June 9th 2013 Tornado Path near Lowmansville, KY
On June 9th 2013 thunderstorms moved across eastern Kentucky behind a synoptic scale stationary front that extended from Illinois through Ohio and into West Virginia. There was a less definable mesoscale warm front that extended from northern Kentucky through southern West Virginia, creating increased convergence and instability in eastern Kentucky. The tornado was on the ground for approximately .5mi before it lifted and the supercell moved left, occluded and gusted out, which resulted in thunderstorm wind damagenear Ulysses, KY.
With convergence at the surface (above) and divergent 40kt-50kt flow at 250mb (image below) the increased potential for some isolated severe thunderstorms evolved throughout the day.
Although eastern Kentucky became increasingly more unstable as the day progressed, conditions were not ideal for tornadogenesis. In fact, as of 4pm EDT, The Storm Prediction Center had Lowmansville, KY outside the Slight Risk area for tornadoes, severe wind or hail.
By 4:32pm EDT thunderstorms had become intense enough for our neighbors at the Jackson, KY WFO to issue a Severe Thunderstorm Warning:
