Event narrative

NDBC buoy 42040 measured a thunderstorm wind gust of 37 kts or 42 mph.

Wider weather episode

Interestingly, the initiation of this event started on the afternoon of August 1st near the Oklahoma Panhandle. An Mesoscale Convective System first developed and intensified as it tracked across Oklahoma during the overnight hours. This feature steadily weakened after sunrise on August 2nd and began traveling southeast into northern Louisiana during the daytime hours. Even though convection had dissipated by the time the leading edge of the system reached the coastal waters, the strong buoyancy created by the low pressure boundary and Gulf water temperatures over 90 degrees sparked robust thunderstorm development. One storm passed over buoy 42040 and produced a severe wind gust.
