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.





Heading into dinnertime, the rain/snow line will reach Pittsburgh, Williamsport, and Scranton. Below is future radar for 5:00 PM Thursday.

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.

Josh has been passionate about weather as long as his memory dates! From watching the Weather Channel at age 7, to making hand-drawn hurricane maps at age 11, starting his first weather site at 13, and founding PWA at 15 and forecasting for the state for the past 9 years, Josh's interest in weather has never dwindled! As difficult as it is, he greatly enjoys forecasting for Pennsylvania due to its countless microclimates. The state is an East Coast severe weather hotspot and nearly always home to the rain/snow line during winter storms!
