Latest Forecast

A vigorous, upper-level disturbance and its associated cold front will sweep through the Northeast this afternoon into tonight. The Lower Susquehanna Valley will be on the southern periphery of the disturbance, but a stray shower or gusty thunderstorm cannot be ruled out between 3-9 PM, especially north of the Turnpike and east of the Susquehanna River. However, most of the afternoon will turn out partly-to-mostly sunny and dry with moderately high humidity and highs in the upper 80s to perhaps low 90s. Behind the cold front, a Canadian high pressure system will settle into the Commonwealth and promote sunny skies and pleasantly warm conditions on the 4th of July. Humidity will be much lower, as well, with dewpoints only in the mid-to-upper 50s, and the weather should be perfect for outdoor activities and evening fireworks displays! Temperatures will fall through the 70s between 8:30-10:30 PM under clear skies. The area of high pressure will remain in control of the weather on Saturday, so another beautiful day is on tap. Much like Friday, skies will be mostly sunny with high temperatures in the mid 80s and dewpoints in the upper 50s to low 60s. There will be no weather-related issues for family gatherings, picnics, barbecues or vacations to the Shore this holiday weekend.
