Synopsis
Low pressure will track up the east coast and bring snow and
rain to new hampshire and maine on Tuesday. While many areas may
start as snow, expect much of the coastal plain and southern new
hampshire to change to rain while more significant snow
accumulations are limited to northern areas. As the low moves
off to the northeast it will pull in some much colder air on a
strong northwesterly wind Tuesday night and Wednesday. This cold
air will stick around through Thursday with the next nor'easter
arriving on Friday.

Near term until 6 am Tuesday morning
630 pm update... Only change to the forecast early this evening
was to drop temperatures faster for the next 1-3 hours due to
radiational cooling. Otherwise, everything else looks to be on
track.

Previously...

high pressure slides off to the east tonight with increasing
clouds arriving from the southwest. Expect temperatures to fall
most quickly in the evening tonight before cloud cover limits
further cooling. Coolest temperatures will be in the east where
cloud cover will have the least effect, while southwestern parts
of the area may see rising temperatures by morning as
precipitation arrives in advance of the next low pressure
system. Expect much of the area to see the first bit of the
precipitation fall as snow, with temperatures warming as it
arrives, changing it to rain over southern areas before much
accumulation.

Short term 6 am Tuesday morning through Tuesday night
Low pressure tracks across CAPE cod on Tuesday and strengthens
as it pulls toward nova scotia. It will be wrapping in a fair
amount of warm air, so the rain snow line will push a good ways
inland, likely all the way to the foothills mountains. Snow
accumulation in northern areas will likely reach the 6 to 8 inch
range, so a winter storm warning has been issued there in
collaboration with our neighboring offices. We have also
expanded the winter weather advisory a bit southward.

Accumulations in the transition area are highly uncertain, but
with the amounts currently expected and the transition to rain
likely making snow covered surfaces even more slippery during
the morning commute, opted to expand the advisory. Precipitation
should come to an end Tuesday afternoon or early evening as the
low quickly pulls away.

As it does pull away we will get a strong northwest flow
developing behind it, ushering in some much colder air. Timing
of this moving through during the overnight hours makes it a bit
less certain as to how much of the low level wind flow will be
able to mix to ground level. However, considering the strong
cold advection which will shift the low level environment from
inverted to well mixed in a hurry, expect that we will see a
good deal of gustiness once that colder air arrives during the
night Tuesday night. We may eventually need a wind advisory for
this period, but for now am forecasting wind gusts just below
criteria.

Long term Wednesday through Monday
The deep upper trof will be passing and exiting to our north as
it moves east into the maritimes wed. A very strong cyclonic
linear low-mid level jet with the northwest flow will cause
very strong gusty winds and will likely require some headlines
but its still 4th- 5th periods so will hold off for now. Very
strong CAA Wed with falling temps through the day, certainly no
diurnal curve. H85 temps to fall to -15c to -20c by Wed afternoon.

Wed night the strong gusty winds will continue into the evening
followed by some abating of the winds by later in the evening
as the cold dense air mass settles in. Wed night will be the
coldest night so far this season as temps fall into the single
numbers in the mountains and teens elsewhere. Weak high pressure
briefly settles over the area although WAA high clouds will be
spilling over the upper ridge from the approaching southern
system.

Thu night the deep arctic air mass will be in place. Models
agree in lifting the sfc upper low out of the gulf of mexico and
then up the east coast Thu night and then along or off the new
england coast fri. The euro is furthest north and wettest with
1+ inches of QPF while the other models are further south with
about half the qpf. Considering source region of gulf system,
high pwat's expected, combined with more latent and sensible
heat release off the warm ocean waters as it moves up the east
coast. Of note all models are trending further south each run.

Based pops Fri on euro solution and a sfc mid level track along
or just off the maine coast. Significant snowfall likely in the
mountains and foothills as this should be primarily a snow
event. Inland areas further south may also see some
accumulations. Using h85 -2c to -5c and using an area 1.5-2 degs
west of the low-mid level track puts a swath of heaviest
amounts into the mtns foothills fri. With the depth of the
arctic air mass in place, stg cold air damming expected and
forecast highs Fri likely too warm and may need to be adjusted
even colder.

The system quickly exits northeast into the maritimes by later
fri night with clearing in its wake with weak high pressure
moving in for sat. Some lingering snow showers expected in the
mountains.

A clipper will approach later Sat into Sun possibly spreading
snow showers into the mountains Sat night and Sun and then
elsewhere by Sun evening.

Aviation 00z Tuesday through Saturday
Short term... Expect increasing clouds and lowering ceilings
through the night, with precipitation arriving by morning. Will
likely see precipitation start initially as snow at most spots
before quickly transitioning to rain for southern and coastal
areas with ifr conditions lasting most of the day. As
precipitation and lower ceilings move out Tuesday afternoon, a
much colder air mass will be ushered in on strong northwest
winds during the night.

Long term... Strong gusty NW winds to 40+ kts possible Wed with
winds subsiding Wed night.VFR conditions wed-thu. Conds lowering
to ifr lifr late Thu night over southern areas and all areas fri.

Conds slowly improve toVFR later Fri night. Lingering MVFR
conditions expected in the mountains into sat.

Marine
Short term... Low pressure will be strengthening as it arrives
and passes through the gulf of maine on Tuesday. Thus expect
gale force gusts over the outer waters in the south to southeast
flow ahead of the low on Tuesday, while the entire gulf of maine
gets in on the northwesterly gales beginning Tuesday night after
midnight.

Long term... Strong gale force winds expected Wed into Wed evening
before slowly diminishing thu. The next coastal low is expected
to track near CAPE cod on Friday into Fri night with stronger
winds possible ahead of and behind this storm as the center tracks
across the coastal waters of the gulf of maine.

Hydrology
Rainfall amounts tonight through Tuesday are not expected to
cause any river flooding at this time. However, ponding of water
on roads and other low lying areas is expected.
