Large swaths of the central U.S. were bracing for severe weather Wednesday after at least 23 people were injured Tuesday evening when a tornado hit central Texas.

The lower Mississippi Valley, the Midwest and lower Ohio Valley all faced a threat of tornadoes and severe thunderstorms, according to the National Weather Service

The storms are likely to be accompanied by damaging winds and “very large hail” up to baseball size, the weather service said. A tornado watch was issued for several states Wednesday afternoon, including parts of Arkansas, Louisiana, Texas, Missouri, Illinois, Tennessee and Mississippi.  

More severe weather was forecast for Thursday along the Eastern Seaboard, the Storm Prediction Center said. The greatest risk area will be the Northeast. 

On Tuesday, 23 people were injured, including 12 who were hospitalized, after a confirmed tornado struck Salado, Texas, a rural town in Bell County, Bell County Judge David Blackburn said at a news conference

Blackburn said he was thankful no one died.

“There’s not much left,” he said. “Large trees are uprooted and overturned and stripped; buildings really reduced to rubble in many locations. Power lines, power poles are scattered all over the place. It’s pretty devastating.”

In Louisville, Kentucky, a violent storm ripped through the area Wednesday night. More than 19,000 people were without power, according to LG&E. Across the region, about 41,000 LG&E customers were without power.

Texas was still experiencing tens of thousands of power outages Wednesday afternoon, according to poweroutage.us.

Grapefruit-size hail also accompanied the tornado, which was part of a severe storm system stretching from Austin to the Dallas-Fort Worth area, local National Weather Service offices reported. Hail up to 5½ inches in diameter pelted the Salado area, surpassing the weather service’s hail reporting standards that include hail only up to 4½ inches, according to AccuWeather.

The weather service urged residents to seek shelter Tuesday as the tornado barreled toward the town at 30 mph with “very strong rotation.” The weather service called the tornado “a life-threatening situation” and said hail and a “dangerous flash flood” were adding to the threat.

On Wednesday, the weather service said it began surveying damage in Texas’ Williamson and Bell counties.

Several other tornadoes were reported Tuesday night. Damage was reported across several states, including Iowa, where at least two tornadoes were confirmed, according to the Des Moines Register, part of the USA TODAY Network.
