Severe thunderstorms developed in the morning, and again in the
afternoon, on Tuesday, 21 June 2011. The thunderstorms formed after
several days of record setting hot weather, which was the result of a
persistent ridge of high pressure in the middle and upper atmosphere.
On 21 June 2011 a strong trough developed in the middle and upper levels
of the atmosphere moved from west to east across the central Plains
breaking down the upper level ridge over the Four State area. This
strong upper level trough allowed for gusty south winds to occur at the
surface of the atmosphere in the four State area, and brought enough
lift and instability to the atmosphere to allow scattered severe
thunderstorms to develop both in the morning and the afternoon of 21
June 2011. These thunderstorms produced wind damage and a few
tornadoes, in addition to brief episodes of heavy rainfall.
