Local Weather History For July 28th...
Beginning on July 28, 2004, heavy rain produced flash flooding across
western north Texas and south-central Oklahoma. After 48 hours, up to
8 inches of rain had been measured in Archer and Knox counties, with
nearly 5 inches across Wichita and Clay counties. Runoff caused
several rivers to spill their banks, including the South Wichita
River, which eventually crested nearly 5 feet above flood stage near
Benjamin, the 3rd highest crest on record for that site. Ardmore
received nearly 5 inches of rain as well, along with flash flooding
at the Chickasaw National Recreation Center.
