Area Forecast Discussion
National Weather Service Burlington VT
622 AM EST Mon Jan 25 2021
.SYNOPSIS...
Temperatures will begin to moderate today and conditions will be
dry with high pressure passing overhead. A low pressure system
moving through New York will bring some light snow to the area
late Tuesday through midday Wednesday. Some snow showers will
linger over the higher terrain into Thursday. Temperatures will
drop to below seasonable norms Friday and Saturday.
&&
.NEAR TERM /THROUGH TUESDAY/...
As of 550 AM EST Monday...Forecast in good shape going forward
with no major changes needed. Low clouds are spreading over
northern New York as expected, which have allowed temperatures
to climb over the northern Adirondacks and Saint Lawrence Valley
after hitting impressive early morning lows. Meanwhile further
east, clear skies over the Champlain Valley and much of Vermont
have allowed temperatures to fall to near zero shortly before
sunrise. Previous discussion follows...
Today and tonight will be relatively quiet on the weather front
with high pressure slowly moving northeastward over our
forecast area. Temperatures will begin to moderate starting
today as the high shifts to eastward. Highs today will be in the
upper teens to mid 20s...a good 10 degrees above yesterday's
highs for much of the area. For tonight, still expecting some
mid and high clouds to spread over the area that will limit
diurnal heat loss. In addition, forecast soundings are
indicating some of the higher terrain will have low clouds
persisting tonight. Thus, despite high pressure over the region,
thinking overnight lows will generally stay above zero, and up
to the low teens in the valleys.
Temperatures will continue to moderate Tuesday as a low pressure
system tracks to western NY, sending a warm front towards our
forecast area. Pretty much all of the model guidance has taken a
northward shift in this low pressure system that was previously
expected to stay to our south. Thus, Tuesday/Tuesday night forecast
has changed for the North Country, and snow lovers will embrace the
change since this shift does bring some snow (albeit relatively
light) into the area. Snow will spread over northern NY late Tuesday
afternoon, moving north and eastward into the evening hours. See
Short Term Discussion for more details on this snow event.
&&
.SHORT TERM /TUESDAY NIGHT THROUGH WEDNESDAY/...
As of 235 AM EST Monday...A period of accumulating snows
appears likely Tuesday night into Wednesday morning as weakening
low pressure lifts into the region. Warm advection processes
and modest isentropic lift through the mid- levels (around 290K)
will will be the main players here, with strongest forcing
setting up across southern Adirondacks into Essex County, NY and
across our southern VT counties. That said, the primary
dendritic snow growth zone generally lies above the area of best
lift, boosting confidence that this will largely be a light
snowfall event. I leaned heavily toward a model-blended solution
in regard to QPF, downplaying this morning's GFS contribution
with it's typically biased higher amounts under weak/modest WAA
events. Steadier light snows then become more amorphous and
lessen in overall coverage into Wednesday afternoon as warm
thermal advective processes wane. Early snowfall total estimates
from late Tuesday afternoon through noon Wednesday or so will
average generally in the 1-3 inch range, with slightly higher
amounts from 2-5 inches across Essex County, NY and
Windsor/Rutland counties in VT. With an abundance of clouds and
light near-surface winds temperatures will show a smaller than
normal diurnal range through this period, averaging generally
from the mid teens to lower 20s Tuesday night, and in the 20s on
Wednesday.
&&
.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
As of 235 AM EST Monday...Lingering light snow and/or snow
showers continue to wane into Wednesday night/Thursday, with
best coverage across the eastern higher terrain where some minor
additional accumulations will be possible. Forcing is quite
weak however so nothing too notable by late January standards.
The primary feature during the late week time frame will be a
fairly impressive arctic shortwave trough forecast to dive
southeast through the area Thursday evening into Friday morning
which will usher in a much colder airmass for Friday into
Saturday. With the arrival of this feature expected at night,
the threat of more organized squalls appears rather low at this
point, but at least some lower-end PoPs will be maintained to
account for the cold frontal passage. Highs on Thursday near
seasonal values in the upper teens to mid 20s in nrn NY and
through the 20s in VT, then considerably colder Fri/Sat (single
digits and teens).
Looking further out there is some indication that another round of
accumulating snows will occur by Sunday night or perhaps on Monday
as temperatures moderate ahead of a rather complex system advancing
east from the Great Lakes.
&&
.AVIATION /11Z MONDAY THROUGH FRIDAY/...
Through 12Z Tuesday...Mainly VFR conditions expected through 06Z
with light and variable winds. The only exception will be KSLK,
where some MVFR ceilings are currently being reported and are
expected to remain through 23Z before lifting some to VFR
levels. Otherwise, will see some bkn/ovc ceilings between 2000
and 3000 ft spread over much of the area between 06Z and 12Z.
Outlook...
Tuesday: VFR. Chance SN.
Tuesday Night: Mainly MVFR, with areas VFR possible. Chance SN.
Wednesday: MVFR. Chance SN.
Wednesday Night: Mainly MVFR, with local IFR possible. Chance
SHSN.
Thursday: Mainly MVFR, with local VFR possible. Slight chance
