Overview

|
Showers and thunderstorms developed late in the day on Aug 27th in northeast Missouri and spread into southeast Iowa and far western Illinois into the evening. Large hail fell for nearly one half hour straight in Rutledge, MO, including as large as golf ball size. A pronounced downburst (sudden rush of wind under and near a thunderstorm) caused widespread damage in Burlington, IA knocking down trees, limbs, and powerlines. Five homes had holes in the roofs due to falling limbs. A commercial storage building had a partial roof collapse and another large tall outbuilding had partial roofing peeled back, consistent with wind estimates of 70 to 80 MPH. Rainfall totals of 2 to 4 inches were observed in parts of northeast Missouri and southeast Iowa. Oppressive heat and humidity that began on the 26th and persisted into the 27th helped spawn these storms. Both Dubuque (tied) and Moline (exceeded) daily record highs on the 27th, with Moline reaching 98° and Dubuque 94°.
