Step 1
Federal radar is already up there
The U.S. radar network sweeps the sky every 2 minutes and estimates where hail fell. It is public data, paid for by taxes — nobody just hands it to you in plain language.

Location reading
No location selected yet.
Estimated intensity
- no signal — Below the event threshold. Radar indicated no relevant hail.
- light — Above the event threshold, in the lowest band of the archive.
- moderate — Mid band of the historical archive.
- severe — High band — most body-damage events land here.
- extreme — Top of the historical archive. Rare.
Ordinal class from measured percentiles. Colors show relative radar signal strength — not hail size.
Technical detail of the 11 bands
MESH quantization bands in inches. This is the internal radar reading, not a hail size measurement (measured correlation r=0.31).
| # | MESH | Class |
|---|---|---|
| 1 | 0.25–0.49 in | no signal |
| 2 | 0.50–0.74 in | light |
| 3 | 0.75–0.99 in | light |
| 4 | 1.00–1.17 in | light |
| 5 | 1.18–1.49 in | moderate |
| 6 | 1.50–1.69 in | moderate |
| 7 | 1.70–1.99 in | severe |
| 8 | 2.00–2.13 in | severe |
| 9 | 2.14–2.99 in | extreme |
| 10 | 3.00–3.99 in | extreme |
| 11 | ≥ 4.00 in | extreme |
light: 0.50–1.17 in · moderate: 1.18–1.69 in · severe: 1.70–2.13 in · extreme: ≥ 2.14 in

How it works, in 3 steps
Step 2
We store it and draw it on a map
Every day we save one slice of that radar and turn it into shading on a map, going back to 2020. The archive grows on its own and lookups stay free.
Step 3
You type a ZIP — or let us tell you
Look it up right now, no sign-up. Want a heads-up next time? Confirm your email. Email only: we never ask for a phone number and we never call.

What this map is not
It is not an expert report, it does not measure hail size, and it does not replace an inspection. It is the best public estimate of where hail passed — with the error stated.
