Central U.S.: Thunderstorms will bring hail and damaging winds in a narrow band from the upper Midwest to the southern Plains. Non-severe thunderstorms are also likely in the northern Plains.

Southern tier: Most of the southern U.S. all the way from the Southwest to the Southeast (except for Texas) will see clear skies and summerlike temperatures well into the 80s and 90s.
