Latest Forecast

Three disturbances moving northeastward from the Ohio Valley and along the spine of the Appalachians will spark rounds of primarily afternoon and evening showers and thunderstorms through Saturday. The main threats from the storms will be frequent lightning, blinding downpours and localized flash flooding of low-lying, urban- and poor-drainage areas, but a few damaging wind gusts may also occur. Ahead of the disturbances, southwesterly flow will pump hotter and even more sultry air into the Lower Susquehanna Valley. High temperatures should be near 90 degrees this afternoon and in the upper 80s on Friday and Saturday with dewpoints in the mid 70s and peak heat indices of 95-100 degrees. If you have prolonged, outdoor plans, drink plenty of non-alcoholic beverages and take breaks in the shade or an air-conditioned room.
