The largest number of deaths, 12, were in Missouri, mostly in Wayne County. Eight deaths were reported in Kansas after a 50-vehicle collision during a "severe dust storm," and six deaths were reported in Mississippi following multiple reported tornadoes.

At least 30 people died as violent weather swept the country on Friday and Saturday, and the threat isn't over.

A new tornado watch was issued Sunday for portions of West Virginia, Ohio and Pennsylvania. The severe weather threat will be ramping up across this region over the next few hours, according to the National Weather Service.
