Wider weather episode

A slow-moving mesoscale convective vortex (MCV) produced severe weather and flash flooding during the morning and afternoon of the 26th. An initial complex of thunderstorms across southwestern Oklahoma and western-north Texas produced reports of thunderstorm wind damage and large hail, especially with a supercell thunderstorm that moved near the city of Lawton. Areas of persistent heavy rainfall also led to flash flooding across this area, with a flood-related fatality occurring in Lawton as a motorist drove into flooding beneath an underpass. By the afternoon, as the broader convective vortex moved eastward and instability developed, additional thunderstorms developed across southeastern Oklahoma. A few of these thunderstorms, exhibiting brief supercellular characteristics, produced hail and a tornado as they interacted with a remanent surface boundary across the area.
