June 15th featured very high dewpoints and instability, as well as good shear and several boundaries for storms to form on. A cluster of storms formed in southwest Oklahoma later in the afternoon and became severe. We followed them towards Lawton as another storm developed on it eastern flank. As we approached Commanche it became tornado warned. Just north of town, it developed a rather large wedge tornado that persisted for over a half hour although it became rain wrapped. If was briefly visible near Loco, OK and caused EF2 damage along the way. After the storm weakened we dropped south on a tail end supercell that was just gorgeous and also tornado warned. Our thoughts and prayers for the town of Perryton, TX that was also hit by an EF3 tornado that day causing much damage and a few fatalities. The down side of storm chasing.
