TODAY: Look for bright sunshine, low humidity and a nice, warm afternoon high of 82. It looks like perfect weather for Sail Philadelphia as the tall ships come up the Delaware during the afternoon.
TONIGHT: We're clear and comfortable with a low of 59.

FRIDAY: High pressure pushes just to our east and southwest winds on its back side warm us to near 87 degrees. Dewpoints climb up into the mid 50s. This is slightly higher than Thursday, but not very muggy.

SATURDAY: Dewpoints creep up to near 70, making for a real muggy to borderline oppressive feel. High temps reach 87 again, and enough instability exists for a few pop-up afternoon thunderstorms across the region. Where they hit, they will be soakers, with the atmosphere loaded with moisture. This looks to be the best day of the holiday weekend. Its 77 at the shore.

SUNDAY:: A backdoor cold front is approaching and moving through. As it moves into our area it will be the triggering mechanisms for numerous showers and t'storms across the region in our very humid airmass. From Saturday night through Sunday we could see a general " to 1" of rain across the region with locally higher amounts. Highs hit 82 in Philadelphia, 73 at the shore. This will be the worst day of the holiday weekend.

MEMORIAL DAY: The front may have pushed just to our southwest to allow for some drying in the upper levels of the atmosphere. This would shut off the rain and allow things to become more stable. Unfortunately, low level moisture does look to get locked in the bottom of the atmosphere giving us a mostly cloudy day due to low clouds. If we are lucky we may see a few breaks of sun late in the day. Overall its mainly dry, but can't rule out a spotty shower. The high slips to 78 (70 at the shore.)

TUESDAY: Morning clouds and perhaps a spotty shower subside fairly quickly and we see the return of sunshine. The high rebounds to 86.

WEDNESDAY: This looks like a nice, partly sunny day with another warm afternoon high around 79.

THURSDAY: Look for mostly cloudy skies with a high of 78.
