Area Forecast Discussion
National Weather Service Burlington VT
1239 PM EST Fri Jan 17 2025

.SYNOPSIS...
A ridge of high pressure builds in today. Saturday we'll see
our next system bringing some snow and strong, gusty winds to
our forecast area. Next week is shaping up to be some of the
coldest air we have seen this season with wind chills reaching
down below -10F Tuesday and Wednesday.

&&

.NEAR TERM /THROUGH SATURDAY/...
As of 1225 PM EST Friday...Conditions are mostly cloudy to
overcast with intervals of non-accumulating flurries. There's
little to report in terms of forecast changes. Just a quiet
mid-January day.

Previous discussion...A ridge will build over the area today,
making it the last best day to be outside for a while.
Temperatures will threaten to rise above freezing in valley
locations, with higher elevations reaching into the 20s. A low
pressure system tracking through Hudson Bay and the trailing
cold front will impact us starting Friday evening. Winds will
begin to strengthen out of the southwest and temperatures will
warm during the overnight hours. The winds will be the main
event on Saturday, with channeling in the CPV bringing gusts
near 40kts for much of the day. The higher elevations in the ADK
and Greens will see even stronger winds. While the frontal
system doesn't have a lot of associated moisture, we will see up
to a tenth of an inch of precip falling throughout the day. The
snow level will be between 1,000 and 1,500 feet in the warm
sector. After the front passes over, precip will quickly come to
an end.

&&

.SHORT TERM /SATURDAY NIGHT THROUGH SUNDAY NIGHT/...
As of 327 AM EST Friday...A cold front will quickly cross the region
Saturday night, bringing snow showers to an end by Sunday morning.
Additional snow amounts of an inch or two are possible. We'll see a
brief break in the precipitation on Sunday, but then more snow will
spread northward late in the day into the overnight. This is in
response to low pressure which will develop off the Delmarva and
lift toward Cape Cod Sunday night, then quickly push northeast
toward Nova Scotia by Monday morning. Latest probabilistic guidance
continues to be quite meager in its snow amounts with this fast-
moving system; 24-hr snow amounts of greater than 2 inches are only
25-30% at best over southeastern VT, dwindling down to 10% or less
along/northwest of a Ticonderoga-Burlington-Newport line. Sunday
will see highs in the mid teens to mid 20s, but Sunday night starts
our cooling trend. Colder air will start to spread in for early next
week, and lows Sunday night will be -5F to +5F. Winds will be a
little breezy Sunday night as well, resulting in wind chills at or
below zero areawide.

&&

.LONG TERM /MONDAY THROUGH FRIDAY/...
As of 327 AM EST Friday...The main focus for much of next week will
be very cold conditions as a strong arctic high builds into the
Upper Midwest and pushes eastward into the eastern CONUS. 850mb
temperatures will drop as low as -25C at the height of the cold,
while 500-1000mb thicknesses approach sub 490dam. Daytime highs will
only be in the single digits to low teens Monday through Wednesday,
while overnight lows will be well below zero in many locations. Also
of concern will be the potential for gusty winds, mainly on Tuesday
afternoon, when gusts of 20 mph will be possible due to steepening
lapse rates. The result will be wind chills of 5 to 15 below zero
Tuesday afternoon, with the higher summits likely seeing wind chills
as cold as -25F. Expect the weather to generally remain dry through
this period, though a lake effect band will likely be waffling
around the east end of Lake Ontario, lifting into the northern
Adirondacks from time to time, perhaps even streaming eastward into
the northern Greens.

We'll finally start to see some improvement Thursday as the ridge
axis moves east and we get back into south/southwest flow. Any lake
effect band off of Lake Ontario will push northward across the St
Lawrence Valley. Temperatures will remain below normal on Thursday,
but should warm up into the mid teens to mid 20s.

&&

.AVIATION /18Z FRIDAY THROUGH WEDNESDAY/...
Through 18Z Saturday...Conditions are a mix of mainly MVFR and
VFR due to 1800-3000 ft agl ceilings. Saranac Lake remains about
500 ft agl though. It briefly reported BR, but it was likely
very light snow. Ceilings are expected to improve in the next
couple hours across most terminals, but may linger at KSLK.
South to southwest winds at 5 to 10 knots will begin to become
south to southeast and increase beyond 00-03z up to 8 to 14
knots sustained, with higher winds mainly in the Champlain
Valley. Areas of LLWS will spread over the region as southwest
winds at 2000 ft agl increase to 40 to 45 knots for most
terminals. Surface winds and gusts will likely peak between 12z
and 18z Thursday. Most areas will have sustained winds 10 to 15
knots, but at KBTV, it will likely be near or at 20 knots with
gusts 30 to 35 knots. Precipitation will approach from the west
after 18z Saturday, along with gradually decreasing winds.

Outlook...

Saturday Night: MVFR/IFR conditions possible. Chance SHSN.
Sunday: VFR. Slight chance SHSN.
Sunday Night: Mainly VFR, with local MVFR possible. Chance SHSN.
Martin Luther King Jr Day: VFR. Slight chance SHSN.
Monday Night: VFR. NO SIG WX.
Tuesday: VFR. Slight chance SHSN.
Tuesday Night: VFR. NO SIG WX.
Wednesday: VFR. NO SIG WX.
