Final Update On Tuesday’s Clipper System

Snow will move into Western PA Tuesday Morning and spread east. We expect light snow to fall much of the day across Western PA and potentially through the mountains of Northern PA. As you work your way into Southern and Eastern PA, this is looking much more like a snow-squall type deal.

Snow squalls will move through Central PA Tuesday Afternoon and Eastern PA by the evening. Some areas could see over an inch of snow from these squalls and others may see nothing at all, if not hit by a squall.
