Event narrative

Wind gust measured by a mobile mesonet platform.

Wider weather episode

Widespread daytime and evening thunderstorm activity impacted the WFO Norman Forecast Area on the 20th. This activity was influenced by two factors: 1.) a weak surface low and associated front, and 2.) a remnant mesoscale convective vortex (MCV) across the Red River Valley. Despite relatively weak wind shear across most of the area, slightly stronger daytime instability across the former regime promoted more robust convection (and associated severe outcomes). Damaging wind gusts and a few instances of large hail were observed with this activity.
