Update On Tonight's Weather

As for 4 PM there have been two general areas of rain so far. One in New Jersey with a surface wave of low pressure traveling out in front of the cold front and the second over the western suburbs of Philadelphia. In both regions upwards of an inch of rain has fallen in quick bursts of tropical rain.
The current radar (shot above taken at 4:25 PM) suggests a quiet few hours ahead before the main cold front works east through Pennsylvania. Expect another round of rain to break out after 6 or7 PM in the western suburbs spreading east and northeast throughout the region throughout the evening. Like the rainfall earlier today, some heavy amounts over an inch are expected. Rain should cut off between 11 and 2 in the region with the frontal passage. Humidity levels will drop off as well.

The potential for severe thunderstorms seems to be lessening somewhat thanks to increased cloud cover and the presence of the low pressure wave earlier in the day in New Jersey. However, gusty winds can be brought down to the surface in any shower or storm so a few severe warnings are not out of the realm of possibility this evening.
