EF1 tornado in White County, Indiana

A survey of damage in northeastern White county revealed damage consistent with a brief EF1 touchdown. The tornado touched down in an open field northeast of the intersection of County Road 400 North and 1350 East before flipping 4 sections of a center pivot irrigation system. As the tornado moved northeast a trailer was impacted removing the roof and taking down half of the walls (DI: MHSW DOD: 4). A woman was in the trailer home at the time it hit but made it to the bathroom as it was falling apart and survived with no injury. Debris from the trailer was thrown north and northwest into an adjacent field. The tornado continued northeast into a grove of trees where it continued less than 50 feet before lifting one quarter mile southwest of the intersection of County Roads 500 North and 1450 East. The maximum wind speed is estimated at 100 mph.

Deep low pressure moved across the northern Great Lakes, with a strong cold front trailing well south into Arkansas. A 50 to 60 knot low level jet aided in advecting in dewpoints greater than 60 degrees. 0-1km storm relative helicity values of 400 to 600 m2/s2 setup the perfect environment for individual thunderstorms to rapidly rotate. Numerous circulations were noted during the event, some significant, which produced swaths of wind damage as well as several weak to strong tornadoes. Given forward speed of 60 mph or more, the convection quickly translated across the area in a matter of hours.
