Evidence / storm surfaces
How Tucson saw the hail — from two instruments
Jul 11, 2026 · Tucson, AZ
The maps here read the same storm from two angles — point detections from NEXRAD, and modeled hail size aloft. Where the two disagree is informative: it marks where estimated size outran the signatures, or trailed them.
NEXRAD radar signatures Surface resolved
Radar signature field Where NEXRAD flagged hail as the storm passed — point signatures from the radar, which indicate hail overhead rather than confirm what landed.

Radar-estimated hail size Surface resolved
Estimated size field The modeled maximum hail size across the swath, derived from radar aloft — the largest stone the storm could have supported, which is not necessarily what reached the ground.

The storm in context
Where Jul 11, 2026 sits in Tucson's hail record.
This was Tucson's 4th recorded hail day, arriving 3 days after the Jul 8, 2026 storm. By severity it ranks 4th of the 18 storms we have logged here. Radar put the day's largest stone over Tucson at 1" — the largest NEXRAD radar signature.
The Jul 11, 2026 convective day was bigger than Tucson: the same system put hail over 483 other tracked cities, 24 of them in Arizona. Nearest: Mount Lemmon (12 miles northwest, up to 2.5"); Vail (16 miles southeast, up to 1.5"); Oracle (25 miles north, up to 1.75").
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.

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 south at roughly 10 mph, based on the timing of ground reports.
Hail was reported over 34 minutes, from to .
Damage-capable hail signal
What 1" hail means for Tucson roofs.
Quarter-size and larger hail can bruise asphalt mats, remove granules, and dent exposed soft metal. The mapped footprint identifies an inspection priority area — it does not identify which individual roofs, if any, sustained damage.

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.
