Event & radar context
Timing and dimensions follow the later NWS 2024 annual tornado table. That table uses Central Standard Time year-round; times here are converted to daylight time. Earlier event summaries give different preliminary dimensions and an earlier end time.
Interpreting the rating
F, EF and IF are different damage-rating scales. Original source labels are preserved. Badge colours group the numerical categories for browsing; they do not imply identical wind thresholds. Radar products do not directly establish the damage rating.
