This radar imagery was taken from the WSR-88D network in Fort Worth TX (KFWS) at 546 pm CDT on April 26, 2011. The radar reflectivity shows the supercell thunderstorms centered southeast of Canton and south of Interstate 20. The white and darkest purple colors represent hail falling from the storm. The hook echo, which is often an indication of very strong low level rotation, appears to have wrapped counterclockwise back onto itself.

The storm relative radial velocity image depicts the tornadic circulation as the bright red colors (motion away from radar) adjacent to bright green colors (motion toward the radar). The KFWS radar is about 90 miles west of the storm. The strong radar circulation at
546 pm CDT was 6.7 miles southwest of Van and was moving to the east northeast.
