.WHAT HAS CHANGED...
Snowfall amounts have continued a downward trend as the heaviest snowfall
remains offshore with low pressure now pulling away from the
Gulf of Maine. Therefore, have canceled the Winter Weather Advisory
in Cheshire County where snow is coming to an end and across interior
zones in Maine where snowfall amounts will fall short of Advisory
criteria in the 1-3 inch range. Winter Weather Advisories remain
in tack elsewhere where accumulations will be around 4 inches.
&&
.KEY MESSAGES...
1. Light snowfall through day break will bring slick travel this
morning. Snowfall will taper off from NW to SE while an inverted
trough may continue accumulating snow across southeast New Hampshire
and coastal Maine through late morning.
2. A clipper system may bring a period of light snowfall Wednesday
night before an Arctic airmass arrives for the remainder of the week
through the upcoming weekend.

.DISCUSSION...
KEY MESSAGE 1 DESCRIPTION...
Low pressure is roughly 200 miles ESE of Cape Cod as of this
writing and is now pulling away towards Nova Scotia. Latest
available NWP guidance has continued a downward trend in QPF and
resultant snowfall as the heaviest snowfall has remained
offshore. The back edge of the light snowfall is now moving
across the CT Valley and light snowfall will continue to taper
off from NW to SE during the pre dawn hours.
As low pressure offshore continues to pull away the final short
wave is this busy upper air pattern slides across the eastern
Great Lakes. Mesoscale and global models continue to suggest
this short wave will result in an inverted trough extending
northwestward from the low that will continue chances for snow
across southeast NH and coastal Maine through late morning.
Latest storm total snowfall calls for 1-2 inches along and south
of the mountains and 1-3 inches across interior Maine and
south-central NH. Where Advisories remain in tack snowfall
amounts will range from 3-5 inches with slick travel here likely
through the morning. Chances for snow will come to an end by
this afternoon with the exception being snow snow showers in the
mountains.
KEY MESSAGE 2 DESCRIPTION...
Geopotential heights will gradually rise Tuesday night into
Wednesday with H8 temperatures warming to around -15C by Wednesday
afternoon. Mainly clear skies and light winds combined with the
snowpack will allow low temperatures Tuesday night to fall into the
single digits either side of zero. Wednesday will feature increasing
clouds with highs into the teens across the north with 20s in most
other locations. A clipper system may bring a period of light snow
or snow showers Wednesday night, which may result in some slippery
travel conditions persisting into the Thursday morning commute.
Flow will briefly become SSW on Thursday, allowing for a warmer
day with high temperatures into the 30s to near 40 degrees south of
the mountains. Arctic air will then move into the region Friday
through the upcoming weekend with well below average temperatures
and a high likelihood for cold weather advisories/warnings.
High temperatures on Saturday and Sunday may only be single
digits for many areas with lows well below zero. Windchill
values may approach 30 below in some locations.

.AVIATION /06Z MONDAY THROUGH FRIDAY/...
Through 06Z Tuesday.. MVFR/IFR expected rest of tonight as SN
continues with vis impacts greatest for southern NH terminals
and coastal ME terminals. Light snow continues for the forecast
area into this morning where snow will lift across the area
with additional period of lower vis. This begins to exit
northeast after 18z, with VFR trend into this evening.
Outlook
Monday Night: Ocnl SN remains for HIE into the overnight
hours, otherwise VFR with gusty WSW winds 15 to 20 kts.
Tuesday: VFR prevails at all terminals. Westerly wind gusts
20-25 kts possible in the afternoon.

than 20 kts.
Wednesday night: Some restrictions possible due to -SN. Forecast
confidence is low.
Thursday: VFR conditions with SSW winds prevailing.
Friday: VFR conditions with W wind gusts up to 25 kts possible.
&&
.MARINE...
Winds and seas will be on a brief downward trend into day break
as low pressure pulls away from the Gulf of Maine. An inverted
trough extending from the low may continue snow over the waters
through mid day. Winds then increase Monday afternoon as a cold
front approaches from the west. The passing front will bring
potential for westerly Gales Monday night through Tuesday.
SCA to near gale force winds will persist Tuesday night
through the upcoming weekend along with elevated seas. Freezing
spray is also likely as very cold air moves across the waters.
