Hail — Jefferson, Iowa

2021-06-22 · near Libertyville, Jefferson, Iowa

Wider weather episode

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 in central Iowa, but the high shear throughout eastern Iowa allowed for these storms to become organized and thrive in an environment with just enough of instability. Storms entered eastern Iowa around 3:00 PM CDT, producing up to golf ball 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.
