As of January first, ice is forming on the south third of Green Bay and has formed on Chequamegon Bay on Lake Superior. Otherwise ice formation is minimal but shore ice is starting to form along the south shores of Lake Superior, the north shore of Green Bay, and the south shore of the Saginaw Bay. Much colder weather is in store to start January. Temperatures will cool across the Great Lakes Region through Saturday. Duluth can expect to see below normal temperatures from Friday through Sunday with rapid ice growth near the Apostle Islands and along the south shores. Ice will continue to expand on the Inner Saginaw Bay and on northern portions of the Green Bay. Confidence is lower but shore ice may start to develop west of the Lake Erie Islands over the weekend. Temperatures will warm slightly to start next week but will generally remain below freezing. Long range outlooks show arctic air arriving towards the middle of next week so look for ice growth to accelerate and water temperatures to cool more quickly.
