The wider storm
Significant severe storms on the afternoon and evening of April 14th brought numerous reports of large hail, damaging wind, and multiple tornadoes. The U.S. Hwy 20 corridor saw a long lived supercell that producing large hail (up to baseball size), damaging wind (88 mph gust at the Dubuque Airport), and several tornadoes. Additional storms developed further south between I-80 and Hwy 20 that brought large hail and a photogenic tornado near Onslow, IA.
More storms quickly followed overnight and again on the next day, April 15th, bringing heavy rain, large hail, and isolated wind damage. Rainfall amounts over 1.5 were common north of I-80, with the highest totals over 3.5 seen in northwest IL. This caused a mudslide on Hwy 84 in Carroll County closing the road for an extended period of time.
Began near (dbq)dubuque Muni Ar (42.4200, -90.7400).
