Overview
A strong low pressure system brought all kinds of weather conditions to the Great Lakes region and to Michigan on Tuesday, February 12th. Snow started to work in across the area from the Ohio border around midnight and continued to move north into the morning hours. Warmer air aloft also moved in from south to north and led to the development of a mix of precipitation across the region. Easterly winds gusting to around 25 mph during the morning fed plenty of cold Canadian air to the surface, allowing for freezing rain to dominate south of Detroit where tens of thousands of residents lost power. Sleet was more prevalent to the north. Eventually temperatures rose above freezing by the late morning, leading to a changeover to liquid rain. Precipitation tapered off across the region by early afternoon as the system's dry slot moved in.
