⚡ Haily's Briefing

Severe storms are still a concern across South Dakota this evening, especially in the northeast where SPC says inhibition is eroding ahead of a cold front and storms could organize along the corridor into west-central Minnesota and northeast SD. SPC’s guidance points to large hail around 1.5 to 2.5 inches, wind gusts near 55 to 70 mph, and even a tornado risk in the stronger cells, with a broader Upper Midwest threat for some 2+ inch hail, damaging winds, and a couple of tornadoes late today and tonight.

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.
