Overview
Significant severe storms Tuesday afternoon and evening 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 on Wednesday, bringing heavy rain, large hail, and possibly a tornado near the Louisa/Muscatine county line. 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.
More details will be made available in the coming week to this page for these 2 weather events. A possible tornado near Letts, IA near the Muscatine and Louisa County borders has been surveyed and is still being evaluated.
