Black Ice Overnight, Another Storm Coming

Overnight freezing will cause patchy black ice and slippery spots early Sunday morning. However,  an even bigger headache for drivers will occur during the Monday morning rush when a clipper system hits the region.

A Nor'easter that lasted Friday night into Saturday dropped up to seven inches of snow in parts of the area. Just as the area finally cleared the snow, we're preparing for yet another system to move in.

Before the snow hits, there will be the threat of black ice. Leftover slush and snow caused re-freezing on roads Saturday night. The slippery spots will last until around 9 a.m. Sunday when temperatures rise above freezing. If you're going to be out on the roads late Saturday or early Sunday, drive with caution. 

Sunday afternoon will be clear and partly sunny with highs near 39 degrees, making for a mostly pleasant and dry winter day. But another "clipper" storm will move in and bring even more snow to the region just as we head into the work week.

The snow should move into Lehigh County around 10 p.m. and the Philadelphia area after 11 p.m. The snow will last overnight into the Monday morning commute. Monday afternoon into Monday evening snow, both light and moderate, will continue to fall until it finally begins to clear around 11 p.m.

Estimated Snow Totals

Poconos/Lehigh Valley - 1 to 2 inches

I-95 Corridor/Philly/North and West suburbs - 2 to 3 inches

Central Delaware/South Jersey - 4 to 6 inches

Coastal Delaware/Jersey Shore - 3 to 4 inches

After Monday's clipper system, we may not be done with the snow yet, depending on what happens when the system moves off shore. The system could track closer to the coast again overnight into Tuesday morning which could lead to heavier and higher amounts of snowfall right along the shore.
