Snow cover expands across northern United States - WICU12/WSEE Erie, PA News, Sports, Weather and Events

We are now in the final four weeks of autumn, and snow cover is expanding south from Canada into the northern United States.  As of early this Sunday morning, 12.9% of the continental United States had snow cover.  Earlier this weekend, parts of northeastern Ohio, northwestern Pennsylvania and upstate New York gained some snow cover due to an episode of lake-effect snow. Early this morning, a few inches of snow fell across the Upper Peninsula of Michigan, as well as the northern part of the Lower Peninsula.  While we stay dry through most of the workweek, a storm system on Tuesday may paint a narrow stripe of fresh snow a couple hundred miles to our southeast.  Later in the week, a temporary warming trend will unfold, but it won't be long before Toledo's first inch falls.
