**SPC Day 1 convective outlooks for October 1, 2026, placed a marginal (level 1) severe risk across southern Kansas into northwest Oklahoma, citing modest instability, a progressive cold front, and ambient low-level vorticity that could support brief non-supercell tornadoes alongside gusty winds.** Official probabilistic graphics showed tornado probabilities peaking near 2% in that corridor, with no higher-risk areas delineated for major population centers. Earlier 0100 UTC guidance had referenced slight-risk wording for portions of Texas and north-central Kansas before trimming as conditions evolved overnight. Model guidance and surface observations indicated limited deep-layer shear and marginal lapse rates, keeping overall severe potential low through the afternoon and evening. Traders monitoring real-time SPC updates and short-term mesoscale discussions would have focused on any last-hour adjustments to the risk area or confirmed tornado reports before market resolution.
