May 15th was the arrival day for Tour 4. We did our usual arrival day chase and headed to the panhandle. Moisture wasn’t optimum, but was sufficient for severe storms. Shear was great, and most storms that developed spun quite nicely. We caught one storm near 4 Way and followed it to Stinnett, where we were able to watch it roll across the countryside. This supercell would produce hail baseball size and had nice structure. A great way to start Tour 4!
