Area Forecast Discussion
National Weather Service Burlington VT
1247 AM EST Wed Dec 24 2025
.SYNOPSIS...
A clipper system will continue to bring steady light snow
today, continuing into tonight and early Wednesday. Several
inches of snow accumulation will likely bring at least some
minor winter travel impacts. Quieter conditions are expected for
Christmas Eve and Christmas Day, though a few mountain snow
showers will continue to be possible. Thereafter, the next
chance for widespread precipitation is not expected to arrive
until Sunday, when mixed wintry precipitation is possible across
the North Country.
&&
.NEAR TERM /THROUGH THURSDAY/...
As of 100 PM EST Tuesday...Light stratiform snow is lifting
into our area from the west. Thus far snowfall has been light
and is expected to continue to spread eastward this evening.
Snowfall rates should remain light with around 1 inch of
snowfall or less per 3 hour block of time. Greatest
accumulations should occur between 20-02z. Travel may be
impeded this evening due to the ongoing snow accumulating.
Surface low will track right across our CWA, then east of the
area by about 09z early Wednesday morning. After the low slides
east of us, snowfall will become more upslope driven and linger
into the day Wed. The higher summits will see some additional
accumulations. Temperatures overnight will stay fairly mild with
ongoing snowfall and cloudy skies, generally bottoming out in
the 20s areawide. Temperatures on Wed will reach the mid 20s to
mid 30s. Colder air moves into the area Wednesday night and as
snow showers come to an end, minimum temperatures will dip into
the teens areawide.
&&
.SHORT TERM /THURSDAY NIGHT THROUGH FRIDAY/...
As of 100 PM EST Tuesday...For Thursday a weak surface feature
as well as some upper level shortwave energy move just north of
the international border. We will have some scattered light snow
showers, with better concentration in the higher peaks of the
Adirondacks and northern Greens. May see a coating to 2" of
snowfall, highest across far n-central VT, associated with the
snow showers Christmas day. High temperatures on Christmas Day
again in the 25 to 30F range for most areas, with winds becoming
NW 10-15 mph during the afternoon hrs following the passage of
the front. Thursday night will be cold with minimum temperatures
dropping into the single digits above and below zero as high
pressure ridges into our area from Canada, and conditions become
ideal for radiational cooling with drier air moving into our
area.
&&
.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
As of 1246 AM EST Wednesday...Our active pattern continues through
the long term, with some form of system coming through every 36
hours or so. Saturday will have a Clipper passing to our south. The
models have consistently been showing this system delivering an
almost glancing blow as it moves too far south to pack too much of a
punch, but what precip does fall will be in the form of snow as
temperatures stay below freezing throughout the CWA. The most
impactful system of the forecast period will come by Sunday night.
Plenty of uncertainty remains with this system, which will likely
have some form of mixed precipitation. We continue to see a split
between the ECMWF and GFS systems, with the ECMWF showing a warmer
solution that would bring in more sleet with the potential for
freezing rain while the GFS would be a primarily snow forecast. As
the system moves off to the east, we look to get some more snow
lingering on the backside lasting through the day on Monday. .
&&
.AVIATION /06Z WEDNESDAY THROUGH SUNDAY/...
Light snow is continuing to move through the CWA along a trough. The
trough will pass through the terminals in the next several hours,
switching the winds from southerly to northwesterly. After the
trough passes, snow will die down and leave us with primarily MVFR
conditions through the overnight hours. BKN MVFR skies will persist
into the day tomorrow. &&

.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.
The Colchester Reef meteorological station is out of service.
This site is not serviced by the NWS and there isn`t an
estimated return to service at present. Use extra caution when
navigating the broad waters of Lake Champlain. Please contact us
if you observe winds significantly deviating from the
recreational forecast.
