Severe Weather February 20, 2014

Surface Map at 7:00 PM Feb. 20

A potent area of low pressure pushed a strong cold front across central Indiana during the evening of February 20. Ahead of the front, very warm and moist air surged north. This melted much of the snow cover across the area, resulting in some flooding. The rain that accompanied the front led to additional flooding problems. A line of severe thunderstorms along the front brought damaging winds to many areas, along with some large hail at a few locations. A brief tornado touched down in Rush County, and another tornado touched down in Montgomery County. Details of the tornadoes are below. At the bottom of this page is a list of reports received from this event.

The tornado started 2.5 miles southeast of Crawfordsville and ended 0.7 miles  south of Darlington. Numerous outbuildings were damaged, and numerous homes lost shingles. A truck canopy was partially blown off. Numerous trees were sheared off halfway or more above ground.

The line of severe thunderstorms took on a bowed structure as it entered northwest Rush County on Friday evening.  Numerous areas of severe, straight-line wind damage were observed near the Arlington area.  However, one homestead east of County Road 700 West on County Road 300 North did exhibit signs of damage that appeared tornadic. A few trees were downed, with one blown through the back side of a tin shed.  Also, the roof was removed from an outbuilding on the premises.
