Pacific moisture will continue to bring locally heavy coastal/lower elevation rain and heavy mountain snow to the West Coast and portions of the Intermountain West through Monday. A wintry mix will create hazardous travel across the northern Plains and Upper Midwest into early Monday. Dry, gusty winds are resulting in elevated to critical fire weather in the south/central High Plains. Read More >

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.
