What the National Weather Service wrote

The McKinnon Airfield ASOS measured a wind gust of 46 mph.

The wider storm

A frontal zone was north of the area with high pressure extending across south Florida. Aloft, a 500 mb trough base was across the area. Waves of PVA moved eastward through the base of the upper trough which enhanced diurnally driven convection along the sea breezes under westerly steering flow.

Began near Mckinnon Arpt (31.1500, -81.3800).
