California Severe Weather Outbreak

March 23, 2002

Throughout the afternoon of March 23, 2002, thunderstorms broke out all over the Sacramento and northern San Joaquin Valleys of California. Many of these storms produced hail, and there was even a report of a tornado near Williams. Of particular interest was one supercell that remained nearly stationary over southeast Glenn and southwest Butte Counties late in the afternoon. Although no tornadoes were confirmed out of this cell as of this writing, a tornado warning was issued for this supercell for over an hour. Following are some base reflectivity images of this cell from the WSR-88Ds at Beale AFB and at Davis (all images courtesy of the National Weather Service)....
