The SPC discussions you provided focus severe potential well outside ID, with the main hail and damaging wind threats centered over the central and southern Plains, the Ozark Plateau, and parts of the Upper Midwest/Great Lakes region, not Idaho.
Statewide maxima from SPC verified reports and NWS warnings, last 12 months. Tornado EF ratings are assigned by NWS survey teams after ground surveys and published in NOAA's final storm records.

How Idaho compares nationally
Ranked by SPC verified storm reports (wind, hail, tornado) across all 50 states over the last 12 months. Severity-weighted index scores each report by hazard (tornado ×20, hail ×4, wind ×1) so a single derecho's flood of wind reports doesn't outweigh tornado outbreaks. Recalculated daily as of Sep 11, 2026.
