Synopsis
Low pressure will exit eastward into the gulf of maine this morning,
allowing for gusty north winds and lingering, abundant low
cloudiness. The overcast will limit high temperatures to the low to
mid 60s in most locations. Also, a few showers or sprinkles will
remain possible, mainly across the northern mountains. Clearing
skies will develop this evening, along with diminishing winds as
high pressure builds in from the eastern great lakes region. The
tranquil weather will only last through the first half of Saturday.

Thereafter, a warm front pushing in from southwest new york will
allow widespread showers to develop across the region from west to
east late in the afternoon or evening, into Saturday night. Briefly
drier conditions are expected Sunday morning, followed by the
redevelopment of scattered showers and possibly a few thunderstorms
during Sunday afternoon.

Near term through Saturday
As of 217 am edt Friday... Surface low pressure (1000mb) and
attendant vigorous mid-level vort centered near sherbrooke, que.

At 06z will translate esewd across maine and offshore through
the remainder of this morning. This will set up a moderate n-nw
low-level gradient flow across the north country, with winds
10-20 mph with gusts to 25 mph for a time late this morning into
the early afternoon hours. May even see a few gusts closer to
30 mph in the ct river valley around midday. With low-level caa,
900-850mb layer will help to trap some low cloudiness, which
should linger much of the day per 00z NAM model soundings.

Breaks in the overcast will first appear east of the adirondacks
and greens in downslope areas, followed by a gradual clearing
later in the afternoon or toward evening for the remainder of
the north country. Some light rain showers are also possible
early this morning, gradually becoming confined to far NRN nern
vt with orographic effects allowing for some continued sprinkles
through 16z or so. Have shown pre-dawn pops 30-50 percent near
the international border, but trending below 15 percent by noon
or so. The stratus and north winds will result in daytime highs
holding in the low-mid 60s in most locations.

Skies should clear quite rapidly this evening setting up quiet
conditions tonight as high pressure moves in from the ERN great
lakes. With winds becoming light and variable, temperatures will
fall into the mid-upper 40s for overnight lows, except closer
to 40f for lows at kslk and across vermont's northeast kingdom.

Sheltered locations may reach crossover temps, and added in some
patchy fog for the climo favored spots tonight. Pops nil.

Saturday begins dry, but surging 850-700mb warm frontal zone brings
increasing afternoon cloud cover and developing rain showers.

Showers should develop first across NRN ny (17-20z) and then across
vt (20-23z), with pops reaching 60-80% by 22z from the champlain
valley wwd. Also, appears some weak elevated instability makes it
into NRN ny on wswly 50-55kt 850mb jet. Thus, added a slight chance
of a thunderstorm across franklin ny and st. Lawrence counties late
in the afternoon where a few embedded convective elements are
possible. Rainfall through 00z Sunday should range from <0.10" east
of the green mtns, to 0.10-0.20" across the champlain valley and
adirondacks, and slightly higher across st. Lawrence county where
rainfall arrives soonest. Highs Saturday mainly lower 70s across
vermont, but upper 60s to lower 70s across ny with earlier arrival
of clouds precipitation.

Short term Saturday night through Sunday
As of 301 am edt Friday... A line of showers will move through
the area from west to east early Saturday night, driven by
subtle height falls aloft and a low-level moisture boundary
moving through. The heaviest rainfall will be in the early
overnight hours, when pwats will briefly surge to 1.4 to 1.6"
ahead of the boundary. There will be some elevated instability
during the early overnight hours, so have included a slight
chance of thunder for much of northern ny and into southern vt
through around midnight. Shortly after midnight, rain showers
will diminish with the loss of instability and moisture, and the
area should be mainly dry by sunrise. Overnight lows will range
from the low 50s in eastern vermont to the mid and upper 50s
from the champlain valley west.

Sunday morning will start off cloudy but dry. By late morning,
some breaks in the clouds will develop, allowing for increasing
instability to build as the area remains within the warm sector
of a canadian low pressure system. Temperatures will rise into
the mid to upper 70s by early to mid Sunday afternoon before a
frontal boundary moves through. Some convective showers will
develop during the afternoon as the front moves through. Cape
values progged to rise to over 500 j kg ahead of the boundary
supports the potential for some embedded thunderstorms to
develop within the convective showers, although this will depend
on how much the atmosphere can really destabilize after the
Saturday night early Sunday morning system moves through.

Long term Sunday night through Thursday
As of 301 am edt Friday... Long term forecast will be driven by
strong high pressure centered over the gulf of
mexico southeastern us and troughing further west over the
rockies and into the central plains. This pattern puts the btv
forecast area within an active storm track as multiple systems
lift out of the plains and travel up and over the ridge top into
new england. These systems are by nature fast moving and
notoriously difficult to time this far out. Currently, it
appears Monday will be dry as a brief ridge of high pressure
builds in, but precipitation chances return Tuesday through
Thursday as a series of low pressure systems and associated
fronts lift through the area. Temperatures during the mid-week
time frame could get quite warm as the pattern will support
strong warm air moisture advection into the area. A few days
approaching exceeding 80 degrees in valley locations doesn't
look out of the question for the middle of next week.

Aviation 07z Friday through Tuesday
Through 12z Saturday... Surface low pressure near sherbrooke,
quebec will be exiting into the gulf of maine later this
morning. As this occurs, will see winds shift from west to
n-nw across the north country TAF sites, generally 10-15kt with
a few gusts approaching 20kt during the mid-morning through
early afternoon hours when gradient flow will be strongest. The
low-level northerly flow will be relatively moist, and most taf
locations will see MVFR ceilings throughout the morning hours
with hir trrn obscd. A few showers are also possible through 14z,
mainly in the northern mountains. Ceilings will gradually
improve back toVFR with binovc this afternoon, followed by more
significant clearing skies toward just after sunset and through
the overnight period. Likewise, winds will become light and
variable after 00z Saturday with high pressure building into
ny new england from the great lakes region tonight.

Outlook...

Saturday:VFR. Chance shra.

Saturday night: mainly MVFR, with local ifr possible. Definite
shra.

Sunday: mainlyVFR, with local ifr possible. Chance shra, chance
