Regional Weather Summary
National Weather Service State College PA
446 PM EST Wed Dec 31 2025
An arctic front will be driving tonight bringing gusty winds and
winter weather driving conditions. Along and just ahead of this
arctic front, one or two extensive bands of heavy snow squalls
will bring anywhere from a coating to 2 inches of snow in just 30
minutes, creating the potential for brief whiteout conditions in
heavy falling and blowing snow with wind gusts of 35 to 45 mph.
The front with its bands of squalls will probably be near Erie
just after 8PM EST, Pittsburgh in the late evening close to
midnight, and getting close to Scranton, Harrisburg, and
Chambersburg right around 1 to 2AM time frame. Midnight
temperatures will range from the mid teens in the northwest to
around the freezing mark in Philadelphia, Harrisburg and
Chambersburg.
The wind chills will be down in the single digits over the
northwest at that time, and teens and 20s elsewhere. Plan ahead
for the blustery weather if you plan to be on the roads, even for
a short time, as we turn the page to 2026.
Very cold temperatures, plenty of clouds and flurries, with
significant lake effect snow continuing across the Northwest
Mountains will be the Main Weather story for the first day of
2026. Thursday`s highs will be between 15 and 20 degrees across
the Northern and Western Mountains, with mid to upper 20s
throughout the Susquehanna Valley. The high temps will be
anywhere from 11 to 18 degrees below normal for the first of
January.

Area Forecast Discussion
National Weather Service State College PA
430 PM EST Wed Dec 31 2025
.SYNOPSIS...
* Snow and embedded squalls will develop tonight across parts of
central PA, associated with a strong cold front
* Areas of lake enhanced and upslope snow will persist into New
Year`s Day, along with very cold wind chills
* Moderating temperatures are expected over the weekend and into
next week
&&
.NEAR TERM /THROUGH THURSDAY/...
As of mid-afternoon, we`re in a relative lull across central and
northwest PA, as backing flow ahead of our next incoming
disturbance shunts the main Lake Erie band well north, and also
effectively cuts off Lake Erie moisture to help feed lake-
enhanced/upslope snow showers into the Alleghenies.
However, the break won`t last long, as a digging short-wave over
the northern lakes and an associated surface arctic boundary is
waiting in the wings. Model guidance depicts increased westerly
flow in the 925-850 mb layer this evening as these systems
approach, which will enhance the upslope component into the
Laurel Highlands, in addition to the general synoptic lift at
play from the upper-level wave. This all points to a period of
moderate-heavy snow tonight in the Laurel Highlands, with HREF
guidance showing increased probabilities for 1"/hour rates
between about 02z and 09z. Thus, our current Winter Storm
Warning in Somerset county and high-end Advisory in Cambria
county appear to be in good shape.
The other issue later tonight will be snow squall potential
along the surface boundary. Good convergence along this front,
unstable conditions in the upper part of the boundary layer, and
decent forcing aloft point to the potential for robust linear
development. We`ll continue to message this threat and closely
monitor conditions tonight, especially considering NYE
celebrations concurrent with likely snow squall development.
NW flow lake-effect bands are also expected to kick in overnight
behind the front. This scenario is well handled by our Warning
in Warren and McKean counties, as well as adjacent Advisories
for Potter, Elk, Cameron, and Clearfield counties.
On New Year`s Day, strong cold advection and moisture off Lake
Erie will continue the lake snow bands at least through the
midday hours, with a gradual reduction likely in the afternoon,
as the capping inversion starts to come down.
As for the snow in the Laurels is concerned, although NW flow
upslope will continue to produce general snow showers, the
heaviest snow should be over, as synoptic-scale upglide will be
significantly less by then.
In general, it will be a cold and windy start to 2026, with -/+
single digit wind chills anticipated for most of the area.
&&
.SHORT TERM /THURSDAY NIGHT THROUGH FRIDAY/...
Cold NW flow will continue this period, with brisk conditions
and biting wind chills foreseen area-wide.
Although most of central PA will either be dry or just
experience a few flurries, lingering lake snow bands in the
northwest snow belt areas, as well as upslope snow showers in
the Laurels, could bring small additional accumulations.
&&
.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
In general, a break from the persistent cold/below normal
temperatures is foreseen for central and northwest PA, as
upper-level heights relax, and a more zonal flow regime settles
in.
Fast moving disturbances could bring occasional periods of light
rain or snow, but overall, no major storms are anticipated at
this time.
&&
.AVIATION /21Z WEDNESDAY THROUGH MONDAY/...
Late afternoon update.
Adjusted TAFS some. Some spots with low CIGS, but not much
in the way of snow showers for a brief time, much of the hazy
look is not snow, but just moisture, fog and smoke.
Earlier discussion below.
Lake effect SHSN have lifted away from the western highlands,
but a patch of very light but nearly-constant snow is falling at
18Z. This light snow should diminish/end for a short time, but
will be replaced rather quickly by another, larger patch of
more-constant, light snow which should move into the west before
23Z. That patch is being forced by a significant short wave
trough aloft. Expect conditions to deteriorate again as that
snow becomes widespread. While this is going on, the VFR over
the eastern terminals will continue.
Things get worse for travel this evening and tonight. The trough
aloft will be undercut and the snow enhanced by a very sharp and
active arctic front. The front will force at least one line of
snow squalls. Some model guidance has the squall as one,
continuous/coherent line/band right along the front. Meanwhile,
some guidance has multiple/broken bands. Each of these scenarios
would still push squalls into the southern terminals. However,
we do expect the strength of the squalls to decrease as the
front passes an RVL-SEG-AOO line. Some re-intensification of
the squalls is still possible (30%) in the Lower Susq (MDT/LNS),
though, as their slightly warmer temperatures there as the
front arrives could cause some CAPE/instability. But, guidance
probability of IFR cigs/visby drops to <20% after the front
pushes thru IPT-UNV-JST. Gusty WNW wind will accompany the
squall(s) with the highest gusts over the Laurel Highlands.
Timing of the worst of the squalls (or single squall) is
looking a little slower than previous guidance. We are now well
within the CAM/HREF`s time-horizon of best performance.
Encouraging is that many of them have started to agree on a
consensus of timing. Therefore, with some increased confidence
in the time of arrival, we have adjusted the times when LIFR is
possible at each terminal back/slower 1 to 3 hours from what was
mentioned in the 12Z package.
Post-FROPA, the sfc wind will go westerly W, and may even
decrease a few KTs on the whole with less gustiness. But, the
arrival of daylight and mixing will get them gusty again. but
still be gusty. The SHSN over the Laurels (JST) will be only
widely sct after 12Z. The classic lake effect wind field will
keep BFD under the threat (>60% chc) of IFR all Thurs and even
Thursday night - even though SHSN will taper off in BFD aft 00Z
Fri.
Outlook...
Fri...VFR S & E. MVFR cigs with a chance of a snow shower at
BFD and perhaps JST.
Sat...Still a chance of a snow shower early at BFD, then VFR.
Sun...Mainly VFR.
Mon...Clipper system with sct/numerous SHSN W w/IFR poss.
Mainly MVFR E.
