We headed to northern Oklahoma this day for what appeared to be a high risk/high reward setup. By late afternoon a few supercells developed on the dryline and intensified as the evening progressed. The low level jet strengthened as stronger mid and upper level flow overspread the region, creating a nicely sheared environment. One supercell spun like crazy as a wall cloud formed directly overhead, while another became a classic monster after dark.
