Latest Forecast

A sprawling high pressure system over the Ohio Valley and mid-Atlantic States will promote mostly sunny, breezy and pleasantly cool conditions this afternoon with high temperatures in the mid-to-upper 70s. The area of high pressure will shift into the western Atlantic on Thursday but remain in control of the weather across the Lower Susquehanna Valley. As a result, another partly sunny and beautiful day is expected with high temperatures around 80 degrees. Low temperatures will be around 50 degrees tonight and in the upper 50s Thursday night, and humidity will remain low through Labor Day Weekend. A weak cold front will traverse the Commonwealth from northwest-to-southeast spanning Thursday night to Friday morning, but it will be starved for moisture and only bring a stray shower to central and southeastern PA. Most of Friday should turn out mostly sunny and dry with high temperatures similar to Thursday. Overall, this week's weather will be fantastic for outdoor activities and sleeping with the windows open at night!
