Apple-sized hailstones have rained down in Missouri, shattering car windshields amid the deadly storm which impacted millions of Americans this week.  

Dramatic thunderstorms developed quickly Tuesday night, prompting a tornado warning for residents across 10 states in the South and Midwest. 

In Kansas City, local people shared photographs of huge hailstones pounding their lawns, while comparing the natural phenomenon to tennis balls. 

One resident told Fox 4 they found a baseball-sized hole in their car windshield. 

'It was bright and sunny out, and not even a cloud in the sky. While I was sitting in the drive-through, it just kind of rolled in,' resident Christina Peek told the outlet.

'In about five minutes, the wind really picked up,' she added. 

'The hail started while I was in the drive-through, and then it was just a crazy mad dash to get home, and it was hitting my car, golf ball size, and then it just got bigger and bigger to baseball size.'

Peek wasn't the only one dealing with the aftermath. Local resident Mackenzie Vincent also said she found similar damage on her vehicle. 

'I came to look at the car and had the usual dents and stuff,' she told Fox 4. 

'Then I got to the back, and it looked like a couple of baseballs had gone through the back windshield.' 

'It is what it is. Everybody is fine, so we can fix it,' she added.

Around 7pm Tuesday, the National Weather Service warned that a thunderstorm brewing over Missouri could produce a destructive tornado and was moving northeast at 40 mph.

'Tornadoes can develop quickly from severe thunderstorms,' the NWS wrote on its website. 

'If you spot a tornado, go at once into the basement or small central room in a sturdy structure.'

They also urged residents to seek shelter immediately and stay away from windows.

The storm came after meteorologists issued a warning to millions of Americans last week, saying a dangerous weather system was set to sweep across a large swath of the country. 

Parts of Texas, Oklahoma, Kansas, Missouri, Arkansas, Iowa, Illinois and Wisconsin saw hurricane-force wind gusts of up to 80 mph, tornadoes and hail as the powerful system intensified.

The threat followed severe storms that had already unleashed damaging winds, large hail, and tornadoes from Texas to Kansas through Thursday night, according to AccuWeather. 

In northern Oklahoma, a mother and daughter were killed after powerful winds and a dangerous tornado struck the area, authorities said. 

Meteorologist Matthew Cappucci with MyRadar warned the worst conditions could still be ahead.

'The main hazards are large hail up to hen egg size and damaging winds, but there's a decent chance of some tornadoes too,' he shared on Facebook.
