PHILADELPHIA (CBS) — Strong wind began whipping across the Delaware Valley early this morning. Now the soaking rain is changing over to wet snow as our moisture-rich Nor’easter moves inland, with cold air wrapping into the storm.

The Eyewitness Weather Team expects the heaviest precipitation Wednesday afternoon and evening — and we’ve updated our projected snow amounts:

A slushy 2-4″ – locally up to 5″ – will accumulate (primarily on the grassy/non-paved surfaces) from New Castle County, DE all the way up to portions of the Lehigh Valley through Wednesday night. ** This includes the cities of Philadelphia, Wilmington, and Trenton. Initially, any snow will have a tough time sticking to the roads. But if it falls heavily enough, especially after sunset, it will stick on some roads. Temperatures also dip back near freezing overnight, so icy spots may develop.

Meanwhile, heavy rain (1-2″ locally) is the main concern for the immediate shoreline.

Wind is of course the other concern – with gusts howling as high as 45 mph in Center City, peaking near 60 at the sensitive shore points. Additional coastal flooding is also an issue. The storm makes its departure Thursday with lingering rain and snow showers, the wind gradually tapering off.

A Winter Storm Warning is in effect for Philadelphia and the immediate surrounding counties through 6AM Thursday. Almost everyone else is under a Winter Weather Advisory.

Wind Advisories are out for Philly and the surrounding counties, while Coastal Flood Warnings and High Wind Warnings are in effect for the NJ and DE coasts.
