Early in the event, there will be a tornado threat before evolving into a squall line.

A Look Ahead
An area of low pressure will develop across the Rockies and track northeastward across the Great Plains and into the Great Lakes. Snowfall will develop along the northern side of the low Tuesday into Wednesday as cold air moves southward out of Canada, There is the potential for at least a few to perhaps several inches of snow across portions of the Upper Midwest and western Great Lakes. In addition, gusty winds will likely develop within the vicinity of the low and produce areas of blowing snow.
