A clipper system (a fast-moving low pressure originating from Canada) will drop into the Midwest and Great Lakes Friday afternoon, bringing some widespread light snow through Saturday.
Starting at around noon on Friday, snow will begin to be seen in northern Minnesota. The clipper will track southwest, bringing snow to the rest of Minnesota, northern Wisconsin, and the western UP of Michigan during the afternoon. Overnight into early Saturday morning, snow is expected to fall across the northeastern corner of Iowa, southern Wisconsin, Illinois, and most of Lower Michigan. As you wake up Saturday morning, snow will likely be coming down in Indiana and will continue to fall in Lower Michigan.
Getting into the midday and afternoon hours, the snow will move into Ohio and northern Kentucky. At this time it will begin to break up into snow showers, causing the intensity to decrease. The reason for drop in intensity a storm off the Northeast coast will draw the energy of the clipper out to sea. However, snow will continue into the first half of Saturday night for the mountains of West Virginia. But by Sunday, this clipper will move back into Canada, ending its run in the US.
Overall, snow accumulations will be light for the most part, adding up to one to three inches for most locations. Along the northern coast of the Upper Peninsula of Michigan and near the western coast of Lower Michigan, snow totals will be higher. These locations may reach up to half a foot as the lakes will enhance snowfall rates, adding more moisture.
