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 HailyAPI 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.
