As Hurricane Laura continues to move inland, we will be monitoring that and also the threat for severe thunderstorms here in Pennsylvania Thursday (not associated with Laura).

The weather has been quiet for a while, but we are once again having a lot thrown at us at once.

Potent clusters of severe thunderstorms with…
UPDATE: This threat shifted more to Sunday AM. A Slight Risk is still up for the late afternoon and evening, but severe thunderstorm activity looks to be very isolated.

The frequency of days with severe weather continues to increase as we move into the more active months of the season, and after a long-tracked derecho knocked out power to over half a million customers in Pennsylvania last week, more storms are likely again Wednesday.
