Flood threat for Ark., Tenn., Ky., Ohio, even Texas

Heavy rain could bring flooding to parts of Arkansas, Tennessee, Kentucky, Ohio and even drought-stricken Texas Sunday and Monday, The Weather Channel warned.

In a posting on its website, Chris Dolce, a meteorologist at The Weather Channel, said some 1 to 3 inches of rain was expected across a swath of the central U.S., from Texas to Ohio, where the ground was already saturated with water.

However, up to 6 or more inches are possible in some parts, he warned.

"Excessive rains over saturated soils are not a good combination. As a result, we are looking at a flood threat Sunday into Monday," in the affected areas, Dolce said.

"Flood watches have been issued for portions of the region, including the Little Rock, Ark., Memphis, Tenn., and Paducah, Ky. metro areas," he added. In an update to the posting, Dolce said there was also a flood watch for Cincinnati, Ohio.

Some 83 percent of Texas is still affected by an extreme drought, the second worst category.

However, Dolce said the weather front "has the potential to dump an inch or more of much needed rain in portions of the eastern and central Texas."

"The swath of heavy rain also covers adjacent areas of northwest Louisiana, which could also use significant rains due to the prolonged drought. That said, too much rain too quickly could cause some flooding even in drought areas," he cautioned. "This is a case of potentially receiving too much rain to fast."

A band of snow affecting the Midwest was lingering in parts of Wisconsin and Michigan early Sunday, but it was expected to diminish during the morning, The Weather Channel also reported.
