Area Forecast Discussion
National Weather Service Burlington VT
406 AM EST Sun Dec 31 2017

.SYNOPSIS...
Another surge of very cold air moves into the region today
through New Years Day accompanied by gusty northwest winds. This
will result in dangerously cold wind chills to end the year and
start of 2018. Little change is expected in the overall pattern
for the upcoming week with below normal temperatures...but
another surge of arctic air moves down into the region next
Friday and Saturday for more wind chill issues.

&&

.NEAR TERM /THROUGH MONDAY/...
As of 406 AM EST Sunday...All wind chill warnings and 
advisories remain in effect now through noon on New Years Day.

Colder air continues to move back into the region early this 
morning on northwest flow aloft. West to northwest surface winds
later this morning and afternoon will be gusty enough to 
produce wind chill concerns with values in the 15 to 30 below 
range. Then as even colder air moves in tonight...the winds will
not be as strong as during the day...but enough to produce even
colder wind chills with values in the 20 to 40 below range. As 
a result...all wind chill warnings and advisories remain in 
place now through midday on New Years Day. High temperatures 
today and New Years Day will be from 5 above to 5 below and low 
temperatures tonight will easily be 10 to 20 below with some 25 
below readings in the mountains.

&&

.SHORT TERM /MONDAY NIGHT THROUGH TUESDAY NIGHT/...
As of 406 AM EST Sunday...Looking at mainly dry conditions for 
Monday night as the aforementioned upper trough shifts east of 
the forecast area and is replaced by a narrow upper ridge. 
Blocked northwest flow will keep a good amount of clouds around 
though, especially in the upslope regions of the Adirondacks and
northern Greens, which may limit how far temps drop. With mean 
925mb temps in the -20 to -25C range though, lows in the 
negative teens to perhaps -20F still look reasonable. 

A welcomed albeit brief respite from the arctic chill starts Tuesday 
and continues into Tuesday night and Wednesday as northwest flow 
gradually backs to the southwest in response to another arctic 
trough and associated surface clipper low digging into the Great 
Lakes. Temps will warm significantly from overnight lows into the 
single digits east to mid teens west with some lake effect snow 
showers likely downwind of Lake Ontario into portions of the 
southern St. Lawrence Valley and western Adirondacks. Overall QPF 
isn't too impressive with resulting snowfall accumulations generally 
in the 1-3" range, possibly drifting as far northeast as Jay
Peak.

&&

.LONG TERM /WEDNESDAY THROUGH SATURDAY/...
As of 406 AM EST Sunday...As the aforementioned upper trough 
continues to dig southeastward into the eastern Great Lakes, 
southwest flow amplifies over the Northeast allowing temps to 
climb further into the teens and 20s on Wednesday. The surface 
clipper low looks to weaken through time and the surface flow 
trends a little more south allowing lake effect to shift 
northwest of the St. Lawrence River during the day, but as the 
trough shifts east into the forecast area Wednesday night lake 
effect will likely redevelop. At the same time, low pressure 
bombing out well east of North Carolina will rapidly track 
northeast Wednesday night into Thursday with consensus amongst 
the GEM and ECMWF showing the surface and 700mb low curling 
northwest into coastal Maine allowing some moisture to wrap 
around into eastern portions of Vermont and New England Thursday
afternoon through Friday morning. Being on the western edge of 
the deep moisture, QPF will be light if this solution pans out, 
but could see accumulations in the 3-6" range east of the Greens
over the 24-hr period.

Conditions for the end of the week into the weekend continue to just 
absolutely brutal as another surge of arctic temperatures moves into 
the region with 925mb temps bottoming out in the -30 to -35C range 
across our entire CWA Friday night. Highs may not top 0F both Friday 
and Saturday, and lows Friday night could be the coldest we've seen 
yet in the -20 to -35F range. Couple this with potentially strong 
northerly winds between the departing coastal low and strong high 
pressure building over central Ontario and we may be looking at 
widespread wind chills in the -30 to -40F range.

&&

.AVIATION /09Z SUNDAY THROUGH THURSDAY/...
Through 06Z Monday...Areal coverage of clouds and lingering snow
showers continues to diminish fairly quickly over the area early
this morning and essentially looking at VFR conditions for much
of the period. Winds are generally light and variable early this
morning and after 12z will generally be from the west and
northwest at speeds around 10 knots. 

Outlook...

New Years Day: VFR. NO SIG WX.
Monday Night: VFR. NO SIG WX.
Tuesday: Mainly VFR, with local MVFR possible. Chance SHSN.
Tuesday Night: Mainly VFR, with areas MVFR possible. Slight
chance SHSN.
Wednesday: Mainly VFR, with local MVFR possible. Chance SHSN.
Wednesday Night: Mainly VFR, with local MVFR possible. Slight
chance SHSN.
Thursday: Mainly VFR, with local IFR possible. Chance SHSN.

&&

.EQUIPMENT...
The KTYX (Montague NY) radar will be out of service this weekend
and possibly early next week as a motor and power supply have 
failed. Parts are on order and are scheduled to arrive soon.

&&

.BTV WATCHES/WARNINGS/ADVISORIES...
