Area Forecast Discussion
National Weather Service Burlington VT
756 PM EDT Mon Oct 13 2025

.SYNOPSIS...
Scattered showers will continue across the region through this
evening as low pressure spins off the New Jersey coast, eventually
pushing eastward on Tuesday. Cool, breezy, and dry conditions will
prevail through much of the remainder of the week. We trend warmer
for the weekend, with our next chance for widespread rain not
arriving until early next week.

&&

.NEAR TERM /THROUGH TUESDAY NIGHT/...
As of 207 PM EDT Monday...Showers have become a bit less widespread
this afternoon, particularly across south-central VT where radar
shows little/no activity. Moisture and waves of showers will
continue to rotate around the low as it remains near the NJ coast
through tonight, so anticipate there will be periods of rain mixed
with drier intervals over the next 12-18 hours. Rain will remain
light in nature though, so it won`t be a washout by a long shot. In
fact, have continued the trend of lowering total QPF amounts; latest
forecast now has the vast majority of our forecast area receiving
less than a half inch, with the highest amounts to remain across
south-central VT. Temperatures will remain fairly steady in the
upper 40s to mid/upper 50s through this afternoon, then dropping
into the upper 30s to upper 40s overnight.

Any lingering showers will quickly come to an end Tuesday morning as
the coastal low starts to pull away from the eastern CONUS. Light
north flow will develop by the afternoon/evening, along with partly
to mostly cloudy skies. Highs will be a little warmer than today,
mainly in the 50s to low 60s, warmest in the St Lawrence Valley. A
cold front will then cross from northwest to southeast Tuesday
night, ushering in a cooler and drier airmass. Winds will turn to
the north/northwest, and while moisture will quickly decrease, there
could be enough to allow a few showers to develop as the front moves
through, particularly in the higher terrain of the northern
Adirondacks and northern Greens. Temperatures will drop into the
low/mid 30s in the Adirondacks and Northeast Kingdom, so a bit of
snow will be possible over the mountain summits. Otherwise, lows
should be in the upper 30s to mid 40s.

&&

.SHORT TERM /WEDNESDAY THROUGH WEDNESDAY NIGHT/...
As of 207 PM EDT Monday...High pressure will gradually build into the
Great Lakes while low pressure exits eastward out over the Atlantic.
Cold air advection will prevail on brisk north/northwest winds;
highs will only top out in the upper 40s to mid 50s on Wednesday. An
upper shortwave trough will swing southward out of Quebec, but with
very dry air in place, don`t anticipate much beyond increased cloud
cover, particularly over northern and eastern VT. Gusts of 20 to 30
mph are expected, strongest in the Champlain Valley as winds due to
channeling. Minimum relative humidity will generally be 35 to 45
percent, keeping fire weather conditions sub-critical. Wednesday
night will be cold, though there should be enough remaining wind
overnight to preclude optimal radiational cooling conditions. Lows
will be in the mid/upper 20s to low 30s in the Adirondacks, St
Lawrence Valley, Northeast Kingdom, and eastern VT, while remaining
32 to 40F across the remainder of the forecast area.

&&

.LONG TERM /THURSDAY THROUGH MONDAY/...
As of 129 PM EDT Monday...Closed upper level low pressure centered
over Nova Scotia on Thursday will produce a strong northerly flow
across the forecast area with an 850mb jet of 40-45 knots and drier
air mixing down towards the surface. This may result in 10-20 mph
winds and 20-25 mph gusts, potentially even higher, 30-35 mph, on
north-south aligned valleys like the Champlain Valley as well as on
exposed higher terrain. Due to the dry air mixing efficiently down
to the surface, we`re forecasting relative humidity values to bottom
out around 30-40%, and combined with the gusty winds, this continues
to raise some concerns for critical fire weather conditions late
week. Temperatures will also be colder than seasonal normals during
the latter half of the week due to the influx of northern air with
highs only in the upper 40s and 50s and overnight lows in the 20s to
lower 40s.

Brief, multi layer ridging is anticipated for Saturday, allowing one
more mainly dry day and daytime temperatures to reach back into the
upper 50s to mid 60s before a modestly deep trough digs into the
region from the west and associated surface frontal system early
next week, bringing increasing chances of precipitation (up to 55-
75% chance Sunday night). Sunday is likely the warmest day of the
long term forecast period as warm southerly flow brings highs into
the 60s, then temperatures are expected to dip again with highs in
the mid 50s to lower 60s to start the work week with the upper level
low nearly overhead. Lows will largely fall into the mid 30s to
upper 40s early next week.

.AVIATION /00Z TUESDAY THROUGH SATURDAY/...
Through 00Z Wednesday...A large majority of the area has come
under a stout dry slot which has limited the precipitation and
lower ceilings at all terminals. While all terminals are
currently VFR, a general trend towards MVFR is expected at all
terminals outside of MSS. Terminals across far southern Vermont
and southern New Hampshire have already lowered to high MVFR
which indicates, while not currently in place, low level
moisture should be able to move northward over the next few
hours. Dry air should be able to hold off this moister air
until at least 06Z, when all terminals outside of MSS should
fall to 2000-3000ft agl. RUT will be the first terminal to see
MVFR, with a tempo group for the next few hours as ceilings
lower. IFR probabilities have decreased with currently large
dewpoint depressions, however, an hour or 2 of low MVFR
1000-2000ft agl ceilings cannot be ruled out at SLK/RUT between
09 and 13Z. Breezy winds to 10 knots at RUT, and LLWS from a
30-40 knot low level jet at 2000ft agl, will continue at RUT and
MPV until 06Z, when the low level jet should weaken.
Precipitation over the course of the night will be light to just
a drizzle or a light shower with rates not warranting any
mention of visibility restrictions.

One note is that current moisture pooling along the western
bank of Lake Champlain has resulted in a scattered to broken
1000 deck at PBG. It is uncertain whether this is a result of a
lake cloud or simply pooling moisture. A tempo was used at PBG
until 04Z for these lower ceilings to 1000ft agl. Drier
northerly air should be able to scour out this low level
moisture by 05Z. All terminals should remain MVFR through at
least 14Z when the coastal system shift eastward with drier air
entraining in from the north. Terminals will look to improve
back to VFR beyond 18Z tomorrow.

Outlook...

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