Low ice coverage across the region became even lower over the weekend due to the above normal temperatures. The Great Lakes stands at 3% total ice coverage across all basins, most of which is in the Canadian waters of the Great Lakes. Ice concentration through the American waters of the region remains 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 in Chequamegon Bay in Lake Superior, the Bays de Noc and the edges of Green Bay on Lake Michigan, and a tiny amount in the central portion of Saginaw Bay in Lake Huron. Lakes Erie and St. Clair are essentially ice free. A trough will move through the region tonight into Tuesday and bring some more seasonably colder area across the area. Most locations will settle back toward normal temperatures for the remainder of the week behind this system. High pressure will enter from the north and sustain the cooler temperatures. A low pressure system will cut through the Great Lakes on Thursday and some slightly warmer temperatures are possible in the southern Lakes for just a day. Another system will target the region for the weekend and may bring some below normal temperatures. In the end, ice growth will be marginal at best for most of the week. If this colder system does enter for the weekend, there could be some notable new ice development in the northern Great Lakes towards the end of the forecast period.
