Thunderstorm Wind — Morrison, Minnesota

2023-07-22 · near Cushing, Morrison, Minnesota

Event narrative

Delayed report of multiple trees down with damage to roofs on southeast side of Lake Alexander.

Wider weather episode

A subltle shortwave trough within northwest flow moved across the region and provided enought lift for scattered afternoon thunderstorms. There was sufficient MLCAPE (1500 J/kg) and Effective Shear (30kts) for some stronger updrafts that produced severe hail and damaging wind gusts. Overall these storms were relatively short lived and died off once the outflow undercut the updraft.

Of particular note, in Elk River a tree feel on a tent where there was a birthday party ongoing. There were 3 minor injuries.
