Evidence / storm surfaces

How Tucson saw the hail — from two instruments

Jul 8, 2026 · Tucson, AZ

We map this storm two ways: the NEXRAD radar signatures the storm produced overhead, and the radar-estimated size of the hail in the air. The two surfaces don’t have to match — where they diverge is where estimated size aloft ran ahead of, or behind, what the signatures caught.

NEXRAD radar signatures — the point detections the storm produced overhead. A signature is where the radar saw hail, not a confirmed stone on the ground.

The storm in context

Where Jul 8, 2026 sits in Tucson's hail record.

This was Tucson's 3rd recorded hail day, arriving 13 days after the Jun 25, 2026 storm. By severity it ranks 8th of the 18 storms we have logged here. Radar put the day's largest stone over Tucson at 1.75" — the largest NEXRAD radar signature.

The Jul 8, 2026 convective day was bigger than Tucson: the same system put hail over 908 other tracked cities, 6 of them in Arizona. Nearest: Benson (25 miles southeast, up to 1.25"); Sells (29 miles west, up to 1"); Bylas (62 miles northeast, up to 1").

These maps are stills. In the app this date is one of 18 Tucson storm dates on a live map — both surfaces, the reports, and a replay — and the same map is where you draw the swath. This page rebuilds nightly.

Timing and place names from NOAA ground reports

Reports came from Sells — beyond Tucson itself.

High damage potential

What 1.75" hail means for Tucson roofs.

Hail around an inch and a half is capable of cracking shingles, stripping granules, and denting gutters, vents, and siding. Risk is usually greatest near the strongest radar signal, but property-level damage still requires an on-site inspection.

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 tells you where to look. Only an inspection confirms damage at an address. Last updated Sep 15, 2026.
