IDOLCheck does not verify storm evidence at a property. We combine official reports and warning records to show the relevant storm activity associated with a specific address or location, including the most recent 30 days.

SPC ground truth. Ranked by the largest measured hailstone in that county in the window. NWS radar-classified hail is left off — in our cache it never reaches 1.00″, even when the warning text cites quarter or golf-ball hail. Stones above 8" are dropped as bad fields.
30-day gate. Events from the last 30 days show month-only dates and no official quote. Full report text unlocks after that, or immediately in the app.
Week and month cuts use midnight America/Chicago (SPC convention). This week runs Sunday through today.
