Risk Of Thunder This Evening In Some Spots

While this afternoon is going to be hot and humid as temperatures approach the middle 90's in spots, the risk for some thunderstorms does exist.  A disturbance is approaching the region through the Ohio Valley, with showers and storms firing up across Western and Central Pennsylvania later today.  As of 9 AM this morning, radar shows the disturbance responsible for this afternoon's pop up thunder threat pushing north through the Ohio Valley.

Scattered thunderstorms will pop up this afternoon to our west (out towards Johnstown, State College, Altoona) and will gradually push east and northeast through the balance of the afternoon and into the evening hours.  A slight risk of severe weather is out (just updated as of 12:15 PM) for Eastern/Central PA, pretty much along/northwest of I-95.

Additionally, heavy rainfall can't be ruled out in any stronger storm that fires up later on.  The key in today's storms is scattered, not widespread.  Philly should make it to the dinner hour without any thunder threat and perhaps make it through tonight as well because of the scattered nature of the thunderstorms that should pop up later.  Our part of the world should see some of these storms move through after 6 PM, closer to 6 west and later on in the evening the farther east one is.
