.SYNOPSIS...
Dry weather will continue through the rest of the week with warming
temperatures into the 70s. An approaching cold front may bring a
few brief showers late Friday night into early Saturday...followed
by plenty of sunshine and very pleasant high temperatures
Saturday and Sunday afternoons. An approaching cold front will
likely bring a round of showers sometime late Sunday night into
Monday...followed by mainly dry but cool/fall- like weather for
Tuesday and Wednesday.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
640 AM Update...
* Mix of clouds & sun today...highs in the lower to middle 70s
A deck of mid level cloudiness northwest of I-95 generally has
kept early morning temps in the 50 to 55 degree range.
Meanwhile...mainly clear skies across eastern MA/RI which has
allowed early morning temps to drop mainly into the 40s.
We do think that the broken deck of clouds across the interior
scour out to some degree by afternoon...so expect a mixture of
clouds and sunshine. Building ridge and SW flow will allow
temperatures to rebound handsomely by this afternoon, into the
low and mid 70s away from the immediate coastline.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM FRIDAY/...
Sprawling high remains in place overnight tonight into early Friday,
though southerly/southwesterly flow will support low to mid level
clouds along the south coast overnight tonight. Additionally, with
dewpoints climbing into the low and mid 50s, river valley fog is
likely across the CT River Valley as clearing skies and light winds
support healthy radiational cooling overnight.
Friday looks to be another mild day as 850mb temperatures peak
around 12C around 15Z before falling as approaching shortwave breaks
down mid level ridging by late afternoon. Do expect more sun than
clouds, but residual patchy cloud cover. Will note that guidance is
having trouble resolving exactly how widespread clouds will be,
which will likely impact just how warm temps are able to climb, but
anticipating another day with most localities in the 70s to round
out the week. Any precip associated with the aforementioned
shortwave look to hold off until after 00Z.
&&
.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
Key Points...
* A few brief showers possible late Fri night into early Sat
* Plenty of sunshine & very pleasant the rest of Sat into Sun
* Round of showers are on tap for late Sun night into Mon
* Mainly dry but cool/fall-like weather Tue-Wed with frost possible
Details...
Fri night and Sat...
A shortwave/weak cold front crosses the region late Fri night into
mid-morning Sat...which may be accompanied by a few brief showers.
Otherwise...drier air working in from the north should allow plenty
of sunshine to develop by Sat afternoon. 850T near +8C should allow
high temps to reach the lower to middle 70s in many locations.
Sat night and Sun...
Weak mid level ridge axis approaches from the west Sat night and
crosses the region Sun. This will result in dry/tranquil weather.
Good radiational cooling should allow Sat night low temps to bottom
out mainly in the 40s Sat night. Plenty of sunshine on Sun...so
highs will recover into the upper 60s to the lower 70s.
Late Sun night into Mon...
The next shortwave/cold front will be approaching from the west. A
modest southwest LLJ/Pwat plume ahead of this cold front should
result in a period of showers sometime late Sun night into Mon. So
it does appear that the upcoming work week will get off to a wet
start.
Tue and Wed...
A closed amplifying closed low over Quebec will carve out a deep
trough across the northeast. So while Tue and Wed will mainly be
dry...it will bring our first taste of fall-like weather to the
region. High temps will probably be held in the upper 50s across the
high terrain...to the lower to middle 60s elsewhere. Overnight low
temps Tue night will likely drop into the 30s across much of the
region and some frost will be possible. Even the Urban Heat Islands
of Boston and Providence should see overnight lows bottom out in the
lower to middle 40s.

.AVIATION /12Z THURSDAY THROUGH MONDAY/...
Forecast Confidence Levels:
Low - less than 30 percent.
Moderate - 30 to 60 percent.

12z TAF Update...
Today...High Confidence.
Localized patchy ground fog across eastern MA/RI will dissipate
by mid-morning. Otherwise...VFR conditions today with SW winds
around 5-10 knots but localized sea breezes will likely develop
by afternoon along the very immediate eastern MA coast.
Tonight...Moderate confidence.
Mainly VFR with pockets of IFR to LIFR possible due to
radiation fog across the CT River Valley (BAF/BDL/ORE) as well
the typical low-lying spots across eastern MA.
Friday... High Confidence
Any fog formation overnight will dissipate by mid morning
leading to VFR across the region. Afternoon cloud development
with cigs around 5000ft likely. Light winds from the S/SW,
though SE at Nantucket.
BOS TAF...High confidence in TAF.
VFR. We do expect a sea breeze to kick in the 14z to 16z time
frame.
BDL TAF...High confidence in TAF.
VFR conditions today and tonight, although localized patches of
ground fog may flirt with terminal overnight.
