September 6th, 2012 Forecast

The tropical torrent of rain of the past few days will end this evening as the front pushes through, bringing an end to the threat of showers and storms overhead.  The thunder threat should subside from northwest to southeast over the next few hours, with lowering humidity levels moving in.  Despite the lower humidity, it will still be somewhat muggy as we work into Thursday.  Dew points will be in the 60's instead of the 70's -- but it's an improvement over what we're dealing with now.

Any storms over the next several hours could produce locally heavy rains, mainly south and east of Philadelphia, but these will diminish with the setting sun or push off the coast.  Fog is possible later tonight given the amount of ground moisture in place, the relatively humid atmosphere, and light winds.

Any morning fog will lift tomorrow, leaving us with a mix of sun and clouds for the duration of Thursday.  A stray shower or storm can't be ruled out in the afternoon with a weak disturbance pushing east in the wake of the first front.  Highs tomorrow get into the upper 80's, with a 90 degree reading or two not out of the question in parts of the region.
