A rainy Thursday night is already causing flooding in some parts of Ohio. Columbus, and the state, is in for even more rain this weekend.

We've seen a relentless surge of severe thunderstorms, tornadoes, and flooding rain for over a week now in the Midwest and South. Fortunately, there's light at the end of this tunnel. Here's when quieter weather will arrive and how long it may last.

“A lot of flooded basements, sump pump failures,” James Blankenship with Mr Rooter Plumber said. Blankenship has worked in plumbing for more than a decade in Dayton. He says homeowners need to be ready for the rain moving toward the area.

Saturday is the day of greater concern. First, the risk for severe weather increases but it's also the day that we'll see our heaviest rainfall. Because creeks, streams and rivers are already high, this is the day that flash flooding is of greatest concern.
