Today's high of 83 was the warmest day we've had in Philadelphia since April 10th and our third warmest day of the year. It's coming with a bit of a price as thunderstorms are firing out to our west with a disturbance pushing northeast through the Ohio Valley and into the Northeast.
Radar as of 6:45 shows a quiet screen locally but thunderstorms are as close as Harrisburg and also State College and Altoona, all lifting northeast.
The batches of thunder near Harrisburg should work through Allentown, Quakertown, and Reading over the next couple of hours, with the thunderstorm activity down in Virginia and West Virginia the activity that pushes northeast towards us later this evening. The part of the line across Virginia and West Virginia is not as active as the Pennsylvania portion of the line, which has dropped 60 mph winds and one inch hail earlier this evening near Altoona. Those storms will not impact us directly as their northeast movement will push them into New York State later on.
There is no severe weather threat for our region but the storms near Harrisburg could drop gusty winds on Allentown and Reading...that's about the "worst" expected threat around here.
These showers and storms will likely move on in after 8 in Allentown and Reading, with the southern portion still a few hours behind and probably not into the city until after at least 10 or 11 PM.
