The National Weather Service Storm Prediction Center's latest Day 1 convective outlook for September 25, 2026, indicates no organized severe thunderstorm areas are forecast nationwide, reflecting limited buoyancy, modest mid-level lapse rates, and weak deep-layer shear that suppress supercell or tornado potential. Scattered thunderstorms are possible over parts of the Southwest and southern Rockies, with low-confidence isolated stronger cells late in the day over western Oklahoma or eastern New Mexico that could briefly produce gusts or small hail but lack parameters for organized severe weather. Official monitoring shows no active tornado watches or warnings as of midday, consistent with climatological expectations for late-September patterns featuring an upper ridge over the Plains. Traders should monitor the next SPC update and any mesoscale discussions for rapid changes in instability or shear that could introduce localized risk.
