CWS Forecast: Southeast Pennsylvania

After some residual snow squalls clear out over the northwest portion of the state overnight Thursday into Friday morning, the rest of the commonwealth will remain relatively dry for the most part until Saturday. A coastal storm will ride up the coast, bringing snow to much of the I-95 corridor, including southeastern parts of the state through Saturday night. As this coastal storm begins to exit, a weaker disturbance will move in through the Western portion of the state, bringing more light snow to western and central parts of the state, particularly to higher elevations into Sunday morning. Through the weekend, it will remain chilly, and lake effect snow could also begin to fall by Monday morning in northwestern parts of the state. Finally, we are watching another clipper system on Tuesday that could bring some light snow, but since it is far out, more details will follow in the days to come.
