Two ways to read the storm

How Supai saw the hail — from two instruments

Two instruments, one storm: NEXRAD logs the point signatures it detected overhead, while the estimated-size surface models how large the hail aloft could have grown. Agreement between them is not guaranteed — the gaps are where the model ran ahead of, or behind, the detections.

Radar-estimated maximum hail size across the swath, modeled from radar aloft. It reflects the biggest stone the storm could support, which may differ from what actually fell.

The storm in context

Where Jul 29, 2026 sits in Supai's hail record

This was Supai's 2nd recorded hail day, arriving 11 days after the Jul 18, 2026 storm. By severity it ranks 1st of the 2 storms we have logged here. Radar put the day's largest stone over Supai at 1.5" — the largest NEXRAD radar signature.

The Jul 29, 2026 convective day was bigger than Supai: the same system put hail over 359 other tracked cities, 19 of them in Arizona. Nearest: Peach Springs (56 miles south, up to 1"); Littlefield (56 miles northwest, up to 0.5"); Saint George (56 miles northwest, up to 0.5").

These maps are stills from Supai's Jul 29, 2026 storm. In the Overview app the same surfaces are live — radar updating in real time, radar-estimated hail size as it forms, and NWS spotter reports pinned where they're filed — with a radar replay you can scrub back over any past day.

Ground reports

What people on the ground reported

These are storm reports filed with the National Weather Service and released through the NOAA Storm Prediction Center — public-domain observations from spotters, the public, and NWS surveys. We quote each one exactly as filed.

No ground reports were filed with the National Weather Service for this storm over Supai. That is common: a report depends on someone being there to see it and take the time to call it in. The radar surfaces above are the record here — the storm was detected from above even though no one on the ground logged it.

Widespread claimable damage

What 1.5" hail means for Supai roofs

At an inch and a half, hail cracks shingles, strips granules down to the mat, and dents gutters, vents, and siding. A footprint like this typically produces a wave of insurance claims — and the contractor who reaches the homeowner first usually gets the inspection.

What this storm is worth to a roofer

$144K

Potential roof exposure — 12 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Claims from this storm can typically be filed until around July 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.

Other storms in Supai

A storm day here is a convective day — it runs from noon to noon UTC, so late-night hail is grouped with the afternoon storm that spawned it rather than split across two calendar dates. Ground reports are public-domain observations from the NOAA Storm Prediction Center. Radar surfaces are detections and estimates, not confirmed damage. Last updated Aug 1, 2026.
