Midway through April 2026, NOAA's Storm Prediction Center confirms only about 39 US tornadoes, lagging the 1991–2020 monthly average of 182 and far below recent peaks like 2025's 350 preliminary reports, fueling trader uncertainty with tightly clustered market-implied odds around 170–350. A slow early-month pace, despite isolated outbreaks on April 2 and 14–15, reflects suppressed convective available potential energy (CAPE) and weaker vertical wind shear in key Plains setups, differentiating lower bins like 170–199. Higher ranges like 320–350 hinge on late-month escalation from persistent Gulf moisture clashes with jet stream troughs, per SPC outlooks; daily reports through April 30 will clarify escalation risks amid inherent forecast divergence.

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.
