Another average day recorded at Philly International Airport; we reached a high of 86 after a low of 65 under sunshine and some fair weather cumulus passing by in the afternoon. Overnight we'll have a few clouds with lows in the middle and upper 60s.

Juicier air moves on Monday along with a threat of an isolated shower or thunderstorm(especially N&W) in the afternoon

Monday will start off sunny, but then we'll have clouds in the afternoon with a few isolated showers and thunderstorms due to a conditionally unstable airmass on top of the region; highs will be in the upper 80s with a southerly wind around 10mph and the dewpoint will be into the upper 60s. Now the front will wash itself off overnight so this means that highs on Tuesday will be in the lower 90s with a hazy, hot, and humid afternoon.

Come Wednesday a more potent front will inch closer to the region so the day will be very hot and humid with highs in the middle 90s(heat indices close to 100; I'd expect a Heat Advisory to be issued), but there will be showers and thunderstorms popping up by the evening commute. After overnight lows in the lower 70s it will be continued hazy, hot, and humid with highs in the lower 90s.

Unfortunately, the cold front will stall on top of the region so Independence Day will feature scattered showers and thunderstorms with highs in the lower 80s.....BUT the silver lining to this is that whatever tropical system forms along the Carolina coastline shall be pushed away from our shorelines thanks to that front. We shall see and I will keep you posted on that.
