March 10 appeared to be a marginal day for severe weather across the Texas panhandle. With nothing else to do, I decided to head south from Denver to see what would form. Limited moisture was the main problem, but very cold air aloft and decent wind shear would help to produce several high based supercells this day. Many of them produced hail quarter size, with up to ping pong ball sized reported with the storm featured here. Near dark as the cells merged into a southeast moving MCS, the anvil crawler show began.
