New Snowfall Predictions Released As Winter Storm Watch Issued In PA

PHILADELPHIA, PA — New snowfall estimates for a storm expected late Sunday night through Monday have been released by the National Weather Service. A winter storm watch has been issued in much of the region.

According to a Saturday evening briefing, the Philadelphia region can expect between 3 and 6 inches of snow, with higher amounts falling south and west of the city.

A winter storm watch is in place in parts of Delaware, Chester and Montgomery counties. "Plan on slippery road conditions. The hazardous conditions could impact the Monday morning and evening commutes," the National Weather Service warned.

Bucks and Montgomery counties are expected to get between 3 and 4 inches, with Chester and Delaware counties poised to receive a few more inches. However, "a small shift in the storm track could push the higher totals either north or south."

Snow will peak in intensity Monday morning but linger through the evening, the National Weather Service predicts.

"Accumulations are expected across most of the region, but higher amounts are expected generally south of the Interstate 195 and Pennsylvania Turnpike corridor, with highest totals in the Delmarva and southern New Jersey," the National Weather Service said in the most recent update.

It will remain windy and cold Monday. Expect winds to be around 20 mph throughout the storm, with gusts of up 25 to 35 mph possible overnight Monday.
