Early September 2026 severe weather outlooks from the Storm Prediction Center indicate only marginal to slight risks, primarily for damaging winds across the Southeast and isolated hail or wind in the Plains, with minimal tornado probabilities amid a persistent mid-level ridge and limited low-level moisture or shear. Quiet Atlantic tropics reduce potential for landfalling systems or remnants that often boost fall tornado counts. These conditions align with historical September averages near 66 reports but favor the lower end absent stronger synoptic forcing or tropical influences. Trader consensus between the 25-49 and 50-74 bins reflects uncertainty in how quickly mid-latitude patterns may evolve versus climatological suppression during early fall.

This market will resolve according to the number of tornadoes recorded in the United States during the specified month, based on the monthly count published on the National Centers for Environmental Information U.S. Tornadoes Time Series page (see: https://www.ncei.noaa.gov/access/monitoring/tornadoes/time-series).
Only tornadoes appearing in the final NCEI dataset for that month will count.
The brackets are mutually exclusive and collectively exhaustive: each range is inclusive of both of its stated endpoints, and the monthly tornado count falls within exactly one bracket.
As of market creation, the relevant report is scheduled to be released on October 14, 2026 at 11:00 AM ET (Release schedule: https://www.ncei.noaa.gov/access/monitoring/dyk/monthly-releases). The market will resolve based on the first relevant tornado count published on the NCEI tornado time-series page after this scheduled release time.
If the value published after this scheduled release time is labeled preliminary, it will still determine resolution, and the market will resolve independently of any subsequent revisions, corrections, or retroactive adjustments.
The market will not resolve based on any preliminary values published before the scheduled release time.
If no data is published by the scheduled release time, or if the NCEI website is temporarily unavailable, this market will remain open until that data is made available. If the relevant data is not made available by the date of the next scheduled publication, this market will resolve based on available data for the most recent prior month. If the NCEI website becomes permanently unavailable, this market will resolve using another credible source.Early September 2026 severe weather outlooks from the Storm Prediction Center indicate only marginal to slight risks, primarily for damaging winds across the Southeast and isolated hail or wind in the Plains, with minimal tornado probabilities amid a persistent mid-level ridge and limited low-level moisture or shear.
