Overview

 

A few severe thunderstorms developed across eastern Iowa and far northeast Missouri on Tuesday, June 22, leading to several reports of severe hail and some wind damage. This was a day in which the instability was greater in our western counties, but the high shear throughout our forecast area allowed for these storms to become organized and thrive in an environment with just enough of instability. Storms entered our area around 3:00 PM CDT, producing up to golfball sized hail.  A couple of these storms were long-lived, traveling through a few counties before dying. Some damaging wind gusts were also noted in Buchanan County, where large tree limbs were snapped and a power pole was blown down.
