Area Forecast Discussion
National Weather Service Burlington VT
306 AM EST Tue Jan 31 2023
.SYNOPSIS...
An arctic front will bring scattered snow showers early this
morning, with a dusting to an inch of snowfall possible across
northern New York and Vermont early this morning. The arctic
front will be followed by clearing skies for the balance of the
day. Northwest winds will become light tonight, allowing for a
cold night across the region. Winds shifting into the south and
southwest will allow for briefly milder conditions Wednesday and
especially Thursday. However, the coldest air mass of the
season will arrive with another arctic front Thursday night into
Friday, with bitterly cold temperatures and dangerously low
wind chill values. The extreme cold will be relatively short-
lived, with temperatures moderating during the day on Sunday,
and trending back above seasonal averages for next week.
&&
.NEAR TERM /THROUGH WEDNESDAY/...
As of 300 AM EST Tuesday...A shallow arctic front moving through
the St. Lawrence Valley at 08Z will shift sewd early this
morning into our region. Air mass is relatively dry in advance
of the front with PW values 0.15-0.25". However, the combination
of frontogenetic forcing and favorably deep saturation in the
dendrite growth layer will promote snow shower activity for a 1-3
hour period early this morning as front progresses from NW-SE.
Overall, looking for just a coating to 1" of snowfall thru 12Z
or so, and with sfc/road temperatures already well below
freezing, not expecting much impact in terms of icy road
conditions. Overall snow will be dry in character with SLRs 15:1
to 20:1.
With the front, surge of colder 925mb temperatures is expected
09-15Z from NW-SE, with 925mb temperatures falling to -16 to
-18C across northern sections. Despite clearing skies mid-late
morning, sunshine will be rather ineffective with the low-level
CAA, and looking for highs in the mid-upper teens across nrn
sections (lower teens across the St. Lawrence Valley). Later
arrival of frontal zone across s-central VT will allow for low-
mid 20s across Rutland and Windsor counties this morning.
Surface high pressure brings diminishing winds and good
radiational cooling conditions for tonight. May see some high
clouds across the southern half of the CWA, so that may mitigate
the radiative cooling somewhat across the south. In general,
looking for lows near zero in the Champlain Valley, and zero to -10F
for the northern Adirondacks, St. Lawrence Valley, and
central/nern VT. Should see single digits above zero across
s-central VT.
No significant weather for Wednesday. However, as surface ridge
axis settles to our south, A SW-WSW flow from lake Ontario will
bring an increase in clouds and a 30-40% chance of snow showers
across southern St. Lawrence into southern Franklin NY counties.
A light snow accumulation of a dusting to 1" is possible across
southern St. Lawrence and Franklin counties Wednesday, mainly
along and south of NY State route 3. May see some clouds in
4-6kft layer extend/advect newd into the Champlain Valley and
into the northern Green Mtns Wednesday afternoon, with a few
mountain snow showers or flurries possible. Temperatures will
moderate slightly on Wednesday, with highs generally in the
upper teens across the northern Adirondacks and northeastern
Vermont, and into the 20-25F range elsewhere across the North
Country.
&&
.SHORT TERM /WEDNESDAY NIGHT THROUGH THURSDAY NIGHT/...
As of 306 AM EST Tuesday...Relatively mild conditions Wednesday night
will start to give way on Thursday in advance of the weekend's
arctic front. Wind speeds will increase from west to east across our
area Thursday with maximum gusts approaching 20kts in the valleys
with higher speeds in the mountains. This shift in winds should put
an end to the chance of lake effect snow showers in Saint Lawrence
county, but we will see chance POPS begin to sag down from the
international border throughout the day Thursday. Don't get too
excited however, as accumulations are expected to be minimal.
&&
.LONG TERM /FRIDAY THROUGH MONDAY/...
As of 306 AM EST Tuesday...The most significant weather of our
forecast period will begin to move in to our area on Friday, with
temperatures dropping down into the single digits Fahrenheit by
Friday morning before plummeting to dangerously cold levels on
Saturday. Northern New York and the NEK could be in store for
surface temperatures more than 20 degrees below zero while the
Champlain valley is looking to by "only" in the negative teens.
These cold temperatures combined with winds gusting to near 20kt can
cause frostbite with just 10 minutes of exposure, so we will be
messaging safety early and often with this system. The good news is
it appears this will be a quick hitter as the arctic air moves off
by Sunday and temperatures return to near normal levels for the
beginning of next week.
&&
.AVIATION /08Z TUESDAY THROUGH SATURDAY/...
Through 12Z Wednesday...Arctic boundary crossing the region
from NW to SE between 07-14Z will bring periods of MVFR/IFR
snow showers for a period of 1-3 hours. Light snow accumulation
of a coating to 1" will bring minor impacts to aviation ground
operations, but overall character of the snowfall will be
light/dry. Should see a gradual clearing and a return to VFR
conditions as arctic front pushes south of KRUT by 14Z or so.
Light and variable winds at 06Z become NW around 10kt with
frontal passage, with a few gusts 16-18kts this morning.
Pressure gradient diminishes rather quickly this afternoon and
evening, with NW winds decreasing to 5-10kts and eventually
light and variable late this evening and overnight.
Outlook...
Wednesday: VFR. NO SIG WX.
Wednesday Night: VFR. Slight chance SHSN.
Thursday: VFR. Windy with gusts to 30 kt. Slight chance SHSN.
Thursday Night: VFR. Slight chance SHSN.
Friday: VFR. NO SIG WX.
Friday Night: VFR. NO SIG WX.
Saturday: VFR. NO SIG WX.
