Southeast PA Forecast

Basic CMYK

Our southeast PA forecast region includes Philadelphia, Doylestown, West Chester, Lancaster, York, Gettysburg & surrounding areas. Forecasts are updated daily M-F and Saturday that covers both weekend days – not Sunday. 


Warmth returns on Monday ahead of a cold front, scattered strong t-storms possible for some this evening…

A cold front approaching from the west will be delayed enough that for the majority of the region, Monday is warm and dry. We could start off with some patchy fog early in the morning, which will burn off and the sun will make a return, even if just partially. This evening we will have the opportunity for scattered showers and thunderstorms ahead of the cold front, which may be locally strong, especially in our westernmost counties.

Becoming partly cloudy Tuesday and still seasonably warm, and then mostly sunny with cooler temperatures on Wednesday. Another system will affect the region beginning later Thursday with periods of rain and cooler temperatures, which will likely linger into Friday with scattered showers and thunderstorms, and locally heavy rainfall will be possible. The system will meander close to the region on Saturday, which will keep things mostly cloudy with the chance for a passing shower or two, and then more improvement by Sunday. Both weekend days we project will remain below normal temperatures for this time of year.
