.SYNOPSIS...
A cold front will push offshore this morning. High pressure will
build in from the northwest today and tonight then crest over the
area Saturday into Saturday night. High pressure will move away to
the east Sunday into Monday. Weak low pressure will cross the area
Monday night followed by a cold front on Tuesday.
&&
.NEAR TERM /THROUGH SATURDAY/...
Today...Cold front has moved offshore as of 7am, and any
isolated showers have dissipated. Breezy and not as warm today,
with an especially noticeable drop in temperatures over the
north compared to yesterday. Much drier air as well. Highs
ranging from around 60 in the north to the low 70s near the
coast. Mostly sunny skies.
Tonight...
Clear and cool. Issued a freeze warning for far N/NW areas and
frost advisory a bit further south. Think that areas from
Lincoln and Bangor S/E should stay frost-free tonight. Still a
bit of a pressure gradient over the area as the high pressure
will still be a bit to the west, so temperatures won`t reach
their full radiational cooling potential, especially in eastern
portions of the area. The next night, Saturday night, looks
like the coolest night for most places.
Saturday...
Sunny and still a bit breezy from the W/NW, but a bit less
breezy than Friday. Highs in the low to mid 60s with very dry
air.
&&
.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY/...
High pressure cresting over the area Saturday night will bring a
clear and very cold night. A freeze will be likely over the
northwest and frost is possible in any of the inland valleys as far
south as the Piscataquis and central Penobscot valleys. Steam fog
will likely shroud the rivers late at night into early Sunday
morning.
High pressure will begin to slowly slide east of the area Sunday as
a light return southwesterly breeze brings a little moderation in
temperatures. Highs under a sunny sky should reach the mid to upper
60s inland. High pressure will continue to move away to the east
Sunday night. This will bring a clear to partly cloudy night and not
nearly as cold as Saturday night with lows generally in the low to
mid 40s.
High pressure continuing to move away to the east on Monday will
result in a southwesterly return flow persisting. This will bring a
warmer day as inland highs make a return for 70.
&&
.LONG TERM /MONDAY NIGHT THROUGH THURSDAY/...
Our focus Monday night will be on a weak frontal system approaching
from the west supported by a very open upper level shortwave moving
in from the northern Great Lakes. Most of the forecast guidance is
currently showing a broken band of light showers moving across the
area as the low and accompanying cold front push through late Monday
night into Tuesday morning. The GFS is bringing less than a tenth of
an inch of rain while the ECMWF is offering closer to a quarter inch
of rain. One feature of interest is a small subtropical low off the
Mid-Atlantic coast. This system will likely pass well southeast of
our area but could feed a little additional moisture in if it comes
close enough.
Any lingering showers will push away to the southeast Tuesday night
followed by a new area of high pressure building down from Central
Canada on Wednesday. This will bring a return of mostly sunny and
dry weather Wednesday, Thursday and Friday.
Another shortwave, and broken band of showers, similar to the one at
the beginning of the week, may move in Friday night into Saturday
possibly bringing some patchy light rain to the area for the start
of the weekend.
High pressure returns next Sunday with dry weather.

5 ft Wednesday in response to subtropical low pressure offshore.
Otherwise, wind and seas should remain below SCA this coming week
