Weather/Pennsylvania/Mars
Coming up. Rain is likely this afternoon, from about 12 PM, the chance peaking at 77% around 1 PM.
Now. Mars is 70° and mostly cloudy at 5 AM. The dew point is 68°, so the air feels oppressive. Light breeze from the southwest at 7 mph.
Today and tonight. The warmest of the day has passed; it cools to about 52° by 8 PM. Tonight falls to about 38° by 6 AM, with some cloud. Air quality is moderate (index 52): fine for most people, though people unusually sensitive to air pollution may feel it outdoors.
The week. The warmest day ahead is Tuesday, near 67°, and the coolest tomorrow, near 51°. Rain is likely tomorrow (50%). The first freeze could come Sunday, a low of 31°.
