Outside of a few passing high clouds tonight, skies will be mainly clear. Temperatures will be cool and comfortable with a low bottoming out in the mid 50s in Center City. The Lehigh Valley may end up quite cool, perhaps in the upper 40s by daybreak. Most of the suburbs, however, will be between 50 and 55 for their lows.
Wednesday will be very similar to today, except we won't see 100% sunshine. Skies will still be mostly sunny, but there will be some clouds at times. Highs will reach the upper 70s in Philadelphia, the mid 70s in the suburbs, and the low 70s at the Shore.
Thursday will be a touch cooler but still seasonable with a mix of sun and clouds. Highs Thursday will be in the low to mid 70s.
Tropical Storm Andrea could be forming off the Florida coast later this week, and it could impact our weather on Friday and Saturday. All we'll have to worry about is remnant rainfall -- not much in the way of wind -- since it will likely lose tropical storm strength by the time it makes it this far north. The Euro and GFS are coming into better agreement and suggesting that most of the rain will fall on Friday with just a few leftovers showers or storms on Saturday. However, it still looks dry for the second half of the weekend, as of now. We'll certainly keep an eye on it for you throughout the week.
