Could Be A Storm, Will Be Heat

It's a warm morning around the region as we start off in the 70's through the Delaware Valley.  In the wake of last night's thunderstorm activity to our north and northeast, a cool front is crossing Pennsylvania this morning and has triggered a couple of thunderstorms up near Scranton as of 4 AM.  Those storms will push southeast and east into North Jersey over the next couple of hours.

As the front pushes southeast through the region today, the threat of a storm developing does exist...late this morning to the north and northwest of the city, this afternoon for the city and points south.  The threat isn't very high as the dynamics aren't altogether there for a widespread storm event...which means isolated to perhaps scattered storms may be the best bet.  Any thunderstorm that does develop does have the potential for gusty winds and perhaps hail but the best chances for severe weather will be to our south and southwest today (Maryland, Virginia, West Virginia, and North Carolina).  In essence, a passing, pop up storm along the front may be the best bet for any rain of substance today.

Once the front pushes through, winds will shift from southwest to northwest and become gusty, reaching perhaps 30 miles per hour in top gusts this afternoon.  Those drying northwest winds will help lower humidity levels and perhaps bump temperatures a couple of notches thanks to the downslope effect.  High temperatures will reach the middle 90's along I-95, around 90 at the Shore.  It will be a hot day but the worst of the humidity will be behind us by the peak of afternoon heat as dew points drop into the lower half of the 60's.
