Area Forecast Discussion
National Weather Service Burlington VT
324 AM EST Mon Jan 30 2023
.SYNOPSIS...
Light snow will overspread the North Country this afternoon and
continue into tonight with snowfall accumulations ranging from a
dusting to an inch or two in the mountains by Tuesday. Temperatures
will trend cooler for the start of the work week, but an arctic
blast of bitterly cold temperatures and dangerously cold wind chills
will impact the area Friday into Saturday. Wind chill warnings will
likely be needed during this time frame for the entire North Country.
&&
.NEAR TERM /THROUGH TUESDAY/...
As of 323 AM EST Monday...Sfc cold frnt is slowly dropping acrs
southern Windsor County, as VSF is still 40F as of 3 AM, but expect
wind shift and temps to drop quickly in the next 1 to 2 hours.
A widespread light snowfall is expected this aftn into tonight with
snowfall amounts of a dusting to an inch or two likely. Water vapor
shows northern stream s/w energy crossing the northern Great Lakes
this morning with a ribbon of enhanced mid lvl moisture. This
forcing and moisture wl arrive acrs our western cwa around 18z and
quickly spread east acrs most of VT by 00z. Have bumped pops into
the likely/low cat range to cover this potential and have worded the
precip as light snow. RAP sounding data does indicate >90% RH in the
DGZ with weak uvv couplet, supporting the idea of good flake size
for a period of time late this aftn/evening. Snow ratios 15/18 to 1
range this evening. Meanwhile, secondary surge of modified arctic
air drops south acrs our cwa btwn 06z-09z Tues, supporting another
round of light snow shower activity. Progged 850mb temps drop
between -16C and -20C behind this boundary by 12z Tues, helping to
squeeze out remaining moisture in the mtns. A period of upslope snow
showers is likley with boundary, but 925mb to 850mb winds are
relatively weak in the 20 to 25 knot range and associated uvvs
within this layer are minor, so idea of light snow showers looks
good. Interesting, high res data does indicate brief period of light
snow locally near BTV late tonight into early Tues, from boundary
and some lake enhanced moisture from Lake Champlain. Combining the
two minor events, supports generally a dusting to 2 inches with
localized 3 or 4 inches possible from Mansfield to Jay Peak by 12z
Tues. Tuesday we should see increasing amounts of sunshine, as much
drier air advects into the region on northwest winds. Some lingering
flurries possible in the mtns, but the main story wl be the much
colder temps. Highs only in the single digits summits to mid teens
CPV/SLV with lower 20s parts of the CT River Valley on Tues,
supported by 850mb temps btwn -10C se zones to -20C near
International Border.
&&
.SHORT TERM /TUESDAY NIGHT/...
As of 323 AM EST Monday...We will get some below normal temperatures
Tuesday night as skies clear behind a cold front. 925mb temperatures
look to be around - 15F, which will allow surface temperatures to
fall at least into the single digits. The NEK appears to get the
worst of the cold and is currently on schedule for temperatures to
fall below 0F. Southwesterly flow along Lake Ontario could develop
and bring some light lake effect snow to Saint Lawrence County in
the overnight hours.
&&
.LONG TERM /WEDNESDAY THROUGH SUNDAY/...
As of 323 AM EST Monday...Temperatures will rebound slightly
Wednesday and Thursday with a bit of warm air advection coming from
the south. St. Lawrence county could continue to see some light lake
effect snow through this time period as the flow continues to look
favorable coming off Lake Ontario. Chance POPS will spread along the
international border into the day on Thursday with the usual
upslopeareas favored.
The big story of the long term will be the bitingly cold arctic air
that sweeps into the region on Friday night. Confidence is high and
models are in good agreement that we will see temperatures fall 20
degrees below climatological normals. The Euro, for example, shows
925mb temperatures dropping below -30F for much of the area. In the
Champlain Valley we can expect low temperatures to reach -15F at the
surface while northern New York and the NEK could see temperatures
another 10 degrees colder. In addition to the cold temperatures,
wind gusts in excess of 20kt cover the entire CWA. If the current
forecast holds, we would expect wind chill warnings to blanket the
region. Extra caution will likely be needed to combat complacency
built up through what has been an abnormally warm winter thus far.
Beyond the headline of dangerous cold, we will see some snow showers
moving in with the arctic front on Friday and Saturday. As the front
moves past northern Vermont, the possibility of Lake Champlain
kicking out Lake Effect Snow will build.
The cold air will not linger over the North Country for too long as
a trough further west will kick it out by Sunday. Temperatures are
forecast to reach the upper 20s or lower 30s across our forecast
area by Sunday.
&&
.AVIATION /09Z MONDAY THROUGH FRIDAY/...
Through 06Z Tuesday...Its another battle with low clouds and
mainly MVFR conditions, except SLK which is crntly IFR. Have
followed a persistent type fcst with MVFR cigs prevailing at
most sites thru 12z, with some improvement possible at PBG/BTV
and MSS, while conditions bounce btwn MVFR and IFR at SLK thru
15z Monday. In addition, have a brief 2 hour tempo for -shsn and
IFR cigs at Rutland associated with fropa timing, based on
Middlebury obs of 2sm -shsn and overcast 900 feet agl. Winds
generally 5 to 10 knots with localized gusts 15 knots at MPV
thru early Monday. Widespread light snow develops after 18z with
periods of IFR vis and MVFR cigs likely btwn 18z-03z Monday.
Outlook...
Tuesday: VFR. NO SIG WX.
Tuesday Night: VFR. NO SIG WX.
Wednesday: VFR. NO SIG WX.
Wednesday Night: VFR. Slight chance SHSN.
Thursday: Mainly VFR, with local MVFR possible. Chance SHSN.
Thursday Night: Mainly VFR, with local MVFR possible. Chance
SHSN.
Friday: VFR. NO SIG WX.
