Motorists, school districts and airline passengers should anticipate travel delays due to snow, poor visibility and slippery conditions spanning early Tuesday morning into part of the afternoon rush hour.
Temperatures will dip to just below freezing by Tuesday morning and struggle to rise much during the day Tuesday.
Any areas that remain wet during the day Tuesday can become icy at night, unless treated.
While only a general coating to an inch of snow is forecast, where lake-effect snow persists there can be several inches.
In addition to some snow accompanying the passage of an arctic cold front, a band of lake-effect snow is likely to extend southward from Lake Huron, across Lake Erie and into western Pennsylvania, part of West Virginia and western Maryland Tuesday.
A sprawling storm will impact much of the region Tuesday, sending snow to Detroit just in time for the morning commute.
