Severe Weather Threats Loom for Ohio and Tennessee Valleys

COLUMBUS, Ohio (WSYX) — A powerful storm system is expected to impact the Ohio and Tennessee valleys on April 21, bringing heavy rain, potential tornadoes, and severe weather conditions.

The National Weather Service warns that thunderstorms could produce frequent lightning, strong wind gusts, hail, and a minimal chance of tornadoes. Forecasters are particularly concerned about flash flooding, which has already caused significant disruptions in other parts of the country.

Over the weekend, storms ravaged the southern and Midwest United States, resulting in at least three fatalities in Oklahoma, including a 12-year-old boy. These storms also triggered flash floods that closed major highways. So far, more than a half-dozen tornadoes have been confirmed, including one that destroyed two homes in Marshall County, Oklahoma.

Flash flood warnings remain in place across a wide area from Kansas and Missouri to Kentucky, Arkansas, Mississippi, and Louisiana. As the storm system moves east, conditions are expected to weaken, but forecasters still predict risks of flooding and tornadoes in the incoming Ohio and Tennessee valleys.

On April 22, the storm will advance into the Mid-Atlantic region, bringing additional hazards such as wind gusts, hail, and a slight chance of tornadoes. Areas like Nebraska, Kansas, and Colorado may also face elevated fire weather conditions due to gusty winds and dry conditions.

Heavy rainfall is anticipated throughout the week across the Plains, which could lead to more flooding in areas already affected while providing relief to drought-stricken regions. Tristan Irish, lead storm warning meteorologist with AccuWeather, emphasized that this rainfall will be crucial for areas in need.
