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 90 mph. The tornado started in Sunset Trailer Park where about two dozen trailers were damaged. Several trailers were moved off of their foundations and had roof damage. One trailer's roof was thrown 65 yards. Trees and power lines were damaged as well. The tornado then weakened slightly to 80 mph as it moved northeast into a subdivision damaging several small trees, sheds, and roofs. A trampoline was thrown and wrapped around a shed and a tree. More tornado damage was then found at the end of a subdivision right behind a church off of Holmans Lane. The south side of the church was completely blown out. Sheds were destroyed and trees uprooted. Insulation was thrown from north to southeast. Across Holmans Lane tree and shingle damage was found. The path ended near Indiana 62.
