Latest Forecast
Showers have ended across the Lower Susquehanna Valley and will exit southeastern PA by 2 PM. In their wake, this afternoon will be warm and humid but dry with high temperatures in the upper 70s to low 80s and dewpoints in the mid-to-upper 60s. A cold front will sag southward through the mid-Atlantic States tonight. Behind it, north-northwesterly winds of 10-20 mph will usher slightly cooler and much drier air into the Commonwealth on Thursday. As a result, skies will gradually clear tonight, and Thursday is expected to be mostly sunny and beautiful with highs in the mid 70s and dewpoints around 50 degrees. A Canadian high pressure system will settle into the Ohio Valley and eastern Great Lakes region from Thursday night into Friday and promote clear skies, light winds, low humidity and pleasant conditions. Thursday night will be fantastic for sleeping with the windows open, and Friday's weather will be perfect for outdoor activities.
