Latest Forecast

Westerly winds of 12-25 mph will direct unseasonably warm air into southeastern PA this afternoon. Under mostly sunny skies, high temperatures will be around 15-20 degrees above normal, or generally in the mid-to-upper 80s. A storm system will move from the Ohio Valley into the mid-Atlantic States spanning Wednesday night to Thursday. Clouds will increase ahead of the system Wednesday night, and widespread showers and thunderstorms are expected on Thursday. However, the severe weather threat appears minimal north of the Mason-Dixon Line due to lower temperatures, cloud cover, and a lack of instability. On the heels of this system, a second storm system will arrive on Friday and bring periods of steadier rain and drizzle to the Lower Susquehanna Valley. Due to the rain and clouds, highs will struggle to reach the 60-degree mark Friday afternoon.
