Overview
A few pockets of snow, sleet, and freezing rain tracked across the region early Sunday evening. A larger area of a wintry mix of precipitation then overspread the area later Sunday evening into the overnight hours early Monday morning. The wintry mix eventually changed over to snow from northwest to southeast. Snowfall accumulations ranged from less than an inch up to 3 inches, with the greatest totals across far northeast Indiana, far northwest Ohio, and south central Lower Michigan. A light glaze of ice accumulation was also reported that led to hazardous travel conditions from late Sunday night through the Monday morning commute.

Environment
Strong southwest flow in the lower levels of the atmosphere allowed a warm layer aloft to be maintained through the evening hours on Sunday. This warm layer aloft allowed precipitation to melt in this layer and then refreeze at the surface resulting in the very slick and hazardous roadwdays.
