Columbus, Ohio — One hundred sixty million Americans are prepared and monitoring what forecasters say is shaping up to be the largest snowstorm of the season, as winter storm warnings remain in effect across large portions of Ohio and Pennsylvania through Monday, Jan. 26.
For this region, the first phase of the storm is expected to fall primarily as heavy snow. According to the National Weather Service, much of northern and central Ohio, along with central and northern Pennsylvania, is likely to see snowfall totals exceeding one foot, with locally higher amounts possible near Lake Erie and across higher terrain in Pennsylvania.
The National Weather Service Weather Prediction Center places the Ohio–Pennsylvania corridor within a high-confidence zone for moderate to heavy snow impacts from Friday through Sunday. Snowfall rates may exceed one inch per hour at times, sharply reducing visibility and creating dangerous travel conditions along major routes, including Interstate 70, Interstate 71, Interstate 80, Interstate 76, and Interstate 79.
Transportation officials in both states warn that prolonged snowfall could lead to extended road closures, disabled vehicles, and major delays for emergency responders and freight traffic. Snow-covered highways, blowing snow, and rapidly changing conditions may make travel unsafe or impossible during peak periods, particularly overnight and early morning hours.
Residents are urged to complete storm preparations before conditions deteriorate, including stocking food, medications, and emergency supplies. Motorists are advised to avoid non-essential travel during periods of heavy snowfall and to monitor roadway conditions closely if travel cannot be postponed. Commuters, students, and delivery drivers should expect disruptions that may last into early next week.
Behind the storm, a surge of Arctic air is forecast to settle across Ohio, Pennsylvania, and the broader Midwest and Northeast. Temperatures are expected to plunge well below seasonal averages, with dangerous wind chills locking snowpack in place and prolonging hazardous conditions even after snowfall ends.
While a brief lull in snowfall is possible between Jan. 28 and Feb. 1, forecasters caution that the overall pattern supports continued cold and winter weather into early February, limiting melting and extending impacts across both states.
