Synopsis
Weak low pressure will cross the gulf of maine today and move
into the maritimes tonight. Another low will cross the gulf of
maine Tuesday.

Near term through tonight
7am update... Further reduced snow amounts towards the coast.

Have patchy freezing drizzle in the forecast and this remains
the biggest concern this morning as the moist maritime air moves
over the very cold surfaces inland. Still concerned about
freezing fog this evening in the penobscot river valley, but
will hold off including in the forecast as there's uncertainty
regarding clearing.

Previous discussion...

the departing arctic high leaves behind very cold air under a
steep inversion that set record lows at caribou, houlton and
millinocket this morning. This was the earliest zero reading
ever recorded at caribou.

Otherwise... A flat wave moving out of southern new england
early this morning will generate warm air advection overrunning
the cold in situ air mass. A baroclinic zone setting up in the
gulf of maine will yield weak surface low pressure that will
track just offshore today. Weak lift results in a period of snow
today that could amount to about an inch in a stripe from
bucksport towards calais... And maybe a half inch for bangor.

Little or no snow is expected further north. There's just
enough warm advection to bring temperatures above freezing in
coastal hancock and washington by later this morning and ensure
a changeover to rain. These coastal zones will also be where the
greatest QPF is forecast... Up to a quarter inch... But much of
it will be in the form of rain. There is some concern about a
warm nose around h950 into southern penobscot and interior
hancock washington for this afternoon. Since cold air at the
surface will be locked in north of the coastal zones... This warm
nose and dense moisture up to h700 could squeeze out some
freezing drizzle. Not expecting any accumulations... And with
temperatures close to freezing after previous snowfall... Impacts
should be minimal. Further north, a new arctic front will reach
northern aroostook later in the afternoon with some snow
showers. This front will tend to stall out and lose its identity
overnight as weak high pressure noses into the area. Have some
concerns about freezing fog developing in the southern half of
the forecast area tonight with any clearing. The baroclinic zone
remains in the gulf of maine overnight and a much more potent
upper level shortwave in the northern stream will phase with
it... Leading to cyclogenesis in southern new england by the end
of tonight.

Short term Tuesday through Wednesday night
Intensifying low pressure will track across the gulf of maine
Tuesday, then exit across the maritimes Tuesday night. However,
the exact track of the low is still uncertain. The low will
bring accumulating snow to downeast and central portions of the
forecast area Tuesday, with lesser snow chances across northern
areas. Snow totals Tuesday will be dependent on the eventual
track of the low. Preliminary snow estimates Tuesday are 3 to 5
inches downeast, 1 to 3 inches across central portions of the
forecast area, with around an inch or less across northern
areas. These values could increase or decrease dependent on the
eventual track of the low. Snow will taper to snow showers in
the wake of the low Tuesday night. Another low will begin to
cross the region Wednesday, drawing a strong cold front across
the region later Wednesday through early Wednesday night. Snow
showers will occur across the region Wednesday, with snow
squalls also possible in the vicinity of the cold front. Very
cold air will be drawn across the region in the wake of the cold
front Wednesday night with increasing northwest winds. Snow
showers will diminish across central and downeast areas later
Wednesday night, while persisting across the north and
mountains. Temperatures will remain at below normal levels
Tuesday Wednesday, with very cold temperatures advecting across
the region Wednesday night. Wind chill readings will reach 15 to
20 below zero across northern areas later Wednesday night, with
around 10 below to 15 below zero downeast.

Long term Thursday through Sunday
Record cold temperatures are expected across the region
thanksgiving along with strong gusty northwest winds. Wind
chills should remain at sub-zero levels across the north and
mountains, only reaching around zero downeast. Otherwise, expect
mostly cloudy skies along with a chance of snow showers across
the north and mountains, with partly cloudy skies downeast
during thanksgiving. Cold high pressure will begin to build
across the region Friday with decreasing winds along with partly
cloudy skies north, mostly clear downeast. High pressure will
cross the region Saturday with partly cloudy mostly sunny skies.

High pressure will exit across the maritimes Sunday, while low
pressure intensifies southwest of the region. Cloud cover will
increase Saturday night. A wintry mix is then expected to expand
across the region later Sunday, though precipitation amounts
and types remain uncertain. Record cold is expected
Thursday Friday. Temperatures will begin to moderate
Saturday Sunday though remain at below normal levels.

Aviation 12z Monday through Friday
Near term:VFR conditions at all sites will deteriorate to MVFR
towards bgr and bhb this morning... And eventually to ifr in
snow... Then due to CIGS and drizzle. Further north, expect MVFR
cigs to develop by this afternoon. A weakening cold front may
briefly drop sites north of pqi to ifr vis in snow showers this
evening. Sites north of hul will probably stay MVFR through the
night. Further south, ifr CIGS will eventually lift to MVFR
later tonight.

Short term: MVFR conditions are possible across northern areas
Tuesday through early Tuesday night, with ifr lifr conditions
downeast. Occasional MVFR conditions will remain possible across
the north and mountains later Tuesday night withVFR conditions
developing downeast. Variable conditions will occur across the
region Wednesday with snow showers and possible snow squalls.

MVFR, with local ifr, conditions are expected across the north
and mountains Wednesday night withVFR conditions developing
downeast. Occasional MVFR conditions will remain possible across
the north and mountains during thanksgiving, with generallyVFR
conditions downeast.VFR conditions are expected across the
entire region Friday. Northwest winds will increase in the wake
of a strong cold front Wednesday night. Strong gusty northwest
winds are expected across the entire region during thanksgiving.

Marine
Near term: rain and snow are expected today... Along with areas
of drizzle that will reduce visibility. Winds will be light and
seas are expected to remain at 2 feet or less.

Short term: small craft advisory conditions are expected
Tuesday through Wednesday. Gale conditions will then develop in
the wake of a strong cold front Wednesday night. Visibilities
will be reduced in rain snow Tuesday into Tuesday night, with a
chance of snow showers Wednesday afternoon into Wednesday night.
