Although we don’t expect this to be a significant event, the Storm Prediction Center has upgraded NE-PA to a slight risk. Their discussion mentions this, “SLIGHT RISK FOR HAIL…WIND…AND PERHAPS A BRIEF/WEAK TORNADO.” The slight risk covers much of Eastern Upstate New York as well, and if there were to be a brief tornado it would likely be in New York, however with that said the Northern Poconos can not be ruled out of this risk.

The rest of Eastern Pennsylvania is at a marginal risk for seeing these severe thunderstorms, including locations such as Philadelphia, Allentown, Reading, Lancaster, Harrisburg, Williamsport, York and surrounding areas. If supercell thunderstorms were to develop, they would likely be across far NE-PA. There is no specific timing besides just overall Friday Afternoon/Evening, as these will be pop-up storms rather than an organized line. Below is the Storm Prediction Center’s Risk Map.
