Area Forecast Discussion
National Weather Service Burlington VT
1252 AM EST Fri Jan 12 2024
.SYNOPSIS...
Snow showers across the region tapers off this evening. After a
dry day on Friday, our next winter storm arrives Friday evening
into Saturday. Expect strong to locally damaging winds along
with widespread accumulating snowfall, mixing with rain in the
valleys. Gusty winds continue for Saint Lawrence valley along
with lake effect snow showers on Sunday. Relatively quiet and
seasonable conditions return for the start of next week before
another potential system arrives mid week.
&&
.NEAR TERM /THROUGH SATURDAY/...
As of 943 PM EST Thursday...Another small adjustment to the
forecast to keep light snow showers/flurries going for a few
more hours this evening/early tonight before ending overnight.
Otherwise the forecast remains in solid shape. Have a great
night!
Excerpts from prior discussion...
Upper level ridging builds in on Friday along with surface high
pressure, so sunshine returns in time for end of the work week.
It will be quite a pleasant day so it might be a good
opportunity to finish clean up from the previous system and
prepare for the next one that arrives later in the evening.
Another day of seasonable daytime highs in the mid 20s to low
30s is expected, except mid to upper 30s across far southern
Vermont.
&&
.SHORT TERM /SATURDAY NIGHT/...
As of 259 PM EST Thursday...
* Our next winter storm arrives late Friday into Saturday,
bringing strong to damaging winds along with widespread
accumulating snowfall.
* Best chance for damaging winds will be along the western
slopes of the Green Mountains, with 70 mph gusts possible.
Given that we were impacted by a high wind event just 72 hours
prior, the threshold for property and vegetation damages may
be lower with this event.
* A burst of heavy, wet snow with snowfall rates exceeding 1
inch per hour is likely overnight Friday. Best chance for over
6 inches of snowfall is across northern Adirondacks.
Global ensemble guidance (ECMWF, GFS and GEM) has all come into
rather good consensus of the evolution of this upcoming winter
storm. Overall, ensemble members show good clustering of the
primary low tracking northeastward from the Ark-La-Tex region
towards St Louis on Friday morning, eventually deepening to sub-
980mb over southern Wisconsin. By Friday evening, a secondary
area of low pressure forms off the Georgia/South Carolina coast,
and tracks up the Atlantic seaboard near the 70W/40N benchmark
on Saturday morning. In terms of a generic sequence of events,
first, there would be a front-end thump of snow, mixed with
sleet at times as the best frontogenetic forcing comes through
Friday evening into the overnight hours. So the good news is
that road impacts should be minimized since this is after the
Friday evening commute. Forecast wise, temperatures should fall
off initially after sundown Friday evening into the first half
of the overnight hours. BUt then as warm air advection
strengthens, temperatures will stabilize and then become non-
diurnal during the overnight hours. Of course, as moderate to
heavy precipitation rates move in, i.e. front end thump,
dynamical cooling from wet bulbing will lead to local
temperature fluctuations that would be impossible to be overly
precise at this time frame. There is high confidence that it
will start off as snow at the get go, with a non-zero but
negligible brief period of drizzle at the very onset. With the
mid week system, many valley locations observe a heavy wintry
mix of snow and sleet with the impressive frontogenetic band. So
given a very similar synoptic setup and a similar air mass,
there is little reason to think that sleet would not mix in. But
there would be a period of difficult travel, particularly
during the evening to first half of overnight hours with 1 to
1.5 inch per hour of accumulation expected. Right now, the best
chance for over 6 inches of snowfall would be across western
Essex and Clinton counties in NY, where Winter Storm Watches
have been hoisted. Expect 1-4 inches generally elsewhere across
northern NY, as well as east of the Greens. For the immediate
Champlain valley, mixing issues should generally keep
accumulations to the 0.5 to 3 inches range. Given the strong
southeast winds, the east- facing slopes of the Green Mountains
could see locally higher amounts of 3-7 inches possible with
orographic enhancement. Finally, there could be a glaze up to a
few hundredths of an inch of ice accretion across the favored
areas, including portions of the St Lawrence valley and east
slopes of the Greens. But the ice accretion would be rather low
in the priority ranking of the hazard threats.
This would be followed by a period of gusty to locally
strong to damaging winds with the intense southeast flow. Most
vulnerable areas would be along the western slopes of the
Greens, where a High Wind Watch has already been hoisted. With
this forecast package, we are expanding the High Wind Watches to
Rutland, Addison county, Orleans, Lamoille and eastern Franklin
county. For Rutland, the wind direction is due east, which
unfortunately is favorable for higher end downsloping impacts.
Something to consider is that some infrastructure and vegetation
has been compromised from the last event just 72 hours prior.
Another consideration is that the strongest winds aloft look to
coincide with lower precipitation rates, which could allow for
better mixing down to the surface. With the previous mid week
system, it was a relatively narrow window when Burlington gusted
to 69 mph, when the precipitation lightened up. So despite the
850mb jet being slightly weaker than the mid week system (70-75
kt vs. 80-85 kt), slightly better mixing and more compromised
infrastructure could result in just as bad or even slightly
worse impacts.
For snow lovers, the development of the secondary coastal low is
timely as it caps the magnitude of warm air advection. It also
greatly diminishes the hydrologic threat, since rain and melting of
snowpack would be minimized. It does have the potential of
entraining low level cold air, so typical spots like the St Lawrence
valley and sheltered locations east of the Greens need to watch for
freezing drizzle or rain for a time on Saturday. Another potential
complicating factor is the development of a narrow area of secondary
low right over the Champlain valley, as depicted by the mesoscale
guidance just coming into range for this system. This looks
reasonable as when there is such an intense primary low pressure
system, a localized area of secondary low develops. So after the
front end thump, an area of steady precipitation could continue into
the mid morning hours before the dry slot moves in. Given that this
is a progressive system, the storm will be pulling away into the
Gulf of Maine by Saturday afternoon with showers increasingly
confined to the terrain. However, there is a risk of strong
southwest winds developing across the St Lawrence valley later
Saturday. As the aforementioned primary low pressure system
continues to deepen and track into southwest Quebec, there is
potentially the development of a sting jet. Along with lake
effect snow showers off Lake Ontario, there could be areas of
blowing snow and reduced visibilities across St Lawrence county
on Sunday. Confidence in the timing and its evolution is quite
low at this time, so stay tuned for more details.
&&
.LONG TERM /SUNDAY THROUGH THURSDAY/...
As of 259 PM EST Thursday...Our active pattern looks to continue for
the long term as temps finally trend toward normal by next week.
Departing sub-980mb low pres on Sunday wl produce areas of brisk
winds and lake effect snow, especially northern NY. Quick
investigation of soundings at MSS show deep layer mixing to 800mb,
under moderately strong llvl caa. This scenario, combined with
enhanced channeling on sw to ne orientation of 850mb jet of 45 to 60
knots, supports localized gusts to wind advisory levels. Thinking
gusts 40 to 50 mph is likely on Sunday acrs the SLV and portions of
the northern Dacks. Guidance continues to indicate secondary s/w
energy and associated boundary crossing our cwa btwn 18z Sunday and
03z Monday. This energy/forcing and additional moisture from the
Great Lakes, wl be enough to produce a period of snow showers acrs
most of the area, with localized enhancement in the persistent lake
effect bands. Furthermore, as progged 850mb temps drop btwn -12C and
-15C late Sunday into Monday, lake instability parameters increase,
resulting in conditions favorable for lake effect snow showers.
Greatest areas of impact look to be acrs southern St. Lawrence
County into parts of the western Dacks and northern Greens, where
some snow accumulation is likely. This combined with brisk winds, wl
create areas of poor traveling conditions on Sunday into Monday.
Monday is relatively quiet with some lingering mtn snow showers and
leftover lake effect moisture, but impacts are minimal. Temps should
be near seasonable levels on Monday in the upper teens to upper 20s.
Clouds and winds prevent temps from reaching normal overnight lows
on Sunday night and monday night.
For midweek, the potential for another system is being watched
closely. The latest 12z deterministic runs of the GFS/UKMET/CMC and
NAVGEM all show a potential coastal system, while the 12z ECMWF has
backed off on that idea. Large scale synoptic pattern generally
shows deep full latitude mid/upper lvl trof developing acrs the
eastern CONUS, while numerous s/w's are embedded within the trof.
Also, it should be noted given the contrast of airmasses acrs the
Eastern Seaboard wl be increasing, helping to enhance large scale
fgen. It comes down to timing of northern/southern stream energy and
when they phase, if another system wl impact our cwa. For now, just
stay tuned and monitor latest forecasts. Temps will trend at or
below normal by the end of the week.

