Event & radar context
The later NWS tornado table gives 17:26–18:48 CST (18:26–19:48 CDT); an older narrative starts three minutes earlier. Surrounding scans cover both accounts. This event used the original Fujita scale. RhoHV did not exist in this radar archive.
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.
