Synopsis for massachusetts and rhode island coastal waters - Cold front sweeps across the waters today bringing scattered showers and perhaps a Thunderstorm or two. Winds will shift from the southwest to the west, eventually turning north, by tonight. Winds will gust to as high as 25 to 30kt on northerly flow into Thursday morning. High pressure again builds over the waters for late week with light winds. Low pressure brings rain chances and breezy winds by Tuesday.

SYNOPSIS
Showers and perhaps an isolated thunderstorm today with the passage of a cold front. Dry but cold overnight, which prompt a Freeze Watch for parts of Connecticut, Rhode Island, and southeast Massachusetts. More seasonable conditions develop for the weekend. Another chance for showers comes mid to late weekend then again late Mon or Tue.
NEAR TERM /UNTIL 6 PM THIS EVENING/
Highlights:
* Showers and perhaps an isolated weak thunderstorm through this afternoon with near seasonable temperatures.
Robust mid-level shortwave and surface cold front will bring sct'd light rain during the first-half of the day, followed by a secondary round of sct'd to iso'd convective showers this afternoon. Showers early this morning need to overcome surface dry air, we've watched the dewpoint/temperature depression decrease with some activity of light rain in far western Massachusetts. High-res models hint at the first round of precip between 13z-19z, then the secondary convective showers 19z-23z - all from west to east. SPC placed all of southern New England in general thunder this afternoon, no risk for severe.
But, given the flow aloft is between 25-35 knots, at best a convective shower could produce an iso'd gust between 30 and 40 mph. In general, QPF is a few hundredths of an inch to a tenth of an inch, though any convective showers could produce locally higher amounts up to a 0.25 inch.
Southwest winds this morning become westerly this afternoon behind the cold front, with gusts to 20 to 30 mph. Afternoon highs in the low 60s, slightly cooler at the immediate coast and higher terrain of northern/western Massachusetts.
SHORT TERM /6 PM THIS EVENING THROUGH 6 PM THURSDAY/
Highlights:
* Freeze Watch expanded for Wednesday night, and then potential elevated fire weather concerns on Thursday.
As advertised, the overnight hours will be rather cold. Clouds clear quickly as the cold front races off shore and PWATs fall. The wind direction shifts, west to north, advecting an unseasonably cold air mass over southern New England.
925mb temperatures range between -3C and -5C. As mentioned, the previous forecaster brought up a good point, there are two ways we can achieve unseasonably low overnight temperatures - one being traditional radiational cooling - second is to mix down the colder air aloft. Right now, most of the night looks to have a well mixed boundary layer with steady north wind. This will transport those colder temperatures aloft to the surface. By the end of the night, we could decouple for the last two or three hours - with clear sky cover this will help maintain and or lower the temperatures further. Overnight lows are in the low and middle 20s across northern Massachusetts, southern coast could have overnight lows in the upper 20s to low 30s. For temperatures, did us a blend of the forecast and the BC of the MAV. Cape Cod and Islands is tough, do think the SST will help to keep above freezing, but could be close. Just last night, MVY saw the temperature freefall into the upper 20s with calm wind and clear sky. During this update we expanded the Freeze Watch to southern Rhode Island and south coast of Massachusetts. We did omit the islands and Cape Cod. Day crew will need to evaluate guidance and decide whether to go with a freeze warning or frost advisory in the area where the frost/freeze program is active.
Heading into Thursday we are dry but noticeably cooler with highs only reaching into the middle 50s. A dry air mass settles over the region thanks to 1030mb high moving south out of Canada. Winds are northwest and less than 10 mph, possibly becoming more light and variable by late afternoon. Elevated fire weather concerns because of very low values of RH due to low dewpoint temperatures in the teens. Minimum values of RH are in the upper teens to upper 20s away from the coast.
LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/
Key Points...
* Dry weather through Saturday.
* Chance of showers Saturday night then again around Tuesday.
* Temperatures increase each day through Monday when some could see highs near 80.
Details...
