Area Forecast Discussion
National Weather Service Burlington VT
310 AM EDT Mon Sep 14 2020

.SYNOPSIS...
A cold front will continue to push through the North Country this 
morning with clearing skies expected to rapidly develop behind the 
front. Winds will switch from the southwest to northwest late 
morning into early this afternoon and we will see gusts of 15-20 mph 
this afternoon before weakening this evening. Widespread frost is 
expected for much of the region with the exception of the Champlain 
Valley with several locations across the northern Adirondacks and 
northeastern Vermont dropping into the mid 20s to lower 30s. A 
warming trend will be seen Tuesday and Wednesday with afternoon 
highs warming into the lower to mid 70s by Wednesday. Another front 
will push through the region on Thursday and Friday and bring 
another bout of below normal temperatures to the region for next 
weekend.

&&

.NEAR TERM /THROUGH TUESDAY/...
As of 310 AM EDT Monday...Decreasing clouds will be seen through the
morning hours across the North Country as colder air filters out of
Canada and spreads across the region. Latest satellite imagery shows
the back edge of the cold front located across central St. Lawrence
County and will continue to push eastward throughout the morning and
early afternoon hours. Clear skies are already being reported at
Massena which credence to the dry air depicted by global and local
models. This dry air should quickly displace any residual moisture
with partly to mostly sunny skies expected across the region by mid-
afternoon. Noticeably cooler temperatures are on tap today as strong
cold air advection will be combating the increasing sunlight this
afternoon. Highs this afternoon are only expected to climb into the
upper 50s to mid 60s with the mountaintops across the Green and
Adirondack Mountains staying in the 40s to possibly lower 50s. Given
the amount of dry air at the surface and cold air advection in the
mid-levels, we will likely see 15-20 mph gusts develop late this
morning across much of the region with winds rapidly diminishing
around sunset and the surface and boundary layer decouple.

The coldest night since mid May/early June is expected tonight as
temperatures will drop into the upper 20s to lower 40s. Freeze
warnings have been issued for western Essex and southern Franklin
Counties in New York and Essex County in Vermont. Frost advisories
have also been issued across much of the North Country with the
exception of the Champlain Valley and southern Vermont. Temperatures
will plummet following sunset as cold high pressure crests overhead
leading to clear skies and calm winds. Those with sensitive
vegetation may want to take precautionary actions given the early
season frost/freeze expected tonight. Temperatures will warm quickly
on Tuesday as plentiful sun allows our afternoon highs to climb into
the mid to upper 60s. Light winds on Tuesday will make for a
wonderful fall day across the North Country.

&&

.SHORT TERM /TUESDAY NIGHT THROUGH WEDNESDAY NIGHT/...
As of 310 AM EDT Monday...High pressure will slowly build south of
the region through midweek, keeping conditions dry. South to
southwest winds will become breezy on Wednesday, allowing
temperatures to warm back to above normal. Low pressure will scoot
by to our north late Tuesday night into Wednesday, but best moisture
and forcing will remain north of the international border, so don't
anticipate more than just mid-high clouds. Precipitation chances
will begin to increase late Wednesday night as the low drags its
attendant cold front eastward through the Great Lakes, but bulk of
any showers will hold off until well after midnight.

&&

.LONG TERM /THURSDAY THROUGH SUNDAY/...
As of 310 AM EDT Monday...Much of the extended will be fairly quiet,
with cold frontal passage for Thursday into Friday, followed by high
pressure. In spite of some lingering timing/placement differences,
model guidance has pretty much to come to a consensus on the details
of the frontal passage for Thursday. Although a thin band of
moisture will pool ahead of the front, the bulk of any moisture
associated with the remnants of Tropical Storm Sally will remain
shunted well to our south. Instability will be lacking as well due
to unfavorable frontal passage timing and poor lapse rates.
Therefore, don't expect much more than scattered showers with the
frontal passage. Drier air works in behind the front, so bulk of the
activity will wane Thursday night/early Friday. Canadian high
pressure will build over the North Country for later Friday and then
persist through the weekend. This will be a chilly and dry airmass,
so while clear skies and sunshine are expected, temperatures will be
below normal; highs could well stay in the 50s in most spots, and
overnight lows will drop into the lower to mid 30s in many
locations. Note that the latest CPC 6 to 10 day outlook calls for
below normal temperatures and drier than normal conditions, which
matches the above thinking well.

&&

.AVIATION /07Z MONDAY THROUGH FRIDAY/...
Through 06Z Tuesday...All sites are currently VFR with the
exception of KSLK where an overcast 2600 ft deck is currently
being observed. This one pocket of MVFR ceilings will remain
through around 10Z before improving to VFR with all sites
expected to remain VFR thereafter through the remainder of the
forecast period. A few gusts from the southwest will be possible
at the terminals through 08Z but we should see winds less than
10 knots prevail through the overnight hours. An uptick in winds
are expected once again late Monday morning into Monday
afternoon as we mix down about 20 knots of winds. Winds will
veer to the northwest by 12Z with winds remaining from the 
northwest through the forecast period.

Outlook...

Tuesday: VFR. NO SIG WX.
Tuesday Night: VFR. NO SIG WX.
Wednesday: VFR. NO SIG WX.
Wednesday Night: VFR. Chance SHRA.
Thursday: Mainly VFR, with local MVFR possible. Chance SHRA.
Thursday Night: VFR. Chance SHRA.
Friday: VFR. Chance SHRA.
