Ice coverage across the Great Lakes region remains well below normal (5% total) given recent well above normal temperatures across all of the lakes. Ice concentration through the region is limited to the sheltered bays and shoreline areas of the northern and western Great Lakes. As of this afternoon, the notable ice coverage areas were located around the Apostle Islands region of Lake Superior, Green Bay and the Bays de Noc on Lake Michigan, and Saginaw Bay and the St. Mary's River and the far northern portion of Lake Huron. Any ice remaining on Lakes Erie and St. Clair is extremely thin and decaying with the warm temperatures and strong winds today. A cold front will move through the region by mid-day Saturday and high pressure with Canadian origin will enter for Sunday. Temperatures will fall closer to normal values across the region, but they will still be a few degrees above normal, just not the near record highs that the southern half of the region saw on Thursday and Friday. A clipper system will move through early in the week and merge with a southern stream system just southeast of the Great Lakes and some colder air will stick around for the first half of next week, as some more clipper type of systems move through the region during the week. Temperatures near normal may allow for some marginal ice growth, especially in the northern and western lakes. However, there does not appear to be a drastic Arctic cold outbreak on the horizon that would support rapid ice growth.
