Philadelphia Labor Day Weekend Forecast - Thur AM
High pressure that has kept our area dry for the past several days will drift off, as a southwesterly flow of warm very humid air moves in. A busy, complicated weather scenario for the weekend:
A developing tropical system in the Gulf of Mexico will be feeding this humid flow. A developing upper level trough and cold front will be approaching slowly from the west. (A hurricane (Katia) in the Atlantic will be approaching but will likely turn away from the coast.)
Tropical systems in the picture often play havoc with the forecast by interacting with the jet streams in unpredictable ways--A lower than usual confidence forecast for this weekend.
Sat 9/3: Partly sunny, but periods of some cloudiness in the afternoon. Humid. High 85. Showers develop at night.
Sun 9/4: Considerable cloudiness, some breaks of sun possible. Very warm and humid. Chance of scattered showers and possible thunderstorms throughout the day. High 88.

Mon 9/5: Mostly cloudy. Very warm and humid. Chance of scattered showers and possible thunderstorms. High 83.
