Storm trackers in the Texas Panhandle recovered a massive hail stone that researchers say is likely to be a new state record.

Val and Amy Castor, veteran storm chasers with Oklahoma City television station KWTV, discovered a piece of hail more than 7 inches (17.78 centimeters) long Sunday along the side of the road near Vigo Park while they were chasing a major thunderstorm system.

Val Castor said the stone was about the size of a pineapple.
