.SYNOPSIS...
A dry cold front will drop out of Canada will move through
early this morning bringing northerly breezes and temperatures
ten to as much as 20 degrees cooler than yesterday. Cooler
temperatures will persist through Friday before warming again
over the weekend. Areas of frost mainly outside the Champlain
Valley are possible, especially Wednesday and Thursday nights.
The next chances of rain will likely hold off until early next
week.

.NEAR TERM /THROUGH WEDNESDAY/...
As of 223 AM EDT Tuesday...Water and IR imagery are highlighting
a sharp frontal boundary tracking south out of Canada at this
hour. Thermal packing is tight across the boundary which will
result in strong cold air advection. However, the boundary and
airmass pushing it are quite dry. As a result RH will be
dropping through the day with minimums generally ranging 30-40%.
With gusts around 20 mph some very isolated fire weather
concerns are possible for localized areas like exposed north-
facing mid/upper slopes and portions of the Champlain Valley.
With ongoing drought, a little extra care to not create sparks
would be advisable. Temperatures drop sharply overnight with
continued cold air advection. While lows will range 30-40
degrees for many locations outside the Champlain Valley, the
pressure gradient should be tight enough to keep winds going for
most spots except for a few sheltered hollows. Breezes continue
WEdnesday, and could slightly increase; lake wind gusts up to
20-30 mph will lead to rough conditions on Lake Champlain
Wednesday. For fire concerns, RH will not be critical since
high temperatures will be markedly lower ranging in the 50s to
around 60 degrees for most locations.
&&
.SHORT TERM /WEDNESDAY NIGHT THROUGH THURSDAY/...
As of 223 AM EDT Tuesday...The pressure gradient is expected to
weaken sharply as high pressure moves more overhead Wednesday
night into Thursday. Clear skies will promote a strong radiation
inversion and colder overnight lows mainly in the 30s to around
40 degrees. Most locations outside of the immediately Champlain
Valley could see some frost as a result. Temperatures will
marginally warm over Wendesday`s highs as the air mass begins to
modify; highs in the mid/upper 50s to mid 60s are favored
Thursday afternoon.
&&
.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
As of 223 AM EDT Tuesday...More frost is possible Thursday
night, but winds will likely begin shifting southerly overnight
as large high pressure continues to be favored to be
progressive and drop southward. The long wave over southern
Canada and northeastern US will become increasingly zonal over
the weekend supporting some opening of flow to fast moving
systems. Meanwhile, return flow around the high`s periphery at
lower levels supports warming temperatures. Bended guidance
points to highs warming back above seasonal averages into the
70s for Saturday and nearing 80 for a few locations by Sunday
afternoon. High pressure will eventually roll off shore early
next week clearing the path for some showers. While blended
guidance points to Tuesday for showers, model biases and some
global models suggest showers could possibly hold off until mid
week.
&&
.AVIATION /11Z TUESDAY THROUGH SATURDAY/...
Through 12Z Wednesday...VFR conditions are strongly favored for
most locations through the forecast period. Otherwise,
northerly flow will be increasing with speeds becoming 10-15kts
with some gusts up 25kts for channeled valleys; BTV/PBG were
capped at 20kts, but there could be a few gusts to 25kts in the
18-21Z time frame. Winds decrease after 23Z, but will likely
keep some northerly component through the remainder of the
period. There could be some fog encroaching on SLK/MPV/EFK tonight
after 06Z, but winds remains aloft and could preclude fog
formation.
Outlook...
Wednesday: VFR. NO SIG WX.
Wednesday Night: VFR. Patchy frost.
Thursday: VFR. NO SIG WX.
Thursday Night: VFR. NO SIG WX.
Friday: VFR. NO SIG WX.
Friday Night: VFR. NO SIG WX.
Saturday: VFR. NO SIG WX.
