EF0 tornado in Graves County, Kentucky

This weak tornado formed along the Tennessee state line, then tracked northeast across the southeast corner of Graves County. It passed through farmland and wooded areas. Many trees were snapped or uprooted. There was minor damage to barn roofs. Peak winds were estimated near 75 mph. The tornado continued into Calloway County.

Isolated severe thunderstorms developed across western Kentucky during the evening hours. The storms developed ahead of a cold front in a destabilizing air mass characterized by dew points in the lower to mid 60's. The supercell storms awaited the approach of a mid-level impulse from Oklahoma, which was downstream from the primary shortwave trough over the Plains. A southwesterly low-level jet increased substantially during the evening. A couple of tornadoes were produced in southwest Kentucky, along with a few reports of hail and damaging wind. Outside of the thunderstorm activity, some of the southwest winds aloft mixed down to the surface in the form of gusts from 40 to 50 mph, and an isolated gradient wind gust to 65 mph was measured on a hill near Calvert City in Marshall County.
