Severe high precipitation supercells developed across north central
Texas the evening of May 8th and moved slowly eastward just south of the Red River during the pre dawn hours of May 9th.  These storms
encountered a strong capping inversion as they moved east which resulted in these storms collapsing before they moved into northeast Texas.  However, one storm collapsed and produced a heat burst in Red River County Texas.  As the storm collapsed, it produced damaging wind gusts across the western portions of the county.  The temperature at
Clarksville, Texas jumped nearly 8 degrees when the winds began
increasing from the west with the collapse of the storm.
By the afternoon of May 9th, the atmosphere became very unstable across
the region and storms produced large hail and damaging thunderstorm wind
gusts across northeast Texas, southeast Oklahoma and southwest Arkansas. Locally heavy rainfall also produced flash flooding across much of the region as well.
