National Weather Service Storm Prediction Center outlooks for September 25, 2026, showed no severe thunderstorm areas across the contiguous U.S., with only marginal or zero tornado probabilities in Day 1 and Day 2 products. Limited surface heating, weak shear, and modest instability confined any convection to isolated, non-organized cells, primarily over the southern Plains and Rockies. A single landspout was reported in Comanche County, Kansas, consistent with the low-end environment. Authoritative SPC and local NWS data, rather than model runs, determine resolution criteria such as official tornado warnings or verified reports. With the period now complete, traders assess final confirmation from preliminary storm reports and any subsequent surveys.
