State College, Pennsylvania – Arctic air is expected to remain firmly in place across northern Pennsylvania from Jan. 24 through Jan. 30, bringing an extended stretch of below-normal temperatures and reinforcing persistent winter conditions across the region.
According to the National Weather Service Climate Prediction Center, northern Pennsylvania falls within a roughly 70 percent probability zone for below-normal temperatures during the Jan. 24–30 period. Confidence is elevated that cold air will dominate with limited opportunities for meaningful warming before the end of the month.
Across the northern tier, including Potter, Tioga, Bradford, and McKean counties, daytime highs are expected to remain well below seasonal averages, while overnight lows frequently drop into the single digits and teens. Prolonged cold will allow snowpack and icy conditions to persist on roads such as U.S. Route 6, Route 15, and rural secondary highways.
In central northern areas, including State College, Altoona, and the Interstate 80 corridor, temperatures are also expected to stay below normal throughout the Jan. 24–30 window. Even during brief moderation periods, highs may struggle to climb out of the 20s, increasing the risk for lingering ice on untreated roads, bridges, and parking lots.
PennDOT urges drivers to remain cautious during morning and nighttime travel, when refreezing is most likely. Residents are encouraged to take cold-weather precautions, including protecting pipes, limiting prolonged outdoor exposure, and checking on vulnerable neighbors and pets.
The Arctic pattern shows little indication of breaking before the calendar turns, and additional cold-related advisories may be issued as confidence remains high in sustained below-normal temperatures across northern Pennsylvania through Jan. 30.
