2007 Groundhog Day tornado outbreak

The 2007 Groundhog Day tornado outbreak was a localized, but devastating tornado event that took place in central Florida early on February 2, 2007. Early morning temperatures had risen well above average for the season, which, combined with increased moisture and a powerful jet stream, created enough instability and wind shear for thunderstorms to rotate and spawn tornadoes. Due to the conditions, a long-tracked supercell formed and produced three tornadoes during a one hour and 17 minute time frame. The supercell resulted in a 70 mile (110 km) trail of damage.
