Significant Heavy Rainfall Expected Across South Florida Today; Severe Weather Possible in the Midwest

A High Risk (level 4 of 4) of Excessive Rainfall is in effect for portions of South Florida today. Rainfall rates between 2-5 inches per hour will likely lead to considerable flash and urban flooding. Across the Midwest, scattered severe thunderstorms capable of producing very large hail, severe wind gusts and tornadoes are possible this afternoon into the early evening hours. Read More >

Overview

Multiple rounds of storms moved through the Upper Mississippi River Valley on Tuesday, May 21st. During the morning hours, non-severe storms produced heavy rainfall and frequent lightning. By early afternoon there was a lull in precipitation that helped the atmosphere recover and reenergize ahead of a fast-moving line of severe storms moving across Iowa.

The line of severe storms moved into southeast Minnesota and northeast Iowa between 4-5 p.m. and produced widespread wind damage and over 10 tornadoes as they marched northeast across the area. Tree damage and power outages were plentiful with some structures damaged as well. A few storms also produced large hail.
