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.
