Latest Forecast
Tonight, clouds will return in advance of an approaching warm front, and a few light showers may reach southeastern PA Saturday afternoon. However, rainfall amounts should not exceed one tenth of an inch, and much of the day will be dry. Following Saturday's warm frontal passage, an upper-level ridge, or northward bulge in the Jet Stream, will build over the eastern United States from Sunday through Tuesday. As a result, the second half of the weekend will turn out partly sunny and much warmer with high temperatures around 15 degrees above average Sunday afternoon. The above average temperatures will persist into Monday with mostly sunny skies.
