Lightning flashed as hail pelted Willmar, Minnesota, on the morning of Monday, May 9. The National Weather Service issued a extreme thunderstorm warning for elements of the state, predicting hail as massive as tennis balls, lightning, and winds of as much as 70 mph. This video exhibiting the early morning scene was recorded by Simon Glinsek, who stated a few of the hailstones had been “close to ping-pong” balls in measurement.
