Severe thunderstorms with large hail, damaging winds and tornadoes are quite likely across the Central U.S. today through tonight.
A severe weather outbreak is possible for the Central US today through tonightt. There are still some uncertainties as to its extent. However, if various weather features that aid in the development of severe thunderstorms, namely: Shear, Lift, Instability and Moisture [SLIM], come together in time and place, then very large and destructive hail (near or larger than softball size, i.e., > 3" in diameter), damaging wind gusts and strong, possible long-track tornadoes,could occur across the central US.
The greatest tornado threat probabilities are from south central Nebraska, south across Kansas, Oklahoma into extreme north Texas. Major metro areas included in this zone: Grand Island and Hastings in Nebraska; Salina, Wichita and Emporia, Kansas; Oklahoma City, Norman and Edmond, Oklahoma.
Another wave of severe weather is also possible across the Southern Plains east to the Lower Mississippi Valley this Thursday through Saturday.
