July 9th, 2013 Forecast

A few evening showers and storms will scatter themselves around -- bringing a quick 20-30 minute hit of rain and thunder to some locations. Not everyone gets a shower or storm, just like last night, and once they move through the balance of the evening should be dry and quiet.  Humidity levels will drop a notch or two -- can't say it's outright relief but dew points will lower into the lower half of the 60's overnight and it should make for a slightly more tolerable night of sleeping for the air conditioner-less outside of the city.  Lows by morning drop into the 60's outside of the city, probably hang around 70 in the immediate city itself.

Tuesday's forecast, which originally looked dry even as recently as yesterday, is not looking quite so dry at this point.  A return surge of humidity will push east and northeast in the wake of the "relief" that works through tonight. Afternoon and evening thunderstorms are possible -- this might be an MCS or some type of storm complex that a few models are trying to track through Pennsylvania in the afternoon hours along an approaching warm front. Other high resolution models aren't as aggressive on the potency of the storms and suggest more scattered storms.  Either way, there's a thunder threat that we will sort through and update you on tomorrow morning.  Highs tomorrow flirt with 90 again in most locations along I-95 and south, a notch cooler north and west, assuming storms hold off until the afternoon.  An earlier thunder threat knocks the highs back a bit.  Our thinking is we get through midday dry.

Wednesday into Thursday offers a more widespread shot of thunderstorms as a cool front approaches the region.  The front approaches Wednesday, crosses Thursday, and appears to ease away on Friday.  The thunder threat will be higher on Wednesday in Pennsylvania and higher for us and east and south on Thursday.
