End of March CA chase day

On Sunday, March 31, 2013, I got a chance to do a little storm chasing in California. While the convection coming off the Diablo range near Tracy, CA never really got organized while I was out there, I did manage to observe rain rates in excess of 1" per hour along with a few dime-sized hail stones as well as some accumulation of pea-sized hail on the road.
