Description:
An area of straight-line winds associated with a rear-flank downdraft (RFD) caused an area of damage that began in Canadian County and ended near Lake Hefner in Oklahoma County. The RFD damage path went from just west of Frisco Road between Southwest 29th Street and Southwest 15th Street in Yukon, across Route 4 and Reno Avenue, then across the Xerox Factory, continuing to near the south side of Lake Overholser where it crossed the county line. For the first two to four miles sporadic tree damage occurred. The damage then increased across the area as the storm moved further northeast. The damage path was up to two miles wide at times.
All of the tornadoes, nine total, that occurred on May 9, 2003 were produced by the same supercell. This thunderstorm developed in southwest Oklahoma along a retreating dryline. The storm moved northeast across Oklahoma eventually dissipating in northeastern Oklahoma. Most of the tornadoes occurred after dark. Three of the tornadoes affected western and northern portions of the Oklahoma City Metropolitan area making two days in a row (see May 8, 2003 data) that the Oklahoma City metro area was affected by a tornadic thunderstorm. The strongest tornado, an F3, moved across portions of the northeastern metro area. Large hail and strong straight-line winds associated with the rear-flank downdraft also occurred with this tornadic supercell. Other severe thunderstorms produced damaging large hail and strong winds across portions of Oklahoma.
