.WHAT HAS CHANGED...
Tonight should feature a fairly steady breeze at least through
midnight. After, a few locations across the interior and
foothills may rapidly cool should clear skies prevail.
Continued to mention isolated snow showers in the forecast for
late Saturday.
&&
.KEY MESSAGES...
1. Temperatures fall well below normal tonight through Saturday
night as cool, continental air arrives from Canada.
2. Wintry weather remains possible late next week, as the weather
pattern is expected to stay active.

.DISCUSSION...
KEY MESSAGE 1 DESCRIPTION...
The trend to full sun today has been deceptively cool given the
breezy conditions and stagnant to falling temperatures. Temps
will continue to cool into the teens and lower 20s for much of
the area overnight. Even cooler temps in the single digits are
likely across the northern valleys.
Cold air advection amid a much cooler airmass will be the
primary driver, but may see a narrow window of radiational
cooling tonight. Low level winds should maintain some level of
mixing through the evening and early overnight hours, with
another round of clouds arriving right as they slacken. This
could leave pockets of good cooling conditions with values
outside of the mountains falling into the lower teens or upper
single digits.
Breeze ticks up again Saturday as a wave approaches from the
west. Could see some isolated snow showers as this moves through
later in the afternoon/evening, but mtns to the west and
weakening daytime heating (amid an otherwise cool day in the
upper 20s and 30s) could make these sparse.
Saturday night stands the chance for running a few degrees
below current forecast depending on the sky forecast. If clouds
abate, radiational cooling seems more likely as winds will be
lighter as high passes just to the south. With a couple rounds
of low level moisture riding around the top of the ridge, it
will again be a tricky overnight temp forecast.
KEY MESSAGE 2 DESCRIPTION...
Warm front is forecast to lift into the forecast area Mon
night. I expect that low clouds will begin to develop prior to
showers moving in from the west. The set up looks fairly
favorable for prolonged period of dreary weather. At this time
range the details are tough to pin down, but showers, fog,
drizzle are all possible. This first event looks to be on the
warmer side with low pressure tracking thru southern Canada. I
could see temps coming in colder than NBM guidance with high
pressure lurking just north of the border. Ensembles show very
little threat of wintry precip over the southern half of the
forecast area, but northern zones are likely to see at least
some light accumulation before any changeover occurs. A cold
front crosses the region around Wed but a follow up wave will be
right on its heels to end the work week. This second wave has a
much better potential to be wintry. A strong high pressure is
currently forecast to migrate across Quebec and will be in a
good position set up a cold air dam. Ensemble guidance even has
a snow threat as far south as southern NH. This is really the
one to watch.

.AVIATION /18Z FRIDAY THROUGH WEDNESDAY/...
Through 18z Saturday...VFR under SKC this afternoon and evening
with gusts to 20 kt. Winds slacken overnight, but a NW breeze
should continue. Will see some MVFR ceilings make their way into
the mountains this evening for HIE. Winds tick up again Saturday
morning, but not as gusty as today.
Outlook:
Saturday night: May see a brief line of SHSN move across NH and
southern ME terminals late Saturday. Otherwise, VFR prevails.
Sunday and Sunday night: VFR. Some MVFR cigs are possible
towards the US/CAN border.
Monday: VFR, no sig wx.
Monday Night: IFR conditions possible with low CIGs developing
as warm front moves into the area.
Tuesday: Areas of IFR possible.
Tuesday Night: Areas of IFR possible.
Wednesday: Cold front forecast to cross the region and
conditions will improve to VFR behind the front.
&&
.MARINE...
SCA conditions continue this evening and overnight in the wake
of exiting cold front. Wave heights will slowly fall below
criteria Saturday. Below SCA conditions are forecast through
Saturday night as high pressure passes south of the waters.
A prolonged period of southerly to southwesterly winds are
forecast to develop early to midweek. The sustained direction
should allow seas to build above 5 feet outside of the bays
rather quickly, with gusty winds continuing thru the end of the
week.
