Winter Storm of April 13 - 16 

A very large and prolonged winter storm impacted the Northern Plains through the Upper Great Lakes Friday, April 13th through Monday, April 16th. There were two waves of heavy snow that impacted Upper Michigan--the first occurred late Friday into Saturday morning across far southern Menominee county and the second Sunday into Sunday evening across all of Upper Michigan. Storm total accumulations varied across the area through the weekend, generally from 6 to 12 inches, with most of that occurring Sunday and Sunday night. However, a few locations over the Michigamme Highlands of eastern Baraga and northern Marquette county and also across southern Menominee county (thanks to the first wave of snow that occurred there earlier in the weekend) saw storm totals  over 20 inches. The observer on the Hoist Basin north of Ishpeming reported a storm total of 2 feet. The storm also produced strong northeast winds on Lake Superior and Lake Michigan with wind speeds of 40 kts to 50 kts (46 mph to 58 mph) observed through the entire weekend. These strong winds resulted in high waves over 14 feet and some minor lakeshore flooding.  

We certainly weren't the only ones to experience this wide reaching storm. Blizzard conditions occurred over portions of the Dakotas and Minnesota, storm total snow accumulations reached a whopping 30 inches or more in some locations of northeast Wisconsin, and significant ice and snow occurred in portions of lower Michigan. We will provide links to neighboring NWS office stories on this storm.
