Stone. Louis - At least seven people were killed and authorities searched from buildings to buildings, people trapped or injured in severe storms, including at least one possible tornado that swept Missouri.

The storms are part of Friday’s bad weather system that wreak havoc in Missouri, where the Wisconsin tornado left hundreds of thousands without electricity in the Great Lakes area and brought a punishment heat wave to Texas.

Friday afternoon storm ripped off the roof of the building, blew up windows, ripped bricks from the siding, and pulled up trees and wires. St. Louis Mayor Cara Spencer confirmed five deaths in her city and said more than 5,000 homes were affected, and about 100,000 customers were out of power on Friday night.

"It's really devastating," Spencer said, adding that the city is declaring an emergency and the biggest loss occurred nearby on Friday.

The number of injured people is not immediately known. Barnes-Jewish Hospital received 20 to 30 patients from the storm, some of which were severe and most expected to be discharged Friday night, according to hospital spokesman Laura High.

She said St. Louis Children's Hospital has received 15 patients, two of whom are expected to stay in the hospital until the weekend.

The National Weather Service said the tornado landed in Clayton, the St. Louis area, Missouri, between 2:30 and 2:50 pm. The obvious tornado was in the Forest Park area, the location of the St. Louis Zoo and the location of the 1904 World Expo and the Olympic Games of the same year.

At the Centennial Christian Church, William Pollihan, chief chief chief of the St. Louis Fire Department, told the Associated Press that three people must be rescued after part of the church collapses. One of them died.

Stacy Clark said his mother-in-law, Patricia Penelton, died in the church. He describes her as a very active church volunteer who plays many roles, including being part of the choir.

Jeffrey Simmons Sr., who lives across from the church, heard an alarm on his phone and the light went out.

"Next, you know, a lot of noise, a lot of wind," he said, and he and his brother walked into the basement. Later, he realized it was worse than he thought. “Everything was torn.”

Falling trees and parking lights also caused traffic stalemate during a Friday afternoon commute, and officials urged people to stay home.

When the storm hit, the upper story of the brick building in Harlem Hill Room was demolished, leaving a pile of bricks outside. According to the St. Louis Post, about 20 people were inside, but they were crowded behind the building and no one was injured.

John Randle, 19-year-old University of Missouri. Louis's students said he and his girlfriend were at the St. Louis Museum of Art during the storm and were busy with the basement with about 150 other people.

He said they could hear the sound of branches, hail hit the building's window, and Randall climbed the stairs and flew to the main entrance for about 10 seconds.

"You can see the doors open, the branches fly, people run," he said. "A lot of people are driven outside."

St. Louis Zoo spokesman Christy Childs said in the text that the zoo will be closed on Saturday due to trees and other damages. Childes said all animals were safe and there were no reports of injuries to staff, guests or animals.

"We can't say clearly whether this is a tornado - it could be," said Marshall Pfahler, a meteorologist at the National Meteorological Service.

Sheriff Derick Wheetley wrote on social media that the tornado attacked Scott County about 130 miles (209 kilometers) south of St. Louis, killing two people, injuring several others and destroying multiple homes.

"Even if the tornado is still active, our first responders act quickly, which hurts themselves and provides immediate assistance and care for the injured," he said.

Appalachia and the Midwest face danger

Weather forecasters warn that there could be storms of tornadoes, hail and even hurricanes on Friday, and could even bypass parts of Appalachia and the Midwest on Friday.

On Friday night, the Weather Service warned of a rare tornado emergency around Marion, Illinois, saying the tornado has been confirmed and life-threatening. Reports of damage and injury are not immediately available.

A dust warning was issued Friday night around the Chicago area. The 100-mile (161 km) line from southwest Chicago to northern Indiana runs along a dust wall, which severely reduces visibility, the Weather Service said.

Residents in Kentucky, southern Indiana, southern Illinois, Tennessee, Missouri, Arkansas and Ohio should be prepared for a massive storm that could include baseball-sized hail, the National Weather Service said.

The Bureau's Storm Prediction Center said it could be expected that "strong, possibly long-distance tornadoes and very large hail". As the storm grows into larger clusters, the threat to damage winds over 75 mph (120 kph) will increase to Friday night.

The Appalachian power, which serves 1 million customers in West Virginia, Virginia and Tennessee, said it requested 1,700 workers from neighboring utilities while dispatching crew members from unaffected areas to assist with the service’s restoration.

Faith Borden, a meteorologist at the National Weather Service’s Nashville office, said Friday that central Tennessee can expect “harsh weather of all types. Top speeds up to 70 mph. What we are seriously talking about is large hail as high as 3 inches, which is large hail for us.”

Texas is hit by heat waves

Texas faces scorching heat. Heat consultation was sent for San Antonio and Austin at a temperature of 95 F (35 C) to 105 (40.5 C). From Virginia to part of the southern coast of Florida, fighting heat in the 90s (32-37 c).

The National Weather Services Office in Austin/San Antonio said Friday that humidity will cause higher temperatures over the weekend.

“People are concerned that people who have not taken appropriate precautions should take appropriate precautions when they are outdoors,” said Jason Runyen, a meteorologist.

Over the night Thursday, the storm was accompanied by thunder, lightning displays and powerful winds swept through parts of Wisconsin, Illinois, northern Indiana and Michigan, leaving dozens of trees and thousands of homes without power.

Several tornadoes landed in central Wisconsin on Thursday. There was no distorted viewership on Thursday, said Timm Uhlmann, a meteorologist at Green Bay National Weather Service.

"We are still collecting reports," Ulman said. "We are evaluating some of the losses and still receiving videos and pictures. The damage we suffer is quite common. There is a lot of hail.

No immediate report of injury.

Steven Freitag, a meteorologist with the National Weather Service in White Lake town in northwestern Detroit, said damage was also under investigation in Michigan on Friday to determine if any tornadoes landed.

Fretag said that during the low temperatures in the 1980s (26-29 c), temperatures extending from Illinois to Michigan fueled the storm.

By Friday night, customers in Michigan saw the power return, but nearly 190,000 people still had no electricity. The power outage was also recorded Friday night in six other states, including Missouri and Indiana.

The threat of bad weather in Chicago delayed Beyoncé's concert about two hours Thursday at Soldier Field.
