A powerful Central Plains system moves northeastward towards Upper Michigan and the Western Great Lakes region Thursday. The winter storm initially brings mixed rain and snow before fully transitioning to snow -- starting in the western counties late evening then east by Friday morning. The main hazards will be difficult driving conditions with accumulating heavy snow and limited visibility from blowing snow as winds gust over 35 mph -- 50 mph gusts possible near the Lake Superior shore. Snow production continues Saturday from the lake effect following system passage. Snow amounts through end of Saturday for most areas north will be around a foot with two-feet accumulation or more possible in higher terrain and in the north to northeast snow belt areas.
