Severe storms raked the upper Midwest and High Plains last Friday. The Storm Prediction Center says that one of the hail stones may have set a world record for size and weight. 

The current record-holding hailstone fell from a severe thunderstorm in southeastern Nebraska on June 22, 2003. That stone measured 7 inches in diameter with a circumference of 18.75 inches.

The chunk of ice that was found by a ranch hand near the town of Vivian on Friday night, unofficially measured 8 inches in diameter with an 18.5-inch circumference.
