Area Forecast Discussion
National Weather Service State College PA
139 PM EST Sun Nov 16 2025

.SYNOPSIS...
* Windy and colder with lake effect snow bands lasting into
  Monday; snowy road conditions/hazardous travel possible in
  blowing/drifting snow
* Light rain/snow possible Tuesday followed by a slightly milder
  trend through the middle of next week

&&

.NEAR TERM /THROUGH TONIGHT/...
Widespread rain and snow showers will continue to move across
Central PA through the rest of the day. Most of the precip this
morning fell as rain outside of the higher elevations, but a
slow transition to snow is taking place this afternoon as colder
air works its way in. Expect all of the precip to change over
to snow by sunset. The snow will also take on more of the
typical banded lake effect appearance as opposed to the more
cellular nature being observed now with the loss of daytime
heating, resulting in a greater likelihood of accumulating
snowfall over northwest PA. Total snowfall of 5 to 8 inches is
expected in the area covered by the Lake Effect Snow Warning,
while areas covered by the Winter Weather Advisory should see
snowfall in the 2 to 5 inch range.

High res guidance continues to show the potential for some of
these bands/squalls to reach pretty far inland overnight,
potentially even extending into the Lower Susquehanna Valley.
These bands may cause rapid changes in visibility and quick
accumulations on roadways, leading to hazardous travel
conditions.

The other concern today is strong winds. Gusts of 40 to 50 mph
will be likely through the rest of the afternoon along with a
few gusts as high as 55 mph as we continue to tap into 50 knot
winds at the top of the mixed layer. These winds could blow
around any unsecured objects and may result in scattered power
outages. Wind stay strong overnight, with gusts of 30 to 40 mph
likely. A Wind Advisory remains in effect for the entire CWA
through midnight.

&&

.SHORT TERM /MONDAY/...
Snow showers gradually decrease in coverage through the day on
Monday as inversion heights begin to fall, though it likely
takes most of the day for snow to come to an end across the
northern tier. High temperatures will range from the low 30s to
the mid 40s. Winds will remain gusty, though likely not as
strong as on Sunday, with gusts in the 30 to 40 mph range.

&&

.LONG TERM /MONDAY NIGHT THROUGH SATURDAY/...
Snow showers and gusty winds taper off Monday night as high
pressure briefly builds into the region. Models show the next
system for early next week ejecting out of the central Plains
(NE/IA/KN/MO vicinity) as a flat/compact southern stream
shortwave and weak sfc low tracking eastward through the Ohio
Valley toward the DelmarVA. The majority of the ensemble
guidance continues to show the bulk of the precip with this
system remaining to our south, though there is the potential for
some mixed precip to move through the southern half of
Pennsylvania.

High pressure edging southeast from the Great Lakes appears
deliver a dry period around midweek/Wednesday before precip odds
trend higher into the end of next week. Most guidance shows this
system tracking to our west, which would result in an all rain
scenario.

&&

.AVIATION /18Z SUNDAY THROUGH FRIDAY/...
Main issue this afternoon and into Monday will be gusty winds
from the northwest. Wind gusts this afternoon to around 50 mph.

Winds on Monday will be not quite as strong.

Other issue will be bands of lake effect snow showers off the
Great Lakes into BFD, and perhaps JST, AOO, and UNV at times.
Less likely to the east and south at IPT. Even less likely at
MDT and LNS.

The snow intensity could increase briefly around sunrise on
Monday, as the cold air deepens, and before midday, when bands
normally break up some.

Much of the rest of week will feature mainly dry conditions,
but chances from time for some light precipitation. First
such system would be late Tuesday, mainly across the southwest
PA.

Outlook...

Tue-Friday...Chance of a shower, but overall mainly dry
much of the time.
