Slight Risk Of Severe Weather Tomorrow
The higher resolution NAM from Penn State paints the potential as being greatest in the afternoon and early evening hours -- the above graphic is for 8 PM Friday night, showing the potential for some clusters of thunderstorms around the East Coast from Southern New England down through the Delmarva. Storms could be an issue as early as early afternoon on Friday as the frontal boundary approaches and a trough develops downwind from the front along the Appalachian Mountains. This "heat" trough is typical on hot days in the summer and can serve as a focus for thunderstorm development. Storms will develop near/along the front and push east, likely scattered in nature through the course of the afternoon. Not everyone gets thunderstorms but those that do could run the risk of seeing some strong storms and heavy rainfall.
