Overview

Temperatures in the 90s and high moisture in the low levels led to diurnally driven thunderstorms on Friday, June 11th. Weak upper level support kept these storms relatively isolated and short-lived. Another focus area for convection was along a remnant outflow boundary from an MCS that morning, which led to some further storm development later in the day. One storm reached severe limits, which was seen in Burlington, Iowa. This storm resulted in strong winds, over 50 mph, that lead to multiple damaged trees and some buildings damaged.
