Regional Weather Summary
National Weather Service State College PA
612 PM EST Mon Nov 10 2025
A deep upper level trough associated with very cold air aloft will
push east across Pennsylvania tonight. In its wake, the northwest
flow will become well-aligned through an extensive vertical layer
late tonight and much of Tuesday, creating heavy lake effect snow
in excess of 8 inches across Warren county. Multiple, slowly
meandering snow bands will bring a few to several inches of snow
accumulation further inland across the Northwest Mountains and
ridge tops of the Laurel Highlands to the west of route 219.
The cold air crossing the relatively warm waters of the Great
Lakes will push moisture well inland, leading to flurries and
scattered snow showers across the Central Ridge and Valley Region
of the state with light snow accumulations of a coating to one-
half inch possible as far southeast as the Interstate 99 and Route
220 corridors. Partly cloudy skies with just some scattered
flurries will occur across the Susquehanna Valley.
Lows at sunrise Tuesday morning will range from the upper teens
and low 20s across the Allegheny Plateau to around 30 degrees in
the city of Philadelphia, with wind chills ranging from the single
digits across the Allegheny Plateau to the low 20s in the
immediate Philadelphia area. Temperatures will remain chilly into
Tuesday afternoon, with highs only recovering to the 30s to mid
40s statewide.
Wind gusts will increase to the 30 to 40 mph range for the
daylight hours Tuesday.
Tuesday will be the coldest day of the week, with temperatures
gradually moderating for the second half of the week.

Area Forecast Discussion
National Weather Service State College PA
647 PM EST Mon Nov 10 2025
.SYNOPSIS...
* Wintry precipitation will continue to fall over the north and
western highlands as temperatures fall on the back side of the
departing surface low.
* Lake-effect and upslope snow showers will be heaviest Mon
night into Tues, along with the coldest temperatures of the
season thus far.
* Temperatures should begin to moderate by late week.

.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
Snow struggling to stick almost anywhere it is snowing. The
cellular showers are so small and the sun is still making it
thru in spots - making it tough to stick. Webcams across the NW
this aftn show almost no accum in many places SE of Kane. Even
in the Laurels, only very! brief forays below 2sm visby have
been occurring. This is in line with all the forecasts.
What will change to make it stick is that the sun will set, the
sfc temps will drop: grass first, then bridge decks then,
lastly, roads. The flow will also start to back and a better
Huron connection will fatten up a big band or a few heavier
bands and these will last all night and morning. The band
orientation will be mainly NW-SE thru the night. As is usual, it
will be tough to get more than a dusting to the SE of the
Allegheny Front. However, some will make snow into Happy Valley
and the lower West Branch valley. The accumulations will be
minimal, and have only mentioned less than an inch in general
there. Other than that tweak, the forecast snow amounts for the
overnight still look good.
Planning no changes to the WWAs - but did strongly consider
extending the warning and advys into the late aftn or even into
the early evening. Many times, I think, forecasters tend to try
to end the lake effect a little too early. But, we`ll mention
that possibility onto the next shifts.
The currently wet roads will start to freeze up if not treated,
and slick spots will be likely. It is the first snow of the
season for many people. Allow extra time for travel and taking
care of the shoveling, etc. and not rush to get places.
&&
.SHORT TERM /6 AM TUESDAY MORNING THROUGH TUESDAY NIGHT/...
Our lastest thinking is almost the same as the previous
reasonings. But, one difference is that the snow bands may stick
around longer into the aftn - and maybe early evening. While the
worst/heaviest of the snow will be during the morning, some
bands could linger. After collaboration with neighbors, we
decided to not extend (in time) the warning and advisories in
the north. Will advise the next shifts on this possible change
to watch for if trends continue. Otherwise, te backing flow will
gradually take away/break up our Huron connection, and break the
bigger band(s) into smaller ones, and lay them out more west to
east (vs NW-SE that will prevail tonight and early AM). Temps
do rise again, but stay cold enough for accums on the grassy
surfaces/dead leaves/trees during the day. Roads will have a
chance to warm up and make it more difficult for it to stick
there. Maxes will be just above freezing in most places which
will receive snow, and upper 30s to lower 40s SE of the
Allegheny Front. Just the tops of the highest hills of the NW
and Laurels will stay below freezing.
The lake effect machine will be completely out of our hair in
the late aftn/early evening. But, a quick-moving upper level
system will direct a patch of light precip across MI and nrn OH
into far nrn PA and wrn NY Tuesday night. Any accums will be
<1" overnight. So, the break in snow may not last more than
12hrs, if even 6 hours along the NY border.
&&
.LONG TERM /WEDNESDAY THROUGH MONDAY/...
Upper-level troughing will remain in place through the end of
the week, keeping the chance for rain and snow showers in the
forecast each day through Friday, especially over northwest PA.
A tight pressure gradient will allow for winds gusts in the 30
to 35 mph range Wednesday, with some guidance suggesting the
potential for gusts over the Laurel Highlands to approach 40 to
45 mph.
The December-like cold airmass is forecast to retreat later in
the week, with temperatures returning closer to seasonal
averages. High pressure looks build in from the southwest Friday
into early Sunday, which should keep us mainly dry into the
beginning of the weekend.
Another northern stream upper shortwave traversing the Northern
Plains will reach the Great Lakes early in the weekend and
support a low pressure/frontal system that will move across PA
Sunday into next Monday. At this point, this system appears to
be not as strong or as cold as our current one, so any precip
looks to be mainly in the form of rain/rain showers.
&&
.AVIATION /00Z TUESDAY THROUGH SATURDAY/...
A relative minimum in snow shower coverage is expected over the
next few hours. Low-level flow will gain more of a westerly
component overnight and will direct heavy lake effect snow bands
into Central PA. This will also allow for more upslope snow
showers at JST and AOO. Expect IFR/LIFR conditions at BFD for
much of the night, while JST likely remains MVFR with brief
periods of IFR possible. Most guidance indicates the potential
for some of the heavier snowbands to make it all the way down to
UNV and IPT by early morning. MDT and LNS will likely remain
VFR through the TAF period, though there is around a 15 percent
chance of a few snow showers making it that far southeast. Snow
lifts north of JST and AOO by mid-morning, but snow will
continue at BFD into the afternoon.
Strong winds a few thousand feet above the surface should mix
down fairly easily tonight and during the day on Tuesday, with
gusts of 25 to 35 knots expected at all TAF sites. VFR
conditions may briefly return area-wide late in the TAF period
with just a few lingering snow showers near BFD. Snow chances
increase again Tuesday night into Wednesday morning.
Outlook...
Wed-Thu...Rain and snow showers over northwest PA along with
gusty winds.
Fri...Improvement expected, with winds diminishing and
lingering -SHSN across NW PA diminishing as well.
Sat...Dry, generally VFR.
