Humid, Scattered Storms Later
Another run into the 90's today and another muggy day in the Delaware Valley. Excessive heat warnings remain out for the Delaware Valley region today as heat index values at peak heat could approach or briefly exceed 100 degrees given the combination of heat and dew points in the lower 70's. Heat advisories are out for the four South Jersey counties in orange as well as southern Delaware where heat index values could also flirt with 100 this afternoon for a time.
There are a few showers out west of Harrisburg early this morning that are moving east. These, if they hold, will scattered through the Delaware Valley after 7 AM. A decaying area of showers and thunderstorms is over West Virginia and pushing east-northeast. It has been on a clear weakening trend but it should spread a few sprinkles or showers around Delaware later this morning. More scattered thunderstorm activity looks to fire up later today. While locally severe storms are not likely, some gusty winds and heavy rainfall can't be ruled out in any storm that does fire. A slight risk of severe weather is out for the southern half of Delaware...areas to our south probably have the best shot at severe weather later today since they will get a bit more sun and didn't get in on last night's thunderstorms.
Highs this afternoon should get into the lower 90's locally, with 80's right along the Shore. Some spots in Lower Delaware could get into the middle 90's.
