Area Forecast Discussion
National Weather Service Burlington VT
101 PM EST Wed Feb 5 2020

.SYNOPSIS...
High pressure building eastward from the Great Lakes will bring
partly sunny and seasonably cold conditions to the North Country
today. Much more active weather returns with a two-part winter
storm for Thursday and Friday. Snow overspreads the region
before daybreak on Thursday, switches to intermittent mixed
precipitation Thursday afternoon and night, and transitions back
to potentially heavy snow during the mid-day hours on Friday.
Snow will taper off to snow showers Friday evening. Winter
travels impacts will be likely for much of the area Thursday and
Friday. Much colder and drier conditions return for Saturday,
but temperatures quickly moderate back into the 30s for the
early to middle portion of next week.

&&

.NEAR TERM /THROUGH TONIGHT/...
As of 1258 PM EST Wednesday...No changes needed with this
update. Snow showers have ended across the area with diminishing
clouds across the Northeast Kingdom over the next couple hours.
Continues to shape up to be a really nice despite the chilly
temperatures. Expect temps to hold steady in the upper teens to
low 20s for the remainder of the afternoon.

Previous Discussion...Minor sky cover update to account for
partial clearing trends evident in surface observations and in
satellite data at sunrise. Should see skies trending partly to
mostly sunny by early afternoon. North winds at 10-15 mph will
subside to 5-10 mph this afternoon, but also help to offset
diurnal temperature trends. This will help to hold afternoon 2-m
temperatures in the low-mid 20s for most sections, except
25-30F across the valleys of Rutland and Windsor counties where
low- level CAA is slower to arrive this morning.

&&

.SHORT TERM /THURSDAY THROUGH FRIDAY/...
As of 342 AM EST Wednesday...A significant, two-part winter
storm is poised to affect the North Country Thursday and Friday
with better consistency noted in 00Z NWP guidance suite. Winter
Storm Watches have been posted across central/nrn VT and all of
nrn NY. Meanwhile Winter Weather Advisories have been posted for
Rutland/Windsor counties in VT.

All is quiet through midnight as high pressure translates ewd
into the Gulf of Maine. Will see an increasing mid-upper level
overcast overnight, so while temperatures will dip quickly into
the teens, readings should level off after midnight.

Steady snow is expected to overspread the North Country before
daybreak Thursday from SW-NE with leading surge of warm
advection and isentropic ascent. Widespread snowfall of 2-4" is
expected on the front end of the event, and will cause some slow
travel conditions, including for the morning commute. This
leading band of WAA and ascent lifts quickly north of our
region, so that by 18Z a mid-level dry slot is in place. There
is also a developing warm layer aloft, such that we'll see
periods of light intermittent sleet/freezing rain across much of
the region Thursday afternoon into Thursday night. This will
fall on top of already fallen snow, so the impact of the mixed
precipitation will not be particularly high. Could see up to a
tenth of an inch of ice accumulation, especially across
s-central VT. Highs on Thursday generally 28-34F, with
temperatures not falling much Thursday night.

For Friday, synoptic and mesoscale factors get increasingly
interesting and favorable for a period of heavy snowfall.
Primary mid- level trough and associated 500-250mb jet moves
newd from the TN River Valley, and induces strong sfc
cyclogenesis across the mid- atlantic states. The low deepens
rapidly while tracking along tightening 850mb frontal zone
across NJ/sern NY and central New England. The 00Z GFS, for
example, has a 976mb sfc low over swrn NH at 18Z Fri, and 972mb
near Portland, Maine at 00Z Saturday. The NAM and ECMWF have
similar ideas, but are slightly further south with the low track
(e.g., 978mb over Long Island Sound in the 00Z ECMWF soln).
This evolution induces very strong 850-700mb frontogenesis
forcing across the North Country during the daylight hours
Friday. Strong dynamic cooling allows most areas to switch back
to snow across nrn NY into the Chamaplin Valley Friday morning,
and then the snow/mix line will gradually work ewd across
central/ern VT as the low deepens to our east. Frontogenesis
forcing is pronounced and collated with weak static stability.
Combined with favorable straight hodographs and a col point near
5kft, should lead to quasi- stationary mesoscale banding
somewhere across our forecast area for a few hrs around mid-day
Friday. Given the moisture laden nature of this system,
ingredients are in place for mesoscale banding producing 1-2"/hr
snowfall rates mid-day hours Friday. We'll just have to see
where the strongest baroclinicity sets up, but have highlighted
the 1-2"/hr snowfall rates in the Winter Storm Watch discussion.
As the surface low departs, should also see some areas of
blowing snow as north winds increase to 15-25 mph with gusts to
30 mph late Friday afternoon. Temperatures should fall through
the 20s Friday afternoon as low-level CAA increases.

Storm Total Snowfall by Friday evening should range from 4-8"
across Rutland/Windsor counties (where mixed pcpn will be of
longer duration), and 8-13" across nrn VT and nrn NY. As
mesoscale banding details become more clear in the next 24
hours or so, the locations favorable for the heaviest snowfall
should become more evident. See weather.gov/btv/winter for
latest graphical snowfall depiction and corresponding
probabilistic information.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
As of 224 AM EST Wednesday...Snowfall will continue Friday night but
will begin to taper off as the frontogenetic forcing and moisture
begins to slide eastward. This should allow for snowfall to end at
most locations by midnight with strong cold air advection allowing
for continued upslope snow showers along the western slopes of the
Green and Adirondack Mountains through Saturday morning. An
additional 1-2 inches looks likely Friday night with 2-4 possible
along the western slopes. Temperatures will also plummet Friday
night behind a strong arctic cold front with overnight lows dropping
into the single digits above and below zero. We will continue to
hold onto a decent pressure gradient overnight as well as mostly
cloudy skies. This will inhibit us from seeing temperatures plummet
as far as they would under a good radiational cooling night. With
the lingering winds Friday night, it is possible we could see wind
chills range from -5 to -20 degrees toward sunrise.

Saturday will be the coldest day of the forecast as high
temperatures struggle to warm into the lower teens to lower 20s as a
cold arctic high pressure system settles into the North Country. The
good news, however, is that we should see some sunshine on Saturday
with an abundant amount of drier air filtering into the region from
the north. On the other hand, this will lead to another cold night on
Saturday as the gradient flow will weaken significantly with the
high pressure system cresting overhead. Low temps Saturday night
into Sunday will likely be around 5 degrees cooler with portions of
northeastern Vermont likely to drop into the double digits below
zero.

On Sunday, our flow aloft will switch to the west while our low
level flow will switch to the southwest. This will allow us to
advect in warmer air and moisture back into the North Country. That
one day on sunshine on Saturday is all you'll get with abundant
cloud cover expected to redevelop on Sunday. With the flow aloft
becoming more zonal, we will see several low amplitude shortwaves
track through New England through late this weekend into the middle
of next week. This will lead to an active pattern where chances of
snow and rain will be possible but no major systems look imminent
through the Wednesday timeframe. Temperatures will moderate from
Sunday onwards with overnight lows and afternoon highs several
degrees above normal.

.AVIATION /18Z WEDNESDAY THROUGH MONDAY/...

storm system. Winds will be from the north and northwest at 5
to 12 knots today but will shift to the southwest and weaken
this evening. Snowfall will move into the region between 09Z
and 11Z with IFR visibilities expected at all terminals as a
burst of light to moderate snow impacts the region. Snow to
continue across the area during the 12-18z timeframe, with some
mixed precipitation expected later in the evening.
