With roughly 63 tornadoes confirmed through April 16 per preliminary National Weather Service surveys—below the 1991–2020 monthly average of 182—trader consensus clusters around 170–199 (30%) and 200–229 (23%), reflecting projections for typical late-April escalation in supercell activity across the Plains and Midwest. Recent outbreaks on April 13–17, fueled by strong wind shear, high CAPE values exceeding 2,000 J/kg, and dynamic cold fronts, added over 20 tornadoes including EF2–EF3 events in Kansas, Wisconsin, and Iowa, lifting the count and narrowing lower bins like <140 (8.5%). Differentiation hinges on Storm Prediction Center outlooks for Days 4–8: sustained moisture and jet streak support for 100+ more could push toward 230+, while high-pressure ridging might cap at 170–199; final NCEI tally releases May 8.

Only tornadoes appearing in the final NCEI dataset for that month will count.
As of market creation, the relevant report is scheduled to be released on May 8, 2026, at 5:00 PM GMT+1 or 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 ET, 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.
