Warmer temperatures will be welcomed across Ohio, but it may come at a cost.

Snow on the ground has the liquid equivalent of 1 to 2 inches of rain. Add to that showers and thunderstorms on Thursday that could dump 1 to 1.5 inches of rain and it could cause flooding problems.

"I think we've got snow cover everywhere and the rain is also going to be crossing the whole state so the concerns are going to be just about everywhere," said Brian Coniglio, a meteorologist at the National Weather Service in Wilmington.

With frozen ground, any water that does hit the surface won't get absorbed into the soil, but run right into ditches, creeks, and rivers.

"We're going to have to just kind of monitor the forecast and take action if you're in a flood-prone area," Coniglio said.

He expects minor flooding in areas that normally see high water, but says the severity will depend on how much rain falls later this week.

River flooding could be a concern over the weekend.
