Harrisburg, Pennsylvania – A mid-January warm-up could bring periods of rain to much of Pennsylvania while increasing the risk of freezing rain and icy travel conditions in colder regions as temperatures fluctuate near freezing.
According to the National Weather Service Climate Prediction Center, Pennsylvania is favored to see above-normal temperatures during the January 9–13 period, while precipitation trends near normal. This setup often supports rain across southern and eastern sections while allowing mixed precipitation farther north and west where colder air tends to linger.
Northern and western Pennsylvania, including Bradford, Warren, and parts of the Laurel Highlands, may face the highest risk for freezing rain, particularly during overnight and early morning hours. Even light ice accumulation could create hazardous travel on Interstate 80, Route 219, and higher-elevation secondary roads.
Across central and southeastern Pennsylvania, including Harrisburg, Lancaster, Philadelphia, and the Lehigh Valley, precipitation is more likely to fall as rain, limiting snow chances but leading to wet roads and reduced visibility during heavier showers. Brief nighttime cooling could still allow isolated slick spots to develop.
Drivers are urged to stay alert to rapidly changing conditions and allow extra travel time during the period. Additional advisories may be issued as the pattern becomes clearer closer to mid-January, especially if colder air presses farther south into the state.
