The swath of uniform precipitation is set to clear the area by late morning but scattered snow squalls are likely to re-develop during the afternoon due to a strong northwesterly wind flow.
Snow squalls will locally reduce visibility and contribute to addition snowfall accumulation.
Plan for 1-2 inches in Philadelphia through the day with higher totals to the north and west. The Lehigh Valley is forecast to pick up 2-4 inches of snow and generally a coating to an inch along the coast.MORE NEWS: Body Found At Broomall Auto Body Shop Owned By Missing Man George Hughes, Police Say
