Thunderstorm Wind in Spencer County, Kentucky

One tree was reported down with water over the roadway in an area that typically floods.

Large scale lift and moisture transport were in place beneath the right entrance region of an upper level jet situated between a central U.S. trough and an Atlantic Coast ridge. A former tropical low coupled with and rode the upper level flow northeast along a cold front that was draped across the middle and lower Mississippi River Valley. This strengthened a surface wave that moved through the Ohio River Valley region that caused a response in the low level jet, resulting in an increase in precipitation coverage and intensity. The intensified storms produced areas of gusty winds and a single tornado in Hardin County, Kentucky.
