June 21st, 2007 South Dakota and Nebraska Supercells

It is a rare occasion that you get woken up at 6 AM with a TORNADO WARNED supercell out your window! June 21st was one of those days! A cluster of supercells developed overnight and moved southeast across south central South Dakota. We intercepted one near Kimball, SD that produced 4.25 diameter hail! Later that day, an old boundary would provide the lift and convergence to develop the best storm of the day, that also produced hail to 3.5″ in diameter!
