More severe weather will rattle the central U.S. on Thursday, while the heat will be on high in much of the Southwest, Southeast and mid-Atlantic.
East, South: High humidity and summerlike heat well into the 80s and 90s will cook the Deep South, Southeast and mid-Atlantic on Thursday. Light showers and cooler temperatures will keep a springlike feel in the Northeast and New England.
Central U.S.: A large chunk of the central U.S. will be under the gun for severe thunderstorms Thursday, all the way from the Upper Midwest to the southern Plains. Big hail, damaging winds and a few tornadoes are all possible.
West: Spring snow will whiten much of the northern Rockies and parts of South Dakota where up to 6 inches is likely. Other than some coastal rainshowers in coastal sections of Washington, Oregon and northern California, the rest of the West will be dry and warm.
