.SYNOPSIS...
A cold front will continue to push offshore tonight with gusty
northwest winds in its wake. High pressure crosses the area
Thursday through Friday setting the coldest night of the season
Thursday night. Temperatures moderate Saturday under fair skies.
A cut off low near the Mid Atlantic will migrate northward early
next week and will bring a chance for rain Sunday night into
Monday.

.NEAR TERM /THROUGH TONIGHT/...
A cold front is now pushing offshore with gusty northwest winds in
its wake through this evening. A cooler and drier airmass will work
into the area overnight while a subtle short wave crossing northern
Maine may trigger isolated rain or snow showers near the Canadian
Border through the first part of tonight. The cooler airmass
will bring temperatures down into the upper 20s across northern
zones and mid to low 30s across the interior. Southeast NH and
coastal Maine will see lows around 40 degrees. Winds will stay
elevated tonight and may inhibit frost formation. Sheltered
areas within active zones along the interior may still be able
to see some frost and have issued a Frost Advisory across these
zones.

&&

.SHORT TERM /THURSDAY THROUGH THURSDAY NIGHT/...
High pressure centered over the Great Lakes will gradually build in
through the day Thursday. A tight NNW gradient will bring gusty NW
winds up to 30 mph. Despite ample sunshine the cooler airmass will
limit highs to the 40s north to 50s south. Strong winds combined
with cooler air will bring windchills below freezing in the
mountains.

High pressure will crest over the region Thursday night setting up
efficient radiational cooling. This will likely be the coldest night
of the season with lows ranging from near 20 degrees across the
north to near 30 degrees across the south with widespread freezes
likely. Have issued a Freeze Watch for all remaining active
zones.

.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
Overview...

High pressure remains in place across New England through the
end of the week and into the weekend. Low pressure stalls south
of New England late this week, and slowly moves northward
through the weekend. Impacts from this system are possible by
early next week.

Details...

High pressure brings continued dry conditions for the end of
the week and into the weekend. Temperatures moderate on Friday
and Saturday, with high ranging from the low 60s across the
north to upper 60s along the coast by Saturday. Nighttime temps
remain cool, with a frost or freeze likely again Thursday night
away from the coastline.

By Sunday the low pressure center makes some northward progress
along the East Coast. An east-northeasterly wind develops along
the coast, with high clouds increasing through the day across
southern areas. This keeps temps a bit lower across southern
areas, giving generally low to mid 60s across the area, with
more sunshine across the north.

By early next week moisture makes northward progress into New
England. Just how far north and how quickly remains in question.
The GFS remains more progressive with more moisture reaching
the area by late Sunday and Monday. The Euro, it`s ensembles,
and AI models generally have less moisture and later northward
progress until the Tuesday-Wednesday timeframe, but are starting
to show signs of a northward trend with weaker blocking to the
north.

Currently POPs allow for the chance of rain starting Sunday
night and into early next week across southern and coastal
areas. Should the northward trends continue, these would need to
be raised, and coastal winds may also have to be monitored for
some stronger northeasterly gusts.

.AVIATION /18Z WEDNESDAY THROUGH MONDAY/...
Short Term...Northwest winds will gust around 20 kts through
sunset. Drier air moving in will allow for prevailing VFR
tonight and Thursday. VFR likely prevails Thursday night outside
of valley fog.

Long Term...VFR prevails at all terminals during the daytime
through Sunday. Nighttime valley fog is possible each night,
especially at LEB, HIE, and CON. Restrictions are then possible
by early next week, especially along the coast, as a coastal low
brings an increasing chance of rain.

&&

.MARINE...
Short Term...Gusty northwest winds will continue SCA conditions
tonight into Thursday afternoon. As high pressure builds in
from the west, winds will relax Thursday night.


Long Term...High pressure brings fair conditions to the waters
through early Sunday. Seas and winds build starting on Sunday as
a coastal low moves up the the Eastern Seaboard. SCA conditions
are possible by late Sunday, with gales possible across the
outer waters by Monday.
