Final Call Snowfall Forecast for Thursday’s Rain to Snow Event + Lake Effect

Model data have come into agreement in the past day, resulting in a final call very similar to our first call. Rain will change to snow in northwest PA around lunchtime Thursday, and the rain/snow line will work its way southeast from there. North-central PA will change to snow around 3-4 PM. Northeast PA, as well as southwest PA, will change to snow around 5-7 PM.

Highest snowfall accumulations will be above 1300′ elevation, due to colder temperatures allowing for more accumulation. Scattered lake-effect snow will then take over by Thursday evening in western PA, continuing into Friday morning. Heaviest accumulations will be near the lake, but brief heavy snow squall will be possible across the western half of the state Thursday evening into Friday morning.

FUTURE RADAR

By 2 PM Thursday, light to moderate snow will be falling in northwest PA.

By late Thursday evening, snow will begin to wrap up in northeast PA, and lake effect snow showers will roam western Pennsylvania. Here is 9:00 PM Thursday future radar.

Finally, by early Friday morning, just scattered lake effect snow showers leftover in western PA.
