.SYNOPSIS...
Winds ease this morning as high pressure crosses northern New
England. A weak Alberta clipper system will track north of the
area tonight and Sunday, but only light snow or snow showers
are expected across the north. A cold airmass follows this
system to start the week. Another clipper is then possible by
Tuesday.


&&

.NEAR TERM /THROUGH TODAY/...
Seasonable air returns today as high pressure crosses through
New England. Highs warm into the 30s across the south, with 20s
across the north. Upslope snow showers dissipate in the morning
across the north, with mainly sunny skies downwind of the
mountains through midday. Clouds then begin to increase late in
the day ahead of the next approaching system.

&&

.SHORT TERM /TONIGHT THROUGH SUNDAY/...
An Alberta clipper tracks north of the Great Lakes and through
Quebec tonight and during the day on Sunday. This brings a warm
front through northern New England overnight. Temperatures will
mostly hold in the upper teens and 20s overnight, but likely
begin to rise along the coastline overnight as southwesterly
flow increases. The warm front may bring some light snow showers
to northern areas as it passes through overnight, but
conditions look dry elsewhere with mainly clouds expected.

Much of the day on Sunday is spent in the warm sector of the
clipper system. With partly sunny skies, temps warm into the
upper 30s to low 40s for most spots. Across the mountains and
foothills, mainly low to mid 30s are expected.

The cold front associated with the clipper then crosses during
the afternoon hours on Sunday. Some snow showers are likely
across the north and through the higher terrain with the front`s
passage in the late morning to early afternoon. These then most
likely dry up as they move southward. Temperatures then begin
to steadily fall in the late afternoon behind the front as a
much colder airmass begins to move back into northern New
England.

.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
Friday evening long-term update...No major changes were made in
the long-term with latest NBM. Global models are starting to
latch onto another weak wave that may bring some additional
light snow to parts of the area on Christmas Day, but there`s
quite a bit of discrepancy on timing and location of the wave
this far out.

Previous long-term discussion...

Sunday night will be fairly chilly behind the front as lows dip
into the lower single digits above zero north, to the mid to
upper teens south. It will likely stay fairly breezy through the
night so wind chills may bottom out close to 10 below zero
north, to the single digits above across the south. Monday
should mainly be dry as high pressure moves into the region with
below normal highs ranging from the lower teens north to the
upper 20s and lower 30s south. That being said, we may see the
usual snow showers stick around in the mountains given upslope
westerly flow.

A ridge axis crosses the region Monday night and then the next
progressive clipper/shortwave moves into the area on Tuesday.
This clipper should have a little more moisture to work with but
amounts will still be fairly light. Given the forecast
temperatures, most of this precipitation should be in the form
of snow but some rain or a mix or rain/snow will be possible
along the coast. The best chances for a few inches of snow will
be over the higher terrain but we could see enough widespread
light snow for most in the forecast area to see a White
Christmas. Highs will be a bit warmer on Tuesday, ranging from
the low to mid 20s north to the mid to upper 30s south. The bulk
of the precipitation should move out by Tuesday evening but
snow showers will likely continue into Wednesday over the
mountains in northwest upslope flow.

We should mainly dry out by Wedensday evening (Christmas Eve),
which should help Santa`s travel across New England overnight.
As of now, it appears the dry weather will continue for
Christmas Day with slightly warmer temperatures. The next
shortwave then approaches Christmas night into Friday which
brings our next widespread precipitation chances but details
remain unclear a week out. At an early glance it looks very
similar to the progressive clippers we will see earlier in the
week.

.AVIATION /06Z SATURDAY THROUGH WEDNESDAY/...
Short Term...Mainly VFR continues through Sunday morning, with
any lingering MVFR ceilings at HIE improving this morning.
Westerly wind gusts of 25- 30kt ease this morning. MVFR ceilings
are then possible Sunday afternoon across northern terminals.

Long Term...VFR conditions return on Monday, with another
system possibly bringing more restrictions Tuesday that may last
into the first part of Wednesday. Otherwise, upsloping could
bring MVFR ceilings and snow showers at HIE the rest of the day
Wednesday.

&&

.MARINE...
Short Term...Westerly gales ease this morning as high pressure
crosses the waters. Southwesterly gales likely then develop
tonight ahead of an approaching cold front. The front crosses
the waters late Sunday afternoon, with SCA conditions or
marginal northwesterly gales possible behind the front by Sunday
evening.

Long Term...Northwesterly gales are then possible behind the
front Sunday night into Monday, and this will be followed by
another period of at least SCA conditions Tuesday into Tuesday
night as another clipper crosses the waters. Conditions then
improve Wednesday through Wednesday night as high pressure
builds across the region. High pressure shifts east late in the
week as another front approaches.
