Thunderstorms are expected across much of the Upper Midwest on Wednesday. However, uncertainty is too high at this time to pinpoint where, or how much, strong to severe thunderstorm activity may develop.
Storms should remain non-severe for most of Pennsylvania as of right now. The outlook could change from now until Wednesday and will be updated IF changes do arise. Be sure to keep an eye open for any updated forecasts that may be written.
