Overview

An environment favorable for intense thunderstorm development was in place across the area on Thursday, June 4th. While fairly isolated, thunderstorms that did become established produced a large degree of damage, most notably from Brown County east-southeastward through Deuel County and beyond. Measured wind gusts ranged from 50 to 95 mph, with even greater wind speeds likely at some locations. While damage was caused by straight-line winds (meaning no rotation), the wind speeds alone would fall into an EF1 tornado category.  Downed power lines, uprooted trees, and even structural damage was reported in the wake of this storm as a result.  Image
