Check a specific address for this date →These dates are GMT, not local. GMT runs 5–8 hours ahead of the US, so a storm that hit at 8:30 PM local on one evening is recorded here under the following date. Evening storms are the norm across the Plains and the Southeast. If you are writing a date of loss on a claim form, check the local time — being one day off is a real reason a carrier can push back.

These are city-centre tiles. To see whether radar registered hail over your street on May 1, 2007 — and every other date going back to 1992 — run the free address lookup. No signup, no account, and you can download the result as a CSV.
Look up your address →What a detection means. Counts describe a 0.1° grid tile — roughly 7 miles north to south — containing the city, not a specific address. A detection inside the tile does not prove hail fell on any particular roof, and no detection does not prove none fell. This is a screening tool, not an insurance claim, a loss report, or an engineering inspection.
