Area Forecast Discussion
National Weather Service State College PA
217 AM EST Sun Jan 14 2024

.SYNOPSIS...
Winter is poised to make a big comeback through mid January as
arctic air invades the area over the next several days. Snow
showers and blustery winds will continue through tonight with
additional light snow accumulation over the Allegheny Mountains.
Snow squalls are possible Sunday morning as arctic air blasts
into central PA. A widespread light snow accumulation is
possible late Monday night into Tuesday as a storm tracks off
the East Coast. Subzero wind chills are forecast over the
Alleghenies Sunday night into early Monday morning and again
Tuesday night into early Wednesday morning. Below normal
temperatures are forecast into next weekend. Welcome back
winter.

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...
Gradually diminishing winds are expected overnight, as deep
surface low over Southern Quebec begins to pull away from the
region. A relatively shallow layer of moisture trapped beneath a
subsidence inversion is producing stratocu over all but
Southeast PA late this evening, with occasional light
snow/flurries where the flow is forced to ascend the
Appalachians. Model qpf indicates any additional accumulation
through 6 AM will be less than an inch and confined to the
Allegheny Plateau.

An active southwest breeze will keep temperatures from falling
too far from 01Z readings with low expected to range from
around 20F over the NW Mtns, to around 30F over the Lower Susq
Valley.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH TUESDAY/...
The focus for early Sunday will be on the threat of snow
squalls accompanying the passage of an arctic cold front. Low
level convergence along the front, combined with steep lower
tropospheric lapse rates and some cape, argues for a band of
snow squalls to accompany the fropa as it traverses Central PA
between 12Z-17Z. The majority of convection-allowing guidance
targets the southeast half of the forecast area for the greatest
threat of squalls. The threat is especially high over the Lower
Susq Valley, where breaks of sun and temps rising above
freezing could set the stage for a possible flash freeze if
squalls materialize as expected. We will continue to strongly
message the potential for dangerous squalls across all of our
dissemination platforms.

A winter weather advisory remains up for the Laurel Highlands
in coordination with LWX/PBZ through midday Sunday given
combination of 2-3" of upslope snowfall and gusty winds
35-40mph.

Strong cold advection will result in falling temperatures
behind the front during the late morning and afteroon, with
readings falling to the teens and 20s by Sunday evening. Deep
mixing, combined with the passage of of a decent isallobaric
wind couplet and subsidence forced by differential anticyclonic
vorticity advection will will produce a bout of strong/gusty
winds behind the front Sunday. Latest Bufkit soundings support
fairly widespread peak gusts in the 35-40kt range, resulting in
wind chills falling below zero in the afternoon across the
Allegheny Plateau.

Surface ridging is progged to build into the region Sunday
night, bringing fair weather with diminishing winds. A
southwesterly flow in the boundary layer will keep lake effect
snow well north of the border. See no reason to deviate from NBM
min temps Sunday night, which range from the single digits over
the Allegheny Plateau, to the teens in further east. A
diminishing wind should keep apparent temps above wind chill
criteria, but it will definitely be the coldest night of the
winter so far.

Generally fair and cold conditions are expected Monday under
surface ridging. Increasing fgen forcing is noted in the model
data across Central PA late Monday night associated with
a jet streak circulation linked to an approaching upper trough.
Surface ridging and dry air may limit the chance of precip over
Northern PA. However, ensemble plumes support an increasing
chance for a period of light snow late Monday night into
Tuesday AM over the southern counties.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
The big story for the long term looks to be a extended stretch
of below average temperatures and the coldest weather we've
seen so far this winter. Medium range guidance indicates a
negative NAO pattern will persist through next week, deflecting
the polar vortex southward with below normal heights across the
northeast CONUS. The coldest temperatures look to occur on
Tuesday night and Wednesday, as the upper trough axis pivots
over PA. Relatively light winds will likely keep wind chills
just above advisory criteria over the NW Mtns.

Dry weather is anticipated Tuesday PM through Thursday AM, as
surface ridging builds in from the Ohio Valley and a southwest
flow directs lake effect snow to the north of PA. A deepening
upstream trough over the Grt Lks is progged by all guidance to
push into PA at the end of next week, delivering a reinforcing
shot of cold air. Current EPS/GEFS suggest a relatively weak
surface low associated with the trough will track over or just
south of PA Friday, accompanied by a period of light snow Friday and
followed by blustery and cold conditions next weekend, with
lake effect snow possible over the W Mtns. However, a few
members develop the low faster as it passes south of PA,
indicating an outside chance of a more significant snowfall
Friday.

&&

.AVIATION /07Z SUNDAY THROUGH THURSDAY/...
Light snow across the western highlands will continue to bring
periods of IFR vsby through much of the night for BFD. By
Sunday morning, an arctic front will begin to move through
Central Pennsylvania with snow squalls expected to develop along
the frontal boundary. Model consensus indicates that the
squalls will impact western sites (BFD, JST) between 11-15Z,
central sites (AOO, UNV, IPT) between 13-16Z, and eastern sites
(MDT and LNS) by 15-18Z. The squalls will lead to sudden drops
in visibility, likely below 1/2 mile in spots, along with the
potential for wind gusts in excess of 40 kts. Behind the arctic
front, MVFR cigs may continue across BFD and JST for a few
hours, but after 21z VFR conditions are expected to prevail
areawide in the dry, Arctic airmass.

Outlook...

Mon...MVFR cigs possible west, VFR east. Snow developing from
south to north Mon Night.

Tue...Periods of snow, mainly early.

Wed-Thurs...A few snow showers across the NW, especially
Thursday. VFR elsewhere.
