.SYNOPSIS...
A weak area of low pressure will bring periods of mainly snow to
the interior today with a mixture of rain and snow showers over
southern and coastal locations. Several inches of accumulation
are expected over the foothills and points north. Dry conditions
along with moderating temperatures is then expected for the
middle of the week before another area of low pressure brings
renewed chances for unsettled weather towards the weekend.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Latest RAP13 surface pressure analysis early this Tuesday
morning shows low pressure located over upstate NY with the h5
low trailing behind to the west over southern Quebec. Northeast
radar mosaic shows precipitation streaming eastward over eastern
NY and approaching western VT with a secondary area of
precipitation streaming northeastward over the southern Gulf of
Maine in association with a stationary front. Across the local
area there is some low clouds/fog being reported across portions
of southern NH and webcams/ASOS indicate some light
snow/flurries at times falling out of the low-level cloud deck.
Latest hi-res guidance continues to indicate that more
widespread precipitation will overspread NH between roughly
6am-8am before spreading into western ME later this morning.
Cold temperatures aloft will allow for the vast majority of this
to fall as snow and a coating to a slushy inch is possible over
mainly NH through around 8am.

Later today the aforementioned sfc low will cross near the
Canadian Border while gaining added support by a strong upper
level low for this time of the year. This will provide growing
upper level divergence with a vort max and growing frontogenetic
forcing allowing for increasing precipitation rates during the
afternoon and evening across western ME. This can be seen
through the latest WPC snowband probability tracker, which
shows the potential for snowfall rates of 1"/hr possible for
several hours beginning late afternoon through mid-evening with
the highest probability for these increased rates from roughly
along a line from Bethel to Lewiston/Auburn and points east.
Over NH, increasing westerly flow will assist in bringing a dry
slot eastward, which will end most of the snow and rain by the
mid- day, although it will linger through the day across
northern NH and the mountains.

Total snowfall through today is forecast to range from a coating
or less along the immediate coast and southern NH to 1-3" inland
from the coast to the foothills. From the foothills and points
north 2-4" can be expected with locally higher amounts across
the mountains. High temperatures will range from the middle 30s
to lower 40s from north to south.

Another concern for late this afternoon and evening is
developing gusty westerly winds in the wake of this strong
late season upper level low. Latest soundings indicate around
45-50 kts at the top of the mixed layer and the last several
runs of the HRRR indicate a growing potential for widespread
surface wind gusts up to 35 mph with a relatively short window
of gusts nearing 50 mph across portions of the ME foothills and
extending into south-central NH. The latest MAV guidance also
shows this potential for impactful gusts and therefore went
ahead and issued a wind advisory for portions of the area, which
will run from 4pm this afternoon through midnight tonight.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM WEDNESDAY/...
Snow will exit western ME through the first half of tonight as
low pressure exits over the Maritimes. An additional 1-2" of
accumulation will be possible in spots. It will otherwise be a
blustery cold night with low temperatures falling into the teens
and 20s. Gusty westerly winds will gradually weaken after
midnight but will remain elevated enough to send windchills into
the single digits and teens.

High pressure will begin to build to our south on Wednesday as a
much drier airmass settles into the region. Temperatures aloft
will remain quite cool though with h85 hovering around -10C.
This will limit highs to the 30s and 40s.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/...
No significant changes to the going long term forecast. The main
weather event of the long term period still looks to be the
chance for some occasionally heavy rain over the weekend that
could start as a mix in spots Friday.

Previously...
Wed night should be mainly clear with calm winds, and some rad
cooling can be expected. Lows range from 15-20 in the mtns to
the low to mid 20s in the S, probably making it the coldest
night in the forecast range. Thursday looks mostly OK, as winds
shift SSW, although there will be increasing clouds in the
afternoon. Highs range from the low to mid 40s N to the low 50s
S. Thu night looks mostly dry too, but wind will begin to shift
onshore, and clouds will overspread the area, as well, so mins
will mostly be in the 30s. Despite my chance POPS, Im leaning
toward limited showers on Friday, but, with onshore flow through
most of the day it will be cloudy, and highs will generally be
in the 40s, as the marine lyr settles in.

As mentioned, models have shown some run-to-run consistency for
precip Fri night into Saturday, and this where there are some
likely POPS. Its warm enough, that only it will be rain. The
only exception at times, may be the highest elevations. Even
this, just based on the pattern seems low confidence, and by the
time we get to Sunday confidence is even lower.

&&

.AVIATION /07Z TUESDAY THROUGH SATURDAY/...
Short Term...-SNRA will overspread the region this morning from
west to east, arriving at most NH TAF sites by 13Z before
approaching KAUG/KRKD by 15Z. Periods of mostly SN and IFR/LIFR
restrictions can be expected through much of the day across ME
sites along with KHIE but improvements are expected at KLEB,
KMHT, KCON, and KPSM by this afternoon. SN could fall heavily at
times late this afternoon and evening at KAUG and KRKD. Westerly
winds will increase after 20Z with a period of 40 kt gusts
expected at KMHT, KPSM, and KCON with 30-40 kts elsewhere
through 04Z Wednesday. Ceilings and lingering SN over ME will
lift and end later tonight with westerly winds of 15-25 kts. VFR
conditions then prevail Wednesday with northwesterly winds up
to 25 kts. No LLWS is anticipated through the period.

Long Term...VFR is expected Wed night thru Thu at least.
Probably sometime Thu night as the flow shifts onshore, will
begin to see IFR or lower first at the coastal sites, and later
further inland, sometime on Friday. KLEB/KHIE, may not see any
restrictions through Friday as they will be downsloping in the
onshore flow. Friday night and Sat expect restrictions
everywhere in rain and low cigs.

&&

.MARINE...
Short Term...A strong cold front and upper level low will cross
today into tonight with increasing westerly gales developing
late today and persisting through early tonight outside of the
bays with SCAs across the bays. Seas of 4-7 ft are likely over
the outer waters with 1-3ft in the bays. Winds and seas
gradually diminish late tonight through Wednesday but SCA
conditions may linger through mid-day Wednesday.

Long Term...Winds and seas largely to remain below SCA
thresholds through Saturday.
