Harrisburg, Pennsylvania – A strengthening arctic cold front is expected to usher in a prolonged stretch of colder-than-normal weather across Pennsylvania late January into early February, with snow chances increasing mainly across southern and eastern parts of the state.
According to the National Weather Service Climate Prediction Center, the Jan. 24–Feb. 6 outlook favors below-normal temperatures statewide, while precipitation probabilities increase closer to the Mid-Atlantic storm track. This places southeastern and south-central Pennsylvania in a more favorable zone for winter weather compared to the drier northern tier.
Areas including Harrisburg, York, Lancaster, and Philadelphia could see one or more periods of snow or mixed precipitation as weak systems ride along the arctic boundary. Even light snowfall could create slick travel conditions on Interstates 76, 83, and 81, particularly during overnight and early morning hours.
Western and northern Pennsylvania, including Pittsburgh, Erie, and the northern tier, are expected to remain colder but generally quieter, with limited snowfall potential and subdued lake-effect activity due to limited moisture.
Cold-related impacts will be felt statewide, including icy patches on untreated roads, increased heating demand, and the risk of frozen pipes. Residents in southern and eastern Pennsylvania are encouraged to monitor updates closely as storm chances may increase toward the end of January.
Below-normal temperatures are expected to persist into early February, with additional advisories or alerts possible as the overall pattern becomes clearer.
