Sunday will be the beginning of a stormy stretch in here in Pennsylvania. It’s been a slightly quieter than normal start to severe season around here, but this week will bring a sizable uptick in that category. Hit or miss thunderstorms are in the cards for Sunday, followed by a line of storms possible Monday Night that could be rather rowdy and may wake many of us up. But let’s get started with Sunday.

The main risks for Sunday are isolated damaging winds, hail, and maybe one tornado in the state. Storms will fire up across Western and Central PA early to mid Sunday afternoon, and push east into Eastern PA by the evening. They will be hit or miss, with some being garden variety and others possibly rather strong. Below is the Sunday severe setup.

We know, with the other wording on the graphic you may wonder how it’s only a slight risk. The Storm Prediction Center has their risk categories and all weather outlets are generally expected to relay their information to keep things consistent. However, every area of the US has their own definition of severe weather risk, really depending on the average frequency and intensity of severe weather in their area. Just know that Sunday is about a two out of five in terms of risks posed by the setup – if that helps at all.

Below is the latest Hi-Res NAM model’s future radar, showing those storms developing in the western half of the state early Sunday afternoon and moving east as the day goes on.

Finally, below is the Storm Prediction Center’s risk map for Sunday, showing the greatest risk for scattered severe thunderstorms across the eastern two-thirds of Pennsylvania.

Be sure to pass this article along to family and friends who have outdoor plans for Sunday, as this may be an inconvenience.

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!
