Event narrative

The AWOS KOYE measured a thunderstorm wind gust of 40 mph or 35 knots.

Wider weather episode

A deep upper level trough over the southwest US was very slowly moving east on May 6th. At the same time, a ridge of high pressure was centered over Central America. This creased a split flow pattern between those 2 features which increases buoyancy. As a previously stalled boundary in the northern Gulf lifted north as a warm front. High instability created by this environment supported severe wind gusts over local marine areas.
