Area Forecast Discussion

233 AM EST Sat Nov 29 2025

.SYNOPSIS...
Lingering snow showers will continue to taper off through the
morning as high pressure builds into the region, bring cold and
drier weather for today. A low pressure system will arrive Sunday,
bringing some light snow accumulations to much of the area, with a
transition to rain expected within the valleys. An active wintry
weather pattern will continue behind it to kick off December, with
another system expected to impact the region Tuesday night into
Wednesday.

.NEAR TERM /THROUGH SUNDAY NIGHT/...
As of 132 AM EST Saturday...A cool and relatively dry day is expected
across the region today as as high pressure briefly builds over the
region, bringing a short break in the active weather pattern.
Lingering showers across the region will continue to taper off
through the morning, with dry conditions prevailing for the majority
of the day. Skies should gradually clear through the day, with most
locations having a chance of seeing blue skies, albeit brief as high
clouds associated with the low pressure system will begin to stream
into the region late today. Daytime highs will be on the cool side
today, with temperatures only in the upper 20s to mid 30s.

The next system will quickly arrive early Sunday morning, with the
low tracking out of the Great Lakes up the St. Lawrence Valley,
bringing another round of widespread precipitation. Precipitation
looks to start as snow across the region, but warm southerly flow
will allow for temperatures to warm enough in the broader valleys
that any snowfall should quickly transition to rain, while the
mountains should remain snow throughout the event. Snowfall amounts
will be light, with a few inches expected in the higher terrain. In
addition to the precipitation, winds will be on the breezy side
Sunday with a low level jet overhead, with gusts of 25 to 40
mph possible, especially in the Champlain Valley due to
channeling. Temperatures during the day Sunday will generally in
the 30s to low 40s, with overnight lows dropping into the teens
and 20s as the system pulls away from the region.

.SHORT TERM /MONDAY/...
As of 132 AM EST Saturday...Cool and quiet weather is expected during
the day Monday as another brief period of high pressure builds into
the region in between systems. High temperatures on Monday look to
only climb into the 20s to low 30s, with most locations struggling
to get above freezing. Dry weather and lighter winds are expected
throughout the day, with a few chances for some blue skies in the
afternoon.

&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
As of 205 AM EST Saturday...There are two notable weather
producing systems depicted in model guidance next week. The
initial focus remains on Tuesday for the formation and rapid
deepening of an offshore low that would likely bring some
accumulating snowfall to portions of northern New York and
Vermont. Overwhelmingly, model probabilities favor an unblocked
pattern than would sharply limit residence time of any system,
but all suites do show some accumulations being likely. Best
chances for impactful amounts remain across southern/central
Vermont with more token amounts northward and westward. The
track of the low will be key in determining snowfall amounts,
but around 4 inches or a little more for southern/central
Vermont continues to fall into reasonable expectation at this
point given 40-55% likelihood per NBM 24hr accumulation
probabilities; chances of greater than 7 inches for southern
Vermont around in the 30-40% range at this time. Should the
track edge northward, likelihoods will increase. Temperatures
are favored to range from the lower 30s for highs to lower 20s
for lows through Wednesday night.

The second notable system is a probable arctic front in the
vicinity of Thursday. Model guidance continues to depict a
sharp frontal boundary bringing colder temperatures across the
region later next week. This pattern typically favors more
squall-like showers potentially forming along a line sweeping
through the region. Thermal signatures are strong this far out
and point to the potential for an even sharper cooldown with
lows potentially in the single digits around zero and wind chill
values below zero. The pattern will likely stay active late
week into the weekend with large-scale blocking highly unlikely
and longwave troughing trending over the Northeast.


&&

.AVIATION /06Z SATURDAY THROUGH WEDNESDAY/...
Through 06Z Sunday...Snow showers continue mainly in upslope
locations and in northeastern Vermont keeping some IFR
conditions going at EFK and MVFR CIGs at SLK. Showers are more
conditional at BTV/RUT/MPV with PROB30 groups covering scattered
coverage through 9Z as drier air continues to work into the
region. By 12Z, snow showers should be trending sharply downward
with intermittent MVFR CIGs possibly continuing at EFK, and
slow improving MVFR CIGs at SLK through 18Z. Some gusts to 20kts
will continue overnight before high pressure moves in allowing
the pressure gradient and winds to relax.

Outlook...

Sunday: Mainly MVFR and IFR, with areas VFR possible. Windy with
gusts to 30 kt. Definite SN, Definite SHRA, Definite SHSN.
Sunday Night: Mainly VFR, with areas MVFR possible. Chance SHRA,
Chance SHSN.
Monday: Mainly VFR, with local MVFR possible. Slight chance SHSN.
Monday Night: VFR. NO SIG WX.
Tuesday: Mainly VFR, with areas MVFR possible. Chance SN.
Tuesday Night: Mainly VFR, with areas MVFR possible. Chance SN.
Wednesday: VFR. NO SIG WX.

.MARINE...
A Lake Wind Advisory remains in effect this evening and into
Saturday morning. Looking for W to WNW winds to remain elevated
through Saturday morning due to steep lapse rates over Lake
Champlain and moderately strong gradient flow. Sustained winds
will generally be in the 15 to 30 KT range and peak gusts will
be to around 35 KTs during the pre-dawn hours Saturday. Waves
will likely remain about 2 to 4 feet, before decreasing toward
the mid-day hours Saturday.

&&

.EQUIPMENT...
NOAA Weather Radio station WXM-44, transmitting from Mt.
Ascutney, Vermont, on frequency 162.475 MHz is non-operational
at this time. NWS technicians have diagnosed the problem, but
repairs will likely not be able to occur for quite some time due
to circumstances beyond our control. Therefore, the time of
return to service is currently unknown. The following NOAA
Weather Radio transmitters may be able to provide service during
this outage: WWG 50 from Burke Mtn, VT at 162.425 MHz and WNG
546 from Hanover, NH at 162.525 MHz.

Equipment malfunctions at the Colchester Reef meteorological
station will likely leave it inoperable for an extended period
of time. This site is not serviced by the NWS. Technicians do
not currently have an estimated return to service for this
station. Use extra caution when navigating the broad waters of
Lake Champlain, and please contact us if you observe winds
significantly deviating from the forecast.
