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.
