Harrisburg, PA – A surge of Arctic air is set to sweep through Pennsylvania early next week, delivering the coldest temperatures of the season so far. According to the NOAA Weather Prediction Center, a sharp cold front will push across the state Monday, November 10, followed by a widespread freeze and gusty winds through Tuesday morning, November 11.
Lows are forecast to dip into the upper-teens and low-20s across the Laurel Highlands and northern tier, with mid-20s to near 30 expected from Pittsburgh to Harrisburg. Even Philadelphia suburbs may flirt with freezing by dawn Tuesday, marking one of the most widespread early-season freezes in recent years.
The Weather Prediction Center’s Day 3–7 Hazards Outlook places Pennsylvania within a broad “Frost/Freeze” risk zone stretching from the Gulf Coast to New England. Behind the front, brisk northwest winds gusting 25–35 mph will funnel in Arctic air, producing wind chills in the teens across western and central parts of the state.
Forecasters say lake-effect flurries are possible in northwestern counties Monday night, with otherwise dry but sharply colder weather statewide. Daytime highs Tuesday will struggle to reach the upper-30s to low-40s — roughly 15 degrees below normal.
Residents are urged to take precautions for the cold: bring pets indoors, cover outdoor spigots, and protect sensitive plants ahead of Monday night’s freeze. Motorists should be alert for icy spots on bridges and overpasses during the Tuesday morning commute.
The chill will persist through midweek before a gradual warming trend returns by Thursday.
