Central US to continue to face flood risk as calendar turns from July to August

AccuWeather logo AccuWeather 5 days ago Ryan Adamson

After rain fell in portions of South Dakota and Nebraska on Wednesday and Thursday, those areas will have drier conditions on Friday. However, heavy rain with the potential for flooding will continue farther east and linger into the start of the weekend.

"The heaviest rainfall will gradually shift eastward on Friday and Saturday into the Ohio Valley as well as Tennessee, northern Mississippi, northern Alabama, Kentucky, western North Carolina and West Virginia," said AccuWeather Senior Meteorologist Dan Pydynowski. "Through Saturday evening, a widespread 2-4 inches of rainfall with an AccuWeather Local StormMax™ of 6 inches can fall."

Cities such as St. Louis, Nashville, Tennessee, and Louisville, Kentucky, have already had rounds of heavy rainfall this week. Therefore, any floodwaters may be slow to recede, and renewed flooding will also be possible.


"Those out driving across the region should be on the lookout for water-covered roadways and always remember never to drive through floodwaters," Pydynowski said.

Drivers on stretches of interstates 40, 44, 55 and 70 could face not only the water-covered roadways that Pydynowski mentioned but also reductions in visibility due to the intensity of the rain. In addition to avoiding flooded roadways, slowing down is also advised to reduce the risk of hydroplaning on wet pavement.

Gusty thunderstorms will also be possible, but heavy rainfall will be the main concern. With the ground saturated due to the heavy rain, even winds that are not overly strong can cause trees to topple.

Rain is likely to shift farther north for the second half of the weekend. However, the rain will move away much more quickly, and the precipitation will even be beneficial in some areas.

"The heaviest rain will likely shift northward by Sunday into parts of the Lower Peninsula of Michigan, northern Indiana and northern Ohio," Pydynowski said. "Some of these areas have been experiencing a slight to moderate drought, so the rainfall would be welcome," he noted.

While the risk of showers and thunderstorms will return in some of the hard-hit areas next week, any rainfall is likely to be neither as heavy nor as long-lasting.
