Marine Thunderstorm Wind · Gulf of Mexico

The Weatherflow mesonet at Bayou Bienvenue measured a thunderstorm wind gust of 49 knots or 57 mph.

Moisture rich air with near record precipitable water, for this time of year, surged north from the Gulf of Mexico across the local area as a warm front lifted northward. Increased lift from both the warm/moist airmass and front boundary primed the environment for robust updrafts. Mid and upper levels of the atmosphere began to cool as an upper level system approached the area. That combo of increasing instability and ample moisture resulted in a few severe storm over the local coastal waters.
