Synopsis
A warm front will bring showers late today and tonight. This
will set the stage for near record high temperatures Tuesday,
and especially Wednesday, so long as enough sunshine is
realized. Lower temperatures work into the region Thursday into
this weekend, but still expecting them to remain above normal.

Greatest risk for unsettled weather will be sometime Friday
into next weekend.

Near term through tonight
Increasing clouds the rest of this afternoon. Persistent south
winds led to some stratocumulus clouds across portions of ri
and southeast ma. These clouds pretty much developed in place,
but will likely persist until the clouds moving in from the west
arrive. Temperatures should rise much more slowly the rest of
today.

Regional radar showing an area of showers moving across eastern
ny state. These showers should first cross the berkshires about
2 pm, reaching the worcester hills between 3-5 pm, and greater
boston between 5-7 pm. This is not a solid area of rain, so
coverage is still expected to be hit-and-miss to some extent
until later this evening. Risk for showers should gradually
diminish after midnight.

A warm front should move north of our region overnight. The
persistent south winds should mean nearly steady to slowly
rising temperatures through the night, too. Patchy fog is
expected, which could become locally dense toward the south
coast with the flow right off the ocean.

Short term Tuesday through Tuesday night
Tuesday...

a few showers and patchy fog may linger along south coastal
areas early, then should push offshore by around midday.

However, clouds will likely linger across most areas through the
day.

The big question will be whether the clouds will dissipate
during the midday and afternoon hours across the interior. If
the clouds do break more than currently forecast, max
temperatures will likely be higher than current forecast, too.

Tuesday night...

anomalous southwest flow will continue across southern new
england. Low temperatures expected to be about 10 degrees above
the normal high temperature for this time of year. Still
thinking some low clouds and fog are possible, especially near
the CAPE islands with high dewpoint air moving over the
relatively cool ocean.

Long term Wednesday through Sunday
Highlights...

* Wednesday: near all time february record highs might be
approached if enough sunshine is realized
* cooler Thu Fri into next weekend but temps still above normal
* unsettled weather possible sometime Friday into next weekend
with ptype favoring rain although a bit of ice snow can not be
ruled out
details...

Wednesday...

anomalous upper level ridge of 594 decameters off the southeast
coast will pump an incredibly mild airmass into our region for
late february standards. This will result in 850t rising to
between +12c and +14c. Given southwest flow... High temperatures
will climb well into the 60s to lower 70s inland from the
cooling marine influence of the southeast new england coast. If
this ends up being the case... Record highs would be broken and
near all time february record high temperatures would be
challenged. The one fly in the ointment is if we are jammed up
in a bunch of low clouds. NAM soundings suggests this as a
possibility... But often southwest flow is able to allow for
these to break up. However... If the low clouds remain in place
high temps would be cooler than currently forecast. Something
later shifts will have to monitor closely.

Wednesday night and Thursday...

while the southeast upper level ridge will remain in place,
1040+ mb surface high pressure system will approach from the
west and force a cold front south of the region Wed night thu.

The result will be significantly cooler temperatures Thursday
with high temperatures mainly in the 40s. At this time... The
bulk of the period looks dry but we can not rule out a period of
mainly ana frontal showers which are depicted in some of the
gefs eps ensemble members.

Friday through Sunday... .

Low confidence forecast particularly with timing, but the
potential exists for a couple rounds of unsettled weather
Friday into next weekend. Certainly not expecting the entire
period to be a washout... Just impossible to try to time
individual shortwaves this far out. The southeast ridge remains
pretty strong... So ptype favors mainly rain. However... If a
couple canadian high pressure systems are slower to retreat it
could be marginally cold enough to support a bit of snow ice.

Aviation 18z Monday through Saturday
Forecaster confidence levels...

low - less than 30 percent.

Moderate - 30 to 60 percent.

High - greater than 60 percent.

Short term through Tuesday night ... High confidence in trends.

Moderate confidence in timing.

Through 00z... MainlyVFR. Some MVFR CIGS vsbys should develop
from west to east in scattered showers after 19z.

Tonight... Areas of MVFR CIGS vsbys in scattered -shra and
patchy fog. Local ifr possible toward the south coast, including
the CAPE and islands. S winds gust up to 20 kt across CAPE cod
and the islands.

Tuesday... Mix of conditions. MVFR vsbys MVFR-ifr CIGS in
scattered -shra and patchy fog early, improving toVFR.

However, MVFR to local ifr conditions may linger along the s
coast through early afternoon.

Tuesday night... Areas MVFR ifr conditions should redevelop in
low clouds and patchy fog. Breezy. Slight chance shra toward the
s coast.

Kbos terminal... Moderate confidence in taf.

Kbdl terminal... Moderate confidence in taf.

Outlook Wednesday through Friday ... Moderate confidence.

Wednesday: mainlyVFR, with local ifr possible. Breezy. Slight
chance shra.

Wednesday night through Thursday: mainlyVFR, with areas MVFR
possible. Breezy. Chance shra.

Thursday night:VFR. Breezy.

Friday: mainlyVFR, with areas MVFR possible. Breezy. Chance
ra, slight chance fzra.

Marine
Forecaster confidence levels...

low - less than 30 percent.

Moderate - 30 to 60 percent.

High - greater than 60 percent.

Short term through Tuesday night ... High confidence.

Wind gusts not quite reaching 25 kt early this afternoon. So
will give some thought to canceling some of the small craft
advisories early. Need to evaluate the sea state over the next
hour or so, first.

Rough seas still expected to develop across the ocean-exposed
waters with the arrival of southerly swells. Will need to
continue the small craft advisories across those waters. Scattered
showers and patchy fog will bring reduced visibility tonight,
then should improve on the eastern waters Tuesday. Reduced
visibility lingers Tuesday into Tuesday night on the southern
waters in patchy fog and isolated showers.

Outlook Wednesday through Friday ... Moderate to high
Wednesday: winds less than 25 kt. Areas of rough seas. Slight
chance of rain showers, patchy fog. Local visibility 1 to 3 nm.

Wednesday night: winds less than 25 kt. Local rough seas.

Chance of rain showers.

Thursday: winds less than 25 kt. Seas locally approaching 5 ft.

Chance of rain showers.

Thursday night: winds less than 25 kt.

Friday: winds less than 25 kt. Seas locally approaching 5 ft.

Chance of rain.
