Throughout the day today, a cold front will make its way through much of the state. With this front, temperatures will drop below freezing, and adequate moisture will be present over Lake Erie due to the lake's warmth. This will cause lake effect snow across northwestern Pennsylvania, especially in Elk, Forest, McKean, and Warren counties.

Snowfall amounts of 6 inches or higher are possible in the strongest parts of the band.

5PM simulated radar - Strong showers and squalls are present in north central Pennsylvania.

12AM Monday simulated radar - The lake effect snow band takes shape across northwestern and north central Pennsylvania.

5AM Monday simulated radar - Lake effect snow band continues across Crawford, Erie, Forest, and Warren counties.

This snow may cause business delays and closures on Monday as the snow will persist into Monday morning. The most likely areas to see a business or school delay and closure are in McKean and Warren counties.
