More than 300 reports of severe weather were recorded Sunday from Oklahoma to Wisconsin. Hail the size of grapefruits, hurricane force wind gusts and 24 tornadoes were reported, as a slow-moving front fired up showers and thunderstorms into the nighttime hours. 

An EF1 tornado with winds of up to 110mph was confirmed just outside of Wichita, KS., and National Weather Service survey crews continue to survey the damage and estimate the strength of the reported tornadoes.

The same slow-moving storm system can spawn more severe weather Monday and Tuesday from Texas to the Great Lakes, possibly impacting some of the same areas already devastated. By Wednesday, the system could bring isolated severe thunderstorms along the Ohio Valley and interior Northeast.

Since some areas from Oklahoma to Wisconsin will see several rounds of storms, flash flooding will be a concern, as the ground is already saturated from heavy rain over the weekend.

The National Weather Service was forecasting more of the same for the region — including Oklahoma City and Tulsa — Monday afternoon and evening, warning of the possibility of tornadoes and baseball-sized hail. Residents of Arkansas, Kansas and Missouri were also warned to watch for bad weather Monday.

Oklahoma Gov. Mary Fallin began touring the hardest-hit areas early Monday, including Carney, in Lincoln County, and a mobile home park near Shawnee, 35 miles southeast of Oklahoma City, that suffered a direct hit and where the tornadoes claimed two lives.
