After a hot, muggy, and stormy end to the work week, the weekend will be much more tranquil.
Saturday has started off with a patchy fog, which has been rather dense locally. Visibilities were reduced down to a 1/4 mile in a few spots early Saturday morning.
Weak high pressure will build in today bringing drier air. We can expect sun and clouds on Saturday with less humidity than Friday. But it won't be quite as warm either.
A stray shower or thunderstorm is possible, with chances more to the north of Philadelphia in the afternoon/evening.
A note: If you're going to be outside, stay well protected. UV Indexes will be very high at 9.
Enjoy your weekend!