Surface high pressure centered over New York Thursday night remains in control through Saturday, crossing New England on Friday.
Subsidence beneath the high and very little moisture in the column will lead to dry conditions and sunny skies each day through Saturday (though clouds will begin moving in to start the weekend).
Given the high pressure overhead winds will be light and variable.
Thus, we'll see a few nights of good radiational cooling with the typical cool spots dropping into the upper 20s to low 30s. By Friday the mid level ridge axis shifts over or just east of SNE with low/mid level winds backing to the SW bringing warm advection. 850 mb temps rise from -3C on Thursday to 0C on Friday and +3C by Saturday afternoon. This will translate to highs steadily increasing each day, into the mid to upper 60s in the interior by Saturday.
Areas along the south coast will be cooler (50s) thanks to onshore flow.
The dry pattern breaks down briefly for the second half of the weekend as a passing warm front will bring not only increasing cloudcover Saturday afternoon but the chance for widespread light showers Saturday night. It will be trailing behind a surface low which lifts into Canada; with little forcing and mid level ridging overhead, not expecting much out of these showers. A more substantial system looks to arrive with a shortwave on or around Tuesday. Something of note for the start of the week will be the very warm day on Monday (well into the 70s in the interior). The chance for a backdoor front to spoil things is looking less likely, though a seabreeze will likely keep those along the coast in the 60s. Meanwhile, the CT Valley may see temperature approaching 80F! The odds temps AOA 80F are between 40-50% per the EPS/GEFS ensemble guidance.
AVIATION /12Z WEDNESDAY THROUGH SUNDAY/
Forecast Confidence Levels:
Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.
Today...Moderate confidence.
VFR through 12z, MVFR conditions develop west to east as a cold front approaches the region with scattered rain showers between 14z and 18z. Localized IFR is possible. A second round of hit or miss showers 20z to 23z could contain isolated risk of thunder.
Southwest winds shift to the west behind the frontal passage mid day, winds gusting to as high as 20kt.
Tonight...High confidence.
Rapid clearing, becoming VFR from west to east behind the departing front. Wind shift to the north/northwest 5 to 10 knots, though could remain gusty with winds to 20 knots along the Cape and Islands.
Thursday...High confidence.
VFR. North/northwest winds 5 to 10 knots. Winds ease and direction becomes variable late afternoon.
KBOS TAF...Moderate confidence.
Cold frontal passage brings showers to the terminal between 15z-19z. Low risk for TSRA between 20-23Z this afternoon before rapid clearing. Winds are southwest this morning and west this afternoon behind the frontal passage. Winds eventually become north late tonight, winds will be greatest for coastal terminals, up to 25kt.
KBDL TAF...Moderate confidence.
Cold frontal passage brings showers to the terminal between 14z-18z. Winds are south/southwest this morning become west behind the front this afternoon, then north overnight. Low risk for TSRA between 20-23Z this afternoon before rapid clearing.
Outlook /Thursday Night through Sunday/...
Thursday Night through Friday Night: VFR.
Saturday: VFR. Breezy.
Saturday Night: Mainly VFR, with local MVFR possible. Breezy.
Chance SHRA.
Sunday: Mainly VFR, with areas MVFR possible. Breezy. Slight chance SHRA.
MARINE
Forecaster Confidence Levels:
Low - less than 30 percent.
Medium - 30 to 60 percent.

Today through Thursday...High Confidence.
Rain showers and an isolated thunderstorm with a cold front passage later today. Cold front will bring a wind shift from southwest to west/northwest this afternoon, then becoming northerly overnight.
Wind gusts increasing 25 to 30 knots and increasing seas to over 5 feet, this lead to a Small Craft Advisory through late Thursday morning. Surface high pressure comes down from Canada with easing winds and diminishing seas for Thursday afternoon.
Outlook /Thursday Night through Sunday/...
Thursday Night through Saturday: Winds less than 25 kt.
Saturday Night through Sunday: Winds less than 25 kt. Slight chance of rain showers.
