Overview

An intense storm system tracked across the state of Iowa on Friday, March 31st. This system pulled unseasonably warm and moist conditions into the Midwest, which coupled with a very favorable wind profile, and created quite the volatile environment for severe thunderstorms. This produced several long lived supercells which developed across central Iowa during the afternoon.  The storms were prolific hail producers along with a few reports of wind damage as they moved rapidly northeast.  Eventually, the storms produced a few tornadoes before exiting into eastern Iowa.
