Severe thunderstorms are in the offing on Saturday over part of the central Plains and middle Mississippi Valley.
The storms will erupt in parts of northern Oklahoma to eastern Kansas, much of Missouri, southern Iowa and western Illinois. Most of the storms will occur between 2:00 p.m. and 10:00 p.m. CDT, but some of the storms can survive through Saturday night.
The strongest storms will bring damaging wind gusts, large hail, flash flooding, frequent lightning strikes and the risk of a couple of tornadoes to some communities.
Major cities that could be hit by the storms include Topeka, Kansas; Tulsa, Oklahoma; Joplin, Springfield, Kansas City and St. Louis, Missouri, Springfield, Illinois; and Cedar Rapids and Ottumwa, Iowa.
In addition to foiling outdoor plans like ballgames, weddings and graduations, the storms can knock out power in some communities, disrupt travel along I-35, I-44, I-49, and I-75, cause property damage and even threaten lives.
Elsewhere, locally drenching downpours will bring the risk of flash and urban flooding on Saturday into Saturday evening from parts of the central Appalachians, the Ohio Valley and the mid-Atlantic to the central Gulf coast.
More widespread severe weather and the potential for tornadoes is forecast on Mother's Day from central Texas, Oklahoma, central and eastern Kansas, northwestern Missouri, southeastern Iowa and central and northern Illinois.
