Another arctic front will move across the Great Lakes next week bringing another surge of very cold air. This cold arctic air will pass over the warm waters of the Great Lakes, possibly resulting in significant snowfall over a few days next week.

The large temperature difference between the very cold air and the warm lakes may create enough instability that lightning and thunder may even accompany the snow at times.

Lake Superior and Lake Michigan will first see the lake-effect snow Sunday into Monday. Snow is expected to fall south of Lake Superior and east of Lake Michigan with several inches of snow piling up.

Then more significant snow will develop off of Lake Erie and Lake Ontario Monday night into Wednesday. Another disturbance will move through on Wednesday, with additional lake-effect snow developing behind the system.
