- Rain and thunderstorm chances return for the first half of next
  week. Seasonable temperatures continue.

.DISCUSSION...
KEY MESSAGE 1...Isolated showers and thunderstorms this afternoon. 
Drier conditions following today's cold front.

Satellite shows continued clearing over southern New England today, 
which has aided in the development of scattered showers and 
thunderstorms. As of the time of writing, the cold front is passing 
through western MA and CT based on latest observations towards the 
Berkshires and in north central CT. Ahead of the front, showers and 
thunderstorms have popped up across central MA, with an earlier 
round having gone through northern MA. These will continue to push 
eastward and will likely maintain their growth given the enhanced 
SBCAPE, MLCAPE, clearer skies, and warmer surface temperatures in 
the 80s with dew points climbing into the low 70s/upper 60s. Strong 
to damaging wind gusts remain a possibility given DCAPE values 
between 1000-1100 J/kg. These showers and thunderstorms should exit 
the region early tonight, generally around 8-9 PM. Some may linger a 
bit longer near the Cape and Islands, though.

As the cold front moves through the region today and tonight, winds 
will shift more NW, and drier air will move in with cooler 
temperatures. High pressure starts to build in from the west 
Thursday while an upper level trough moves over the northeast. Highs 
Thursday will reach the low to mid 80s given 925 mb temperatures 
around 16-18z. With high pressure building in, winds will slacken 
and seabreezes will likely develop tomorrow. Mostly clear skies and 
light to calm winds Thursday night will lend to radiational cooling 
as well, leading to lows dropping into the 50s.

KEY MESSAGE 2...Mainly dry with seasonable temperatures through the 
weekend. 

While the synoptic pattern will feature broad, weak troughing in the 
mid levels over the northeast, subsidence associated with a building 
surface high pressure center will keep things dry from Friday 
through at least Sunday. This, while said troughing pattern keeps 
seasonable temperatures around; 850 mb temps remain in the 11-13C 
range clear through early next week, which will lead to high 
temperatures in the upper 70s to low 80s each day. Behind today's 
cold front, dewpoints will drop into the 40s and low 50s through 
Sunday as well, making it feel less humid and more comfortable. 
Altogether this should be a fantastic stretch of weather for outdoor 
plans. 

KEY MESSAGE 3...Rain and thunderstorm chances return for the first 
half of next week. Seasonable temperatures continue. 

The pattern begins to break down around Monday with the mid level 
trough digging into the northeast with several disturbances rotating 
around the base of the trough inducing areas of surface low pressure 
which will stand the chance to bring us rain and thunderstorms as 
soon as Monday with the threat continuing much of next week. As 
mentioned previously, there is no big warm-up on the horizon.

.AVIATION /18Z WEDNESDAY THROUGH MONDAY/...
Forecaster Confidence Levels...

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

18Z Update... 

Rest of Today...Moderate confidence. 

Improvement to VFR continues this afternoon across much of the
region. IFR/MVFR may linger over the Cape and Islands a bit
longer than in other areas but should clear heading into
tonight. Isolated showers and thunderstorms remain a possibility
through this afternoon, and some are presently moving through
western MA eastward. These should remain isolated and scattered
in terms of coverage. Due to lower confidence on where exactly
these showers and storms will impact, mentions are mostly as 
PROB30s, with the exception of BDL where confidence is higher as
showers/storms were developing near the terminal at the time of
TAF issuance. SW winds 10-15 knots with gusts 20-25 kts. 

Tonight...High Confidence. 

Any afternoon SHRA/TSRA wanes after 00Z. Some SHRA may reach the
Cape and ACK later tonight after 00z, but are not expected to be
widespread. VFR. Winds shift to WNW/NW at 5-10 knots behind a 
passing cold front between 22-03Z.

Thursday...High confidence.

VFR. Winds light, mostly NNW/N. Winds may become more variable
later in the afternoon/evening inland. Seabreezes likely by 
15z-16z.

Thursday Night...High confidence.

VFR. Clearer with light to calm winds overnight, giving way to
possible radiational cooling.

KBOS Terminal...Moderate confidence in TAF. 

Lower confidence with the potential for showers/thunderstorms, 
mainly due to the isolated nature of showers/storms. Included a 
PROB30 for now to TSRA with the most likely timeframe being 
between 20-01Z.

KBDL Terminal...High confidence in TAF.

Outlook /Friday through Monday/...

Friday through Sunday Night: VFR. 

Monday: Mainly VFR, with local MVFR possible. Slight chance
SHRA.

&&

.MARINE...
Forecaster Confidence Levels...

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

Tonight through Thursday Night

Small Craft Advisories remain in effect for SW winds 10-20 kts
with gusts 25-30 kts and 6-10 foot seas for the outer coastal 
waters and southern waters. Highest waves are expected over the 
south coastal waters. Isolated showers and thunderstorms 
possible early tonight. 

A cold front crosses the waters tonight resulting in a wind 
shift to the NW. Winds and seas will slowly decrease overnight
across the northern waters. Seas will be the slower to decrease,
especially across the southern waters. High Surf Advisory
remains in effect for exposed southern coastlines through
Thursday given the elevated seas and the higher risk for rip
currents on Thursday given receding seas and residual swell.

Seas recede to 4 ft Thursday night with light winds over the
waters.

Outlook /Friday through Monday/...

Friday through Friday Night: Winds less than 25 kt. Seas
locally approaching 5 ft. 

Saturday through Saturday Night: Winds less than 25 kt. Areas
of seas approaching 5 ft. 

Sunday: Winds less than 25 kt. Seas locally approaching 5 ft. 

Sunday Night through Monday: Winds less than 25 kt. Slight
chance of rain showers.
