Event Summary: April 23rd-24th, 2026

Overview

A line of very gradually fading storms produced surges of straight-line wind damage. These were most pronounced to the immediate south of mesovortices (small scale circulations within the thunderstorm line that can in themselves result in tornadoes). Based on the nature of damage, observations, and radar, these reflect 65-80 mph wind gusts.

Two main areas of damage that we believe to be due to such enhanced wind surges were: 1.) Kalona, IA (Washington Co) and 2.) the east-southeast side of Iowa City (Johnson County).

A third area of isolated wind damage from Miles to Sabula, IA (Jackson County) was a little different in that it was much more of an outflow surging from decaying storms, but again straight-line winds.
