Latest Forecast
A vigorous cold front will traverse the mid- Atlantic States from west-to-east tonight and be accompanied by heavy, gusty showers. Behind the front, much cooler and drier air will pour into the Commonwealth on Thursday with highs a few degrees below normal. Westerly winds of 10-20 mph with gusts up to 30 mph will make the outdoor air feel even chillier. A low pressure system will then develop near Long Island Thursday evening and retrograde northwestward into the Catskills or Poconos later Thursday night into Friday. As this occurs, scattered showers will move back into south-central PA, and a pocket of cold air on the system's southwestern flank could cause snowflakes to mix in with the rain or rain to briefly change over to all snow Friday morning. However, no snow accumulation is expected in the Lower Susquehanna Valley. Cloudy and blustery conditions will also persist Friday into Saturday with northwesterly gusts up to 30 mph.
