Area Forecast Discussion
National Weather Service Burlington VT
441 AM EST Thu Jan 4 2018

.SYNOPSIS...
Deep low pressure will track offshore and into the Canadian 
Maritimes by Friday bringing widespread light to moderate snow 
to the area. Behind this system, bitterly cold arctic air will 
surge back into the region along with sub-zero temperatures and 
dangerously cold wind chills for Friday into Saturday. 
Temperatures begin to moderate on Sunday, and warm considerably 
by Monday and Tuesday of next week as areas of light snow 
return.

&&

.NEAR TERM /THROUGH TONIGHT/...
As of 335 AM EST Thursday...The forecast largely remains on 
track as bombing low pressure off Cape Hatteras this morning 
tracks northeast toward the Bay of Fundy tonight while deepening
into the sub-960 mb range. Models have narrowed in on this 
general track over the past 24 hours and given the offshore 
solution near the benchmark our area will lie on the western 
periphery of steadier light to moderate snows. As such I've 
maintained Winter Weather Advisories for all areas except the 
Northeast Kingdom of Vermont where low-end warning level 
accumulations are expected. All and all we're looking at 18-hr 
accumulations ending at 12Z Friday to range from 0.5 to 3 inches
in the St. Lawrence Valley, 2 to 4 inches in the Adirondacks 
with some local enhancement on northwestern slopes, 3 to 6 
inches in the Champlain Valley including western Rutland County,
3 to 7 inches across southeast and east central VT, and 5 to 10
inches across the Northeast Kingdom. Of course there will be 
the customary variability, but this is the general picture. Of 
additional concern will be a tightly sharpening pressure 
gradient later today into tonight as the surface low swings by. 
This will boost northwesterly winds into the 10 to 20 mph range 
with 25 to 40 mph gusts and produce considerable areas of 
blowing snow. With the somewhat greater snowfall from the 
Champlain Valley eastward it will add another layer to the 
locally difficult travel this evening into tonight. 

In regard to temperatures, readings should top out by mid-afternoon 
in the teens to around 20 before the increasingly gusty north flow 
begins to temper values late. Embrace these values as they'll seem 
quite balmy by tomorrow and on Saturday. By later tonight arctic air 
surges back into the region as the surface low pushes toward the 
Gulf of St. Lawrence. Steadier snows should become increasingly 
orographic and confined to central and northern counties over time. 
Low temperatures to range from +/-5F from the Champlain Valley east 
and -5F to -12F across the Adirondacks and St. Lawrence Valley. With 
the aforementioned winds this will begin to create dangerously cold 
wind chill readings across the area. As such, we've upgraded the 
entire forecast area into a Wind Chill Warning. More on that
below.

&&

.SHORT TERM /FRIDAY THROUGH SATURDAY/...
As of 335 AM EST Thursday...The primary concern for Friday into
Saturday will be very low wind chills across the region. Light 
snows/snow showers will continue across the north through Friday
night, though coverage and dendrite size will gradually lessen 
over time with just some minor additional accumulations of a few
inches expected, mainly focused across the northern Greens. 
Northwest winds in the 10 to 20 mph range with gusts from 20 to 
30 mph will be likely during this period creating apparent 
temperatures from -25F to -45F. As such, Wind Chill Warnings are
in effect for the entire area through Saturday. Highs on Friday
won't go anywhere and remain steady or slowly fall through the 
day. Lows Friday night mainly in the -15 to -25F range - a touch
"warmer" than prior indications given persistent clouds and 
gradient flow. Saturday will be bitterly cold with highs from 
-2F to -8F in the St. Lawrence, Champlain and southern VT valleys 
with readings from -6F to -12F across the northern mountains and
north central/northeastern VT. Any lingering snow showers across 
northern counties will taper off over time. This will be a good 
day just to stay indoors.

&&

.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/... 
As of 400 AM EST Thursday...Continued cold temperatures are
expected for Saturday night as cold airmass remains in place.
Brisk northwest surface winds and very cold temperatures will
likely cause need for wind chill headlines through Saturday
night. Lows will range from about 15 to 30 degrees below zero.
Strong low level warm air advection returns for Sunday and
Monday with Southwesterly 850 mb jet around 40 to 50 kts. Clouds
will also be on the increase during this time period.
Temperatures warm into the teens on Sunday, upper 20s on Monday,
and even some 30s on Tuesday. Colder air will return again for
mid week. Sunday night into Monday will be our next chance for
some precipitation with low pressure system, along with warm
front out ahead and cold front trailing bringing some light
snow. Overall we remain in a pretty active weather pattern with
some bigger temperature ranges soon. 

&&

.AVIATION /09Z THURSDAY THROUGH MONDAY/...
Through 06Z Friday...VFR conditions will prevail through 12z
Thursday. Then expect things to deteriorate as widespread light
snow spreads northward. Snow will develop 12-16z Thursday, 
gradually reducing visibility to MVFR and eventually IFR at 
MPV/RUT/BTV by 21z. Ceilings will mainly remain at 1500-2500 ft 
from about 16z on. Light south winds this evening will turn to 
the northwest Thursday morning and increase through Thursday 
afternoon. This will result in blowing snow, with local IFR 
visibility possible at all TAF sites after 18z. Snow will be
ending during the overnight hours from west to east as well.  

Outlook...

Friday: Mainly MVFR and IFR, with areas VFR possible. Areas BS,
Likely SN, Chance SHSN.
Friday Night: Mainly VFR, with local MVFR possible. Chance SHSN,
Areas BS.
Saturday: VFR. Chance SHSN.
Saturday Night: VFR. NO SIG WX.
Sunday: Mainly VFR, with local MVFR possible. Slight chance SHSN.
Sunday Night: Mainly MVFR, with areas VFR possible. Chance SHSN.
Monday: MVFR and IFR. Likely SN.
