Event narrative

A tree was blown down in Wellborn.

Wider weather episode

A prefrontal squall line passed across northeast Florida during the afternoon and early evening hours. A few bowing segments developed within the broader line of thunderstorms and one of these features generated a brief tornado as it tracked east-southeastward around 30 MPH across the Starke FL area. A Severe Thunderstorm Warning was issued for the area with potential for brief and isolated tornadoes.

The synoptic environment had strong shear, but an inversion near 500 mb limited updraft stretching and kept convection relatively shallow as the squall line moved across the area. During the late afternoon, a bowing segment coincided with a nose of low level moisture (dew pt rose to near 70 deg) as the convection moved east across Bradford county near Starke. This is where there was enough low level instability and shear to support a mesovortex tornado along the leading edge of the bow.
