Winter Storm in Michigan, April 1, 2023

April 1, 2023 · NWS APX · 5 events in 5 counties and zones

A strong trough quickly progressed from the Great Plains over the Great Lakes/Ohio Valley 3/31 into 4/1, producing strong ascent aloft to provide support for a 990mb cyclone to trek across northern Michigan during that time. While much of the area saw heavy rainfall totaling over 1, sufficiently cold temperatures were in place across the eastern upper peninsula for heavy snowfall.
