Synopsis
Low pressure off the coast will exit into the maritimes
tonight. An arctic cold front will drop south through the region
on Wednesday. A strong northwest flow follows the front
Wednesday night and Thursday with record cold temperatures.

High pressure will build in from the west Thursday night and
will crest over the region on Friday. High pressure will shift
offshore Friday night and will hold there through Saturday. A
warm front will approach from the south Saturday night and
Sunday.

Near term through tonight
Low pres in the gulf of me will exit into the maritimes tonight
bringing an end to the snow across the region from southwest to
northeast. Need to continue all winter wx advisories for the
rest of the aftn as steady light snow continues across the
advisory areas with some additional light accumulations
occurring. Tonight only partial clearing expected. Winds will be
light but with clouds over most areas temps will remain in the
20s except teens in the mtns.

Short term Wednesday through Wednesday night
A vigorous short wave with an associated arctic cold front will
move through the region Wed afternoon. Expect brief snow
squalls with this fropa. Behind the arctic front, bitter cold
air follows and gusty northwest winds. Record cold temps will be
on the way with this air mass. With fresh snow cover and some
climo weighting, models likely to warm with temps.

Long term Thursday through Tuesday
Thanksgiving day will feature plenty of wind and temperatures well
below normal for this time of year. Looking like a mix of sun
and clouds with highs generally in the single numbers in the
north and lower to mid teens in the south. Wind chill values in
the north will likely require wind chill advisories... Especially
during the morning. Latest guidance giving wind chill values of
-10 to -20 for a good portion of the day. Weak trough dropping
south from canada may produce a few afternoon flurries in far
northeast zones but the majority of the forecast area should see
a dry day.

Wind will subside Thursday night as high pressure continues to build
in from the west. Very dry airmass and clearing skies will
allow for good radiational cooling... But lingering northwest
gradient may help to keep temps from falling as far as they
could. Readings by Friday morning will be fairly uniform across
the region ranging from 5 below north to 5 above south.

High pressure willl crest over the region on Friday before shifting
offshore with mostly sunny skies and light winds. Despite the
sun high temperatures will only reach the mid teens north and
lower to mid 20s south.

Looking for variable high clouds Friday night as high pressure holds
offshore. Once again overnight lows will bottom out well below
normal with lows in the single numbers in northern and central
zones and lower to mid teens south.

High pressure will continue to slide east on Saturday as the next
shortwave approaches from the west. Expect increasing high and
mid level clouds during the day as warmer air returns to the
region. Should see a dry day with just a chance of a shower in
the connecticut valley toward evening. Highs on Saturday will
finally get back to near normal... Ranging through the 30s from
north to south.

Warm front will swing into the region from the southwest Saturday
night bringing a variety of precipitation to the region.

Temperatures will fall back below freezing and with warmer air
aloft will likely see freezing rain and sleet in a good portion
of interior sections of maine and new hampshire. With rain or a
mix in southern and coastal zones. Lows will likely be reached
in the evening before slowly rising overnight.

Warm front will push east of the region on Sunday with
precipitation exiting eastern zones during the morning hours.

Looking for skies to become at least partly sunny with highs
ranging from the mid 30s north to the mid 40s south.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
