Evidence / storm surfaces
How Tucson saw the hail — from two instruments
Aug 5, 2026 · Tucson, AZ
Each storm gets two readings: the radar signatures NEXRAD recorded as the cells passed overhead, and a modeled estimate of hail size in the air. They are independent surfaces, so a mismatch between them is expected — and worth reading.
NEXRAD radar signatures Surface resolved
Radar signature field The point detections NEXRAD recorded overhead. Each signature marks where the radar saw hail aloft — it is a detection, not a stone measured on the ground.

Radar-estimated hail size Surface resolved
Estimated size field Radar-estimated hail size over the swath. The model reports the biggest stone the storm could sustain in the air; what actually fell may have been smaller.

The storm in context
Where Aug 5, 2026 sits in Tucson's hail record.
This was Tucson's 9th recorded hail day, arriving 9 days after the Jul 27, 2026 storm. By severity it ranks 2nd of the 16 storms we have logged here. Radar put the day's largest stone over Tucson at 1.75" — radar-estimated size aloft.
The Aug 5, 2026 convective day was bigger than Tucson: the same system put hail over 243 other tracked cities, 29 of them in Arizona. Nearest: Vail (27 miles southeast, up to 1.25"); Sahuarita (28 miles south, up to 1.25"); Benson (41 miles southeast, up to 0.5").
These maps are stills. In the app this date is one of 16 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.

Storm forensics
How the storm moved
Timing and place names from NOAA ground reports
Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.
The storm tracked north at roughly 25 mph, based on the timing of ground reports.
Hail was reported over 60 minutes, from to .
Reports came from Three Points and Green Valley — 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 Aug 28, 2026.
