⚡ Haily's Briefing

Illinois has no active hail or wind alerts right now, but SPC’s mesoscale discussions point to a broader severe setup nearby that could matter later today and tonight. The main threat corridor is focused farther north across parts of the Upper Midwest, where SPC notes scattered severe storms capable of large hail up to 2+ inches, damaging winds, and a couple of tornadoes; they also mention a separate risk for locally damaging wind gusts in the 55–70 mph range and hail up to 1.25 inches in nearby convection.

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.

Proudly AI-powered. Honestly sourced. IDOLCheck is built by HailyAI. Every storm event, magnitude, radar snapshot, and date on this page is deterministic — retrieved directly from official NOAA, National Weather Service (NWS), and Storm Prediction Center (SPC) storm records through our HailyDB engine and displayed exactly as reported. Quoted warning and report text is always attributed to its official source. Where the surrounding copy is not a direct quote, it was generated with AI assistance from that same verified storm data and reviewed and approved by humans before publication. AI organizes and presents the record — it never invents storm data.