Through 06Z Saturday...Primarily MVFR conditions, with some
localized IFR conditions, across all terminals tonight as
scattered to numerous snow showers continue across the region.
These snow showers and associated IFR visibilities, should
largely taper off over the next several hours, generally by 09Z.

towards the end of the forecast period, with precipitation
gradually spreading across northern New York into Vermont. Winds
will be northwesterly for the first portion of the TAF period,
becoming more northeasterly with the VFR conditions and then
stronger east/southeasterly winds with the approaching system,
with strong gusts possible, although the strongest winds are
currently outside of the forecast timeframe.

Hazardous weather is not expected at this time. .DAYS TWO THROUGH SEVEN...Friday through Wednesday. Our next winter storm arrives late Friday into Saturday, bringing strong to locally damaging winds along with widespread accumulating snowfall. Best chance for damaging winds will be along the western slopes of the Green Mountains, with 70 mph gusts possible. Given that the region was impacted by a high wind event just 72 hours prior, the threshold for property and vegetation damages may be lower with this event. In addition, a burst of heavy, wet snow with snowfall rates exceeding 1 inch per hour is likely for a period overnight Friday. Valley locations will mix with and change over to rain by Saturday morning. Best chance for over 6 inches of snowfall is across northern Adirondacks. .SPOTTER INFORMATION STATEMENT...
