If tornadoes develop, they will most likely occur from near Des Moines to around Omaha. The biggest concern is large hail, with some storms likely to produce hail sizes greater than golf balls in Iowa and Nebraska. Strong wind gusts are a concern as well, especially later tonight.
A line of severe storms will be developing in Eastern Nebraska later this afternoon. It will sweep into Western Iowa this evening. Additional storms are likely to develop in Kansas and Northern Missouri.
The low pressure center and warm front will move to the east later tonight. Storms will spread into Southern Minnesota, Wisconsin, and Northern Missouri, and will continue across Iowa and Kansas.
The severe weather threat continues on Thursday and Friday. Areas from the Ohio Valley into the Southern Plains will have the risk to see severe thunderstorms.
