Trader consensus favors 170–199 US tornadoes in April at 49.5% implied probability, driven by the Storm Prediction Center's preliminary count of around 140 confirmed events midway through the month, on pace with the long-term NOAA average of 177. Favorable spring patterns—clashing Gulf moisture, strong low-level shear, and jet stream dynamics—support elevated activity in the Plains and Southeast, mirroring 2023's 162 tally. Recent outbreaks, including over 30 tornadoes from April 25–28 storms, have boosted higher-range odds like 230–259 (39%), while cooler La Niña transition tempers extremes beyond 350. Upcoming model guidance from NOAA's Storm Prediction Center will refine trajectories amid inherent forecast uncertainty.

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.
