A strong low pressure system developed over the southern Plains during the the day on the 24th. During the evening of the 24th and through the early morning hours of the 25th, the low moved northeast into central Wisconsin. Warm, moist air surged northward into the northern Great Lakes Region ahead of this storm system. This allowed for widespread rainfall to develop across the Great Lakes. Surface temperatures across northern Lower and eastern Upper Michigan, however, remained below freezing throughout much of the period. This set the stage for freezing rain. Across northern Lower Michigan, the freezing rain began during the evening of the 24th. By late in the evening, a quarter of an inch of ice had accumulated on exposed surfaces. Across eastern Upper Michigan, the freezing rain began late in the evening on the 24th, and continued through the early morning hours of the 25th. By the morning of the 25th, ice had accumulated to between and a quarter and a half inch on exposed surfaces. As the storm system moved northeast across Wisconsin during the morning of the 25th, a surface warm front moved north across Northern Michigan. This quickly allowed surface temperatures to rise well above freezing, thereby rapidly melting the ice on the trees. Widespread tree damage and power outages did not occur with this event, as most trees and power lines were able to sustain the weight of the ice until it melted. Many area roads, however, were extremely icy.
