess of 5 feet and gusts in excess of 25kt.

Outlook /Thursday through Sunday/...

Thursday: Winds less than 25 kt. Areas of seas approaching 5 ft.

Thursday Night through Saturday: Winds less than 25 kt.

Saturday Night: Winds less than 25 kt. Slight chance of rain showers.

Sunday: Low risk for Small Craft Advisory winds with gusts up to 20 kt. Areas of seas approaching 5 ft. Slight chance of rain showers.

FIRE WEATHER
Thursday...Potential Elevated Fire Weather Concerns.

Fire weather may again be a concern on Thursday depending on how much rain falls on Wednesday, and how quickly winds subside as high pressure builds in by Thursday mid-day. Further shifts will need to evaluate this risk based on observations and model guidance.

BOX WATCHES/WARNINGS/ADVISORIES
CT...Freeze Watch from late Wednesday night through Thursday morning for CTZ002>004.
MA...Freeze Watch from late Wednesday night through Thursday morning for MAZ017-018.
RI...Freeze Watch from late Wednesday night through Thursday morning for RIZ001>004.
MARINE...Small Craft Advisory from 8 AM Wednesday to 8 AM EDT Thursday for ANZ231-250-251-254>256.
