In addition to a morning complex of severe thunderstorms, a multi-modal severe weather outbreak impacted portions of northern and central Oklahoma during the evening of the 17th. Initial thunderstorm coverage during the morning across northern Oklahoma featured a few reports of thunderstorm wind damage/gusts. After quickly moving eastward, allowing for substantial airmass recovery across the area, additional severe thunderstorms developed ahead of an approaching synoptic wave by the early evening. Initial thunderstorms impacted the Oklahoma/Kansas border areas of Kay County, producing a few reports of large hail. All the while, an intense supercell thunderstorm was drifting from the northeastern Texas Panhandle into portions of western Oklahoma. This storm became tornadic as it crossed into Ellis and Roger Mills County, producing a significant (EF-2) tornado here. As this thunderstorm grew upscale, along with additional development to its north, an organized mesoscale convective system (MCS) took shape. Numerous reports of wind damage and three brief tornadoes occurred as this system swept eastward across the northern one-half of the forecast area.
