EF1 tornado in Richland County, Ohio

The tornado began at a farmstead along Possum Run Road, near the intersection with Snyder Road, and destroyed an outbuilding. As the tornado moved east-southeastward, it produced extensive tree damage before entering Ashland County. Estimated peak tornadic winds were 105 mph.

A surface front moved little during the evening of the 13th through predawn hours on the morning of the 14th. The front remained draped southeastward from far-southwest Lower MI and far-northeast IN, through northern OH, and into southwest PA. This front separated a very warm, humid, and unstable air mass to its southwest from a cooler, drier, and stable air mass to its northeast. Two mesoscale convective systems (i.e. MCS's) developed and evolved southeastward along this front.

During the late evening of the 13th through first hour of the 14th, the first bowing MCS evolved southeastward across portions of northern OH and generated widespread damaging to destructive wind gusts and three QLCS tornadoes. This MCS was a true derecho. The second bowing MCS evolved southeastward across portions of northern OH and generated sporadic damaging wind gusts during the wee hours on the morning of the 14th. Both MCS's occurred along a tight northeast-to-southwest gradient in MUCAPE accompanying the front and amidst primarily moderate to strong MUCAPE. The two MCS's also took advantage of moderate DCAPE and moderate to strong effective bulk shear.
