What the reports say
Written by National Weather Service staff at the time of the event · public domain
On the evening of March 6, a squall line with damaging winds moved through the Johnson County Executive Airport, and produced significant damage to hangars and aircraft enclosed in the hangars. Several planes were flipped after the building shredded apart by the strong straight line winds. NWS survey inspected the site and due to damage being spread in a unidirectional fashion the cause of the damage was deemed to be straight line winds ranging between 80 and 90 mph.
Thunderstorm winds ripped off portions of a roof on a VFW building and a Toys "R" Us building. Numerous trees were uprooted. Tractor trailer rigs were overturned. Power lines were also downed and power poles were snapped in two. The downtown jail reported damage.
An isolated thunderstorm developed in very hot and humid air, and then collapsed, producing a 77 mph wind gust at Johnson County Executive Airport. The winds flipped two aircraft and moved several others at the airport.
