Monday's climate report

Labor Day was another hot and humid day; at Philadelphia International Airport after a very humid low of just 74 this morning the high only reached 89 with sunshine giving way to clouds in the afternoon. There were also some showers and thunderstorms, but officially at the airport only 0.01" of rain fell(but technically it was from leftover showers overnight Sunday).

Overnight there may be an isolated shower or thunderstorm before Midnight, but otherwise it will be partly cloudy(some fog could develop in the Pine Barrens and higher elevations north and west) with lows ranging from the upper 60s to lower 70s in Center City. Tuesday will feature sunshine to start the day, but then clouds will bubble up once again in the afternoon ahead of a cold front; highs will be in the lower 90s with a southwesterly wind. There will be showers and thunderstorms in the late afternoon into the evening thanks to the cold front pushing on through, but the bulk of the precipitation will be overnight with lows in the muggy lower 70s.

Wednesday will start off with a few clouds, but as high pressure settles in from the north we'll have a northerly wind that will dry us out; sunshine will be the name of the game in the afternoon with highs in the middle 80s. The same shall go for Thursday as well with highs once again in the middle 80s and sunshine mixed with fair weather cumulus in the afternoon.

Come Friday there will be a surge of warm air pushing northward and the humidity will return as well; highs will be in the upper 80s, but the showers and thunderstorms will hold off until Saturday with highs near 90. Sunday will be in the middle 80s with showers and thunderstorms in the afternoon as the cold front pushes through and clears out by Monday.
