**Trader sentiment reflects high uncertainty in September tornado totals amid the transitional fall pattern, where reduced wind shear and instability typically limit activity to a 1991–2020 average of roughly 66 tornadoes.** With about 20 days remaining, current SPC outlooks indicate only marginal severe risk focused on damaging winds rather than tornadoes across the Ohio Valley and Plains, consistent with climatology showing fewer supercell-favorable environments as the jet stream shifts. Differentiating the closely matched bins hinges on whether late-month setups produce typical scattered events or an outlier driven by Gulf moisture surges, tropical cyclone remnants (which historically spawn dozens in concentrated outbreaks), or an unusually strong low-level jet enhancing shear and CAPE. Historical extremes—from single-digit months to 295 in 2004—underscore the role of these episodic catalysts versus baseline conditions in tipping counts across the 25–124 range or beyond.
