Traders heavily favor 170–199 US tornadoes in April (51.5% implied odds) as aligning closest to NOAA's historical median of 177, amid confirmation delays for preliminary reports surpassing 300 from explosive mid-month outbreaks. Persistent atmospheric drivers—warm Gulf moisture clashing with potent mid-level jets and extreme CAPE values over the Plains—propelled this into one of April's most active periods on record, elevating 320–350 odds to 41%. Recent Storm Prediction Center updates verifying high EF0+ counts reinforce these leaders, while climatological norms and ongoing damage surveys temper extremes, with final tallies expected soon.
