Storms developed southwest to northeast aiming right for Norman. We targeted the northeasternmost cell that crossed an outflow boundary near the town of Dibble. It sported marginal supercell characteristics and even had calved off a small mesocyclone. Then we watched in horror as a bow echo swallowed this small mesocyclone and then continued after us. We were also swallowed up east of Lexington, OK. What a beautiful green core it had though.
