Wider weather episode

A pre-frontal cluster of showers with isolated thunderstorms tracked northeast across north Florida during the afternoon and evening.

A progressive upper level trough over the central U.S. moved east as the lead short wave trough lifted northeast across the Ohio Valley during the day. Well ahead of a cold front, Northeast Florida and Southeast Ga were located in the warm sector of this system with a strongly sheared atmosphere. The 12z and 00z JAX Upper Air Sounding showed 0-3KM helicity values between 300-400 m2/s2. Surface based instability was weak but enough for thunderstorm activity over mainly northeast Florida. Two thunderstorms merged together as thunderstorms tracked from the nature coast across the Florida peninsula over Flagler County. The role of the storms interaction and merger most likely assisted in the subsequent storm enhancement and tornado genesis across Palm Coast, Florida. The storm strengthened with 40 knots of rotational velocity around 5.7 kft over Palm Coast in Flagler county, and a tornado warning was issued at 6:54 pm EST. The first confirmed tornado touchdown damage was recieved at 7 pm that nigth in Palm Coast. There were no injuries nor fatalities reported.
