Evidence / storm surfaces
How Rio Rico 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.
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.
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 Aug 29, 2026 sits in Rio Rico's hail record.
This was Rio Rico's 8th recorded hail day, arriving 6 days after the Aug 23, 2026 storm. By severity it ranks 9th of the 9 storms we have logged here. Radar put the day's largest stone over Rio Rico at 0.5" — radar-estimated size aloft.
The Aug 29, 2026 convective day was bigger than Rio Rico: the same system put hail over 113 other tracked cities, 15 of them in Arizona. Nearest: Sonoita (20 miles northeast, up to 0.5"); Sells (50 miles northwest, up to 0.75"); Globe (121 miles north, up to 0.5").
These maps are stills. In the app this date is one of 9 Rio Rico 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.
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.
For this storm over Rio Rico, the NWS report log is empty — a common outcome, since ground reports only happen when someone witnesses the hail and takes the time to call it in. The detection record for the date lives in the radar maps above.
Below the severe threshold
What 0.5" hail means for Rio Rico roofs.
Radar signals under three-quarters of an inch stay below the National Weather Service severe threshold and generally indicate lower roof risk. Older or already-worn materials can still show effects, but radar alone cannot determine whether a specific roof was damaged.
