Episode Narrative Over the space of about four hours from late on April 19 into the early morning hours of April 20, 2011, a squall line brought a historic number of tornadoes to southern Indiana and central Kentucky. Storm surveys over the subsequent few days uncovered 25 tornadoes -the most ever recorded here in one outbreak. On the 19th, low pressure had organized over southeast Kansas with a stationary front reaching east into the central Appalachians. Plentiful moisture streamed northward from the Gulf of Mexico ahead of the system. The Kansas low moved along the front and swung a cold front eastward. Instability, strong upper level winds, and significant changes in wind speed and direction with height helped cause a large squall line to develop ahead of the low and its cold front. The squall line caused severe weather from the eastern Great Lakes to the Red River Valley. Over two dozen tornadoes spun up along the line as it crossed southern Indiana and central Kentucky. Despite the numerous twisters and the fact that they struck during the overnight hours, there were no fatalities or injuries.
Event Narrative An NWS storm survey confirmed an EF-1 tornado with wind speeds up to 100 mph. The tornado touched down at the intersection of West Batts Rd. and John Batt Road, where a grain bin was destroyed and several trees were blown over. Just southwest of the Mount Tabor Road/West Washington Road intersection the twister destroyed two silos and a 20ft x 30ft outbuilding. A single story house also suffered severe damage at that location. At the end of the damage path a house had its roof partially torn off and gravel from the driveway was lifted and pelted into the side of the house.
