Thunderstorm Wind in Union County, Florida

Trees were blown down across SW 111th Street and SW 51st Trail.

Strong to severe thunderstorms formed along a prefrontal trough in the evening which was driven by a potent mid level shortwave trough that slowly rotated across the Deep South through the following day. At the surface, a cyclone deepened as it tracked into the Tennessee/Ohio valleys during the evening and it resulted in a strengthening

low level wind field including a strong LLJ (around 50 kts) that lifted across the interior portions of SE GA with the core of the jet skirting just northwest of SE GA. As the LLJ

strengthened, an ongoing quasi-linear complex of storms pushed into SE GA along a SW-NE oriented prefrontal trough. Instability (1500-2000 j/kg) and shear (150-200 m2/s2) supported of all modes of severe weather (damaging wind, hail, and isolated tornadoes) as activity propagated into SE GA and portions of NE FL into the evening.
