Overview

Logan and Washington counties

Several tornadoes along with large hail occurred across portions of Logan and Washington counties on June 21, 2023.  After thorough analysis of videos, chaser and spotter reports, up to 37 tornadoes occurred.  Most of these were weak and short lived (under a minute), however, a few did attain EF2 intensity and were of longer duration over portions of Washington county.   Fortunately, most of these were over open areas, with just a few locations experiencing damage.  27 of the tornadoes were produced by one slow moving supercell thunderstorm over Washington county.  
 

Red Rocks Amphitheater

A severe thunderstorm with 2" hail struck Red Rocks Amphitheater around 9:20 PM MDT that same evening.  The hail injured nearly 100 concert-goers, with many requiring hospitalization.  This was one of the worst hailstorms in Colorado regarding human injuries in a long time.  There is a radar loop of that storm, along with NWS warnings, available on the radar tab.
