Harrisburg, Pennsylvania – Above-normal precipitation combined with near-normal temperatures may increase snow chances across Pennsylvania from Jan. 3–9.
According to the NOAA Climate Prediction Center’s 8–14 Day Outlook, much of Pennsylvania is favored to receive above-normal precipitation during the first full week of January. Temperatures are forecast to remain near seasonal averages, a pattern that supports snowfall potential across large portions of the state.
The outlook shows a 33–50% probability that precipitation totals exceed early-January averages. While the guidance does not identify specific storm systems, it points to conditions favorable for multiple snow events rather than a single major winter storm.
Northern and western Pennsylvania, including higher elevations and lake-influenced areas, typically experience colder surface temperatures that enhance snow accumulation potential. Central Pennsylvania may also see accumulating snow, while southeastern areas could experience snow or brief mixed precipitation depending on storm track and timing.
Travel impacts are possible along Interstate 76 (Pennsylvania Turnpike), Interstate 80, Interstate 81, Interstate 79, and major freight corridors. Commuters, students, healthcare workers, and long-haul drivers should be prepared for slippery roads and reduced visibility, especially during overnight and early-morning hours.
The Climate Prediction Center emphasizes that 8–14 day outlooks represent probability trends, not guaranteed outcomes. More detailed forecasts, including snowfall amounts and potential winter weather advisories, will be issued by the National Weather Service as individual systems develop.
Residents are encouraged to monitor updated forecasts, prepare vehicles and travel plans for winter conditions, and stay alert for possible winter weather advisories or warnings as early January approaches.
