Tonight will be our first time below 70 degrees since the morning of June 23rd. It's not going to be as cool as we originally thought yesterday, but you'll still feel the difference in the airmass when you step outside tomorrow morning to temperatures in the 60s. Tonight's weather will vary depending on where you live. North and west of the city will have a partly cloudy night and a decent view of the bright moon. In Philadelphia and areas south and east, it will be mostly cloudy. A frontal boundary sitting off the New Jersey coast could bring a few showers to South Jersey and Delaware, especially late tonight. Lows will drop into the mid 60s in Philadelphia, to near 60 north and west, and into the low to mid 60s south and east.
Thursday will be much cooler than we are used to after the heat and humidity for the past month. Mostly cloudy skies will likely prevent temperatures from reaching 80 degrees in most places Thursday afternoon. A few more showers are possible from the frontal boundary, mainly from I-95 on south and east. Highs will mainly be in the upper 70s across the region with low humidity.
The frontal boundary will finally move away by Friday, leaving us with a pretty nice day. Saturday looks dry, but humidity will be back on the increase. A cold front will approach our area on Sunday, bringing with it scattered thunderstorms. The better half of the weekend will definitely be Saturday, although it won't be raining 100% of the time on Sunday.
Behind the cold front will be a comfortable airmass for the start of next week. High temperatures will be seasonable in the mid 80s with low humidity.
