How Tucson saw the hail — from two instruments
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
Where NEXRAD flagged hail as the storm passed — point signatures from the radar, which indicate hail overhead rather than confirm what landed.

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 2nd of the 8 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: Rio Rico (37 miles southeast, up to 2.75"); Vail (39 miles east, up to 1.5"); Patagonia (45 miles southeast, up to 2.75").
These maps are stills from Tucson's Jul 11, 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.

How the storm moved
The storm tracked south at roughly 10 mph, based on the timing of ground reports.
Hail was reported over 34 minutes, from to .
What 1" hail means for Tucson roofs
Quarter-size and larger hail is where asphalt shingle damage starts in earnest: bruised mats and granule loss that homeowners can't see from the ground. Most people inside the footprint won't know their roof was hit until someone inspects it.

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 3, 2026.
