Broad low pressure will set up shop over the Great Lakes by the start of Monday. In so doing, it will pit widespread rain with an outbreak of cold air out of northern Canada. Where the two meet, it will become cold enough for snow over a part of the Upper Midwest.

A rainy stretch from northern Wisconsin and western upper Michigan will become prone to snow by late on Sunday night. This potential for snow will last through at least Tuesday morning.

By Tuesday, even more cold air will spiral southward over the Midwest as the parent storm swirls over Michigan and southern Ontario, Canada. It is possible that snow will be seen into lower Michigan, northern Illinois and northern Indiana.
