Updating Shower & Storm Threat Into The Evening

Showers and storms around the region are becoming a bit more numerous as we work through the late afternoon and early evening hours.  Shower and storm activity so far today has been scattered in lines with the greatest concentration of shower activity to the north and west of the city.  Up towards New York City, some of the shower activity that moved through the northern & western burbs earlier this morning turned into torrential downpours that produced upwards of two to three inches of rain per doppler radar estimates and lead to ground stops at LaGuardia Airport.

Locally, scattered rains have generated between trace amounts and an inch or so, with the inch type amounts out towards Reading, Lancaster, and north towards Stroudsburg.

Shower trends as we work into 5 PM are such that New Jersey is getting hit a bit harder than Pennsylvania, with North Jersey continuing to see lines of showers and storms repeatedly tracking over the same general areas.  More scattered showers in a broken coverage exist to the west of the city.  Everything's lifting northeast.  That will be the trend this evening.

The cool front that separates summer from spring is currently across Western PA.  You can see the 60's out by Pittsburgh and the 59 in Erie while we're in the 70's and 80's over here.  The front is west of State College yet and will slowly work east through the evening, likely crossing the city around or after Midnight.  Tomorrow may be one of those days where the high takes place in the pre-dawn the front crosses it slows further and upper level energy will move in and produce showers and a brisk northwest breeze.  Going from summer to April in about 24 hours!

The threat for severe weather does exist, albeit it's pretty low this evening as the shower activity that's fired up through the afternoon hours is helping stabilize the atmosphere a bit from a severe weather perspective.  That said, the threat for heavy rain does exist through the evening in any of the stronger showers that do fire up across the region.
