High pressure will cross the region overnight through
Thursday. Low pressure will approach from the southwest 
Thursday night into Friday then track into the Maritimes
Friday night. Cold with scattered snow showers this weekend.

High pressure will build toward the region overnight. Wind gusts
of 30 to 35 mph will persist this evening, with decreasing 
winds overnight. The winds could cause patchy blowing snow across
northern areas this evening. Otherwise, expect partly cloudy
skies with scattered flurries across the north and mountains
early tonight with mostly clear skies overnight. Mostly clear
skies are expected across the remainder of the forecast area 
tonight. Overnight low temperatures will generally range 
through the single digits north, to 5 to 10 interior Downeast
with 10 to 15 along the Downeast coast. Have updated the
forecast to adjust for current conditions along with overnight 
temperatures and cloud cover.

Previous Discussion...
Thu should begin fair with much lgtr winds as sfc hi pres 
crests the FA from the W, with increasing hi cldnss from SSW to 
NNE late in the day in advc of the next low pres system from the
SE states.

Storm still on track for Friday with no significant change in
guidance over the last 12 hours. Still enough spread to greatly
impact the sensible weather in regards to total snowfall,
especially on the coast and across the far Northern Maine.
Essentially if the the further off the coast solution comes in
(GFS) camp, then the Downeast coast will get more snow then
forecasted. If the consensus forecast comes in, then still 
looks like a mix on the Downeast coast cutting down totals with 
higher amounts pushing further north into Maine. One thing that 
is certain is it looks like the first plowable snow for the 
Bangor region and the majority of Downeast with the Friday 
morning commute being impacted by snow. Low quickly pushes out 
Friday evening, with lingering snow across Northern Maine until 
midnight. Saturday will have weak cyclonic flow aloft over the 
area with some light snow shower activity for western areas and 
high temps getting into the upper 20s and 30s.

Forecast Confidence looks to be below average late this weekend
leading into Thanksgiving week. What we are confident about is 
that this period will have well below avg temperatures with a 
few shots of cold weather. In general the mean 500mb trough will
stay entrenched across the Northeast CONUS with multiple 500mb 
shortwaves moving through with weak waves developing on the 
surface cold fronts. In general western mountains will keep 
light snow shower activity at times through this period. Overall
didn't feel enough confidence on timing of pops, so broad 
brushed with some higher pops over the terrain and on Monday as
the potential for another weak storm still exists. Overall we 
should run 10 to 15 degrees below average for this period, with 
the chance for a slight warm up on Monday.

NEAR TERM: Local MVFR ceilings and patchy blowing snow are 
possible across northern areas early tonight. Otherwise, VFR 
conditions are expected across the region tonight through early
Thursday night. MVFR/IFR conditions will develop later Thursday
night. Northwest winds will gust to 30 to 35 mph early tonight,
then decrease overnight. 

SHORT TERM: Significant aviation impacts possible on Friday with
snow causing low vis and ceilings to impact all TAF Terminals.
Conditions will improve by Friday night with no significant
aviation impacts expected this weekend.

NEAR TERM: A Gale Warning remains in effect across the waters
until 1 AM, with a follow-up SCA likely needed late tngt into 
erly Thu morn. A pd of less than SCA winds/seas will follow for 
late Thu morn thru the aftn. Small craft advisory conditions
will then develop later Thursday night.

SHORT TERM: Possible GALE conditions on Friday as a coastal low
moves up the coast and crosses the Gulf of Maine during the day
on Friday. Seas will build to 10 feet over the outer coastal
waters on a E to NE wind.

ME...Winter Storm Watch from late Thursday night through late 
     Friday night for MEZ004>006-010-011-015>017-031-032.
