Chased the north-central Oklahoma supercell with Scott Blair, Katie Burtis, Amos Magliocco, and Scott Eubanks observing 6 tornadoes. We departed Salina, KS by late morning with a target near the intersection of the dryline and outflow boundary. We obtained our first visual of the storm near Bison, OK with a well defined wall cloud quickly developing. An elephant trunk tornado soon evolved, persisting for approximately 5 minutes 6 miles WSW of Douglas. The storm slowly moved east from Douglas to south of Covington, producing several more tornadoes including a large cone. Another photogenic tornado developed about 9 miles SW of Perry and persisted for approximately 10 minutes. Ended the day in Morrison with a fantastic chicken fried steak dinner.
