Strong thunderstorms will continue this evening over parts of southwestern Oklahoma and western parts of northern Texas. Isolated thunderstorms also will continue over parts of northwestern Oklahoma. Hail and strong damaging winds will be possible before the storms weaken quickly by nightfall. Radar at 745 PM indicated strong thunderstorms northwest of Mangum… just east of Hollis… and in northwestern Texas between Childress and Quanah. The storms extended southwestward through West Texas to between Midland and Abilene. Individual storms were moving east northeast at 15 mph. An isolated thunderstorm also was located over northwestern Oklahoma between Buffalo and Freedom. This storm was moving northeast at 20 mph. Further development will be possible through sunset… but the existing storms are likely to begin weakening after sunset with the loss of daytime heating. Conditions are such that any storms will remain capable of producing strong and possibly damaging surface winds… even as they weaken and collapse. The storms should dissipate by nightfall.
