May 31st, 2011 Forecast

It's hot and humid today in the Delaware Valley -- perfect to spend the day at the beach, shore point, or near some body of water.   The heat will continue for the next couple of days, not as humid tomorrow but still plenty warm around the Delaware Valley.

A weak trough will slip south this evening and try to ease cooler air in from New England.   While the surface wind trajectory will be light from the east and northeast tonight and tomorrow, we have a rather strong ridge of high pressure aloft that will keep the atmosphere plenty warm.   The heat ridge should be able to compensate for the attempt at a backdoor front, especially inland where temperatures will again runs towards and past 90 degrees.   East of I-95, however, it might be a few notches cooler during the day and the seabreeze may have a much easier time of marching west during the afternoon.   Expect 80's east of the city, 70's at the Shore tomorrow afternoon.  Everyone should be mostly sunny tomorrow.

We'll be starting Tuesday with mostly clear skies and morning lows in the upper 60's in the coolest burbs, mid 70's in the city.   A pop up storm or two can't be ruled out across the Poconos or Central Pennsylvania's higher hills.
