Area Forecast Discussion
National Weather Service Burlington VT
607 AM EST Thu Feb 1 2018

.SYNOPSIS...
A changeable weather pattern is in store for the remainder of
the week and into the weekend and early next week. An area of 
low pressure will affect the region overnight into Thursday. 
Expect some snow that will mix with light rain on Thursday as 
southerly winds bring in warmer air. A cold front will bring 
another round of cold weather to end the week. Another front is
expected to move through late Saturday with additional snow,
while yet another low pressure area on Monday gives us another
chance of snow.

&&

.NEAR TERM /UNTIL 7 PM THIS EVENING/...
As of 548 AM EST Thursday...Low level warming will cont as we go
later into the day. Later by afternoon a series of weak short
wave trofs aloft will result in intermittent lower terrain and 
scattered rain and snow showers, with all snow showers at and
above 1000 ft MSL. Snow accumulations even where precip type
remains all snow will be light, generally around an inch or
less except locally higher over favored mountain areas.

The arrival of the arctic front overnight tonight will likely 
result in another inch of snowfall with the possibility of brief
snow squall conditions with the immediate passage of the front. 
Still uncertain if we'll have the situation to actually issue 
our first "Snow Squall Warning" product. Later shifts will fine 
tune that aspect.

&&

.SHORT TERM /FRIDAY/...
Temperatures will remain steady or continue to fall. 925mb 
temperatures by Friday will be down to -20C near the Canadian 
border to -14C in the south by mid afternoon. Thus surface 
temperatures are not expected to move much during the day, and 
may actually slowly fall. Plan for highs only in the teens. 
Still a fairly tight pressure gradient, and good low level 
mixing, so we'll have breezy northwest winds gusting over 20 mph
quite often. That will produce wind chills much of the day in 
the -5 to -15F range. Still a good amount of low level moisture 
around, so I'd expect the mountains will squeeze out some light 
snows. Speaking of the mountains, air temperatures at the higher
elevations will only be in single digits, with winds producing 
wind chills well below zero (-20s to -30s, and pushing -45F at 
the highest summits).

Friday night is looking cold, but we've seen much worse earlier
this winter. Lows should range between +3 to -8F. Some wind 
will continue for much of the night, so wind chills will bottom 
out between -10F to -25F. We may end up having some wind chill 
advisory issuance requirements.

&&

.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
Should see a cold start to the weekend with 850mb temps of
-22C to -25C in place across the North Country and sfc ridge 
axis cresting across the region during Saturday morning. 
Generally looking at high temperatures of 15 to 20F Saturday 
afternoon with light westerly winds in place. It appears a weak 
frontal system developing across the Great Lakes will bring 
increasing clouds to the region later Saturday into Saturday 
night from SW-NE. Should see some developing light snow within 
the frontal zone, especially across nrn NY where we've increased
PoPs to around 60% for Saturday night, and 40-50% across VT. 
Based on present indications, may see light snow accumulations 
of 1-2" Sat night, with locally up to 3" possible across nrn NY.
The increasing clouds and light S-SW winds developing Saturday 
night will keep temperatures a bit warmer, with lows mainly in 
the low-mid teens. 

Next potential coastal low pressure system we are monitoring 
arrives Sunday night into Monday. Appears the 12Z GFS has 
shifted a bit further north and west with the sfc low tracking 
across Cape Cod/sern MA during Monday morning. The sfc low is
also a bit deeper at 990mb or so. On the other hand, the 12Z 
ECMWF has shown little change with prior runs with 999mb sfc low
tracking just south and east of the 40N 70W benchmark at 12Z 
Monday. Both operational runs indicate the system would be
rather quick moving, consistent with the open nature of the
associated 700-500mb shortwave trough. Appears best potential
for accumulating snow would be across central and eastern VT
Sunday night into Monday morning. The GFS solution would bring 
potential moderate snowfall (4-8") across central/ern sections 
of VT, and we'll need to continue to monitor this potl. At this 
point, have raised PoPs, to 60-70% across central/ern VT and 
45-60% elsewhere (lowest in the St. Lawrence Valley). Highs on 
Monday should be in the mid 20s. 

Should see continued seasonably cold temperatures into Tue/Wed
of next week, with highs generally in the low-mid 20s. The 12Z 
GFS suggests another potential shortwave trough and sfc low near
sern New England by Wednesday, but fast nature of the mid-level
flow pattern suggests timing of any features out at day 7 will 
be of relatively low skill at this point.

&&

.AVIATION /12Z THURSDAY THROUGH MONDAY/...
As of 439 AM EST...

Through 06Z Friday...Gusty southwesterly winds will continue 
this morning at MSS/SLK, while BTV/PBG will continue to see 
southerly winds channeled up through the Champlain Valley. 

The snow showers activity has diminished with the warm front, and 
expecting mainly VFR conditions until about noontime when a 
prefrontal trough ahead of a cold front approaches the northern NY 
TAF sites initially, and then the northern and central VT terminals 
in the afternoon. High MVFR cigs and vsbys will be possible in the 
snow showers. 

The cold front will follow in the late afternoon/evening periods 
with scattered snow showers and isolated snow squalls especially 
between 00Z-06Z/FRI. Late TAF issuances can pinpoint times.

The winds will veer to southwest to west in the late afternoon into 
the early evening at 10-15 kts with some gusts in the 18-25 kt 
range especially west of the Champlain Valley.

Outlook...

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