August 8th, 2012 Forecast

Higher dew points will creep back into the picture starting late tonight and tomorrow as high pressure's influence on our weather begins to slowly wane.  While temperatures won't really warm dramatically over the next three days, generally holding near 90 degrees like we did yesterday and will today, the added humidity will make it feel more 'ugh' outside.  The additional moisture also means the threat for pop up thunderstorms in the afternoon each of the next two days before a wider threat of thunderstorms hits us on Friday.

Tonight's weather should generally be ok -- a mix of clouds and stars through the night as low temperatures bottom out in the mid 60's in the coolest burbs, low 70's at the Shore and in Center City with light winds.  We don't rule out the possibility of a shower or storm south or southwest of the city later tonight but those odds are pretty low.  Some pop up thunder will be around tomorrow afternoon -- best chances will be to our west and southwest -- and any storm that does fire could produce locally heavy rainfall and gusty winds. Highs will flirt with 90 in many locations -- and get to the upper 80's where it doesn't hit 90.

Friday into Saturday looks like another widespread thunder threat for the region -- some storms may be severe on Friday afternoon and evening in parts of the region and, like last Sunday, some areas could see some rounds of heavy rainfall as a frontal boundary slowly slogs through the Delaware Valley.  The thunder threat looks to continue into Saturday, ending slowly from west to east over the course of the day.  We'll have more on the thunder threat for the weekend as we approach Friday.
