How Los Alamos saw the hail — from two instruments
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.
Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.
Only the radar-estimated size surface resolved for Jul 27, 2026 — this storm produced no NEXRAD point detections over Los Alamos, so there is one map to show, not two.
Where Jul 27, 2026 sits in Los Alamos's hail record
This was Los Alamos's 5th recorded hail day, arriving 3 days after the Jul 24, 2026 storm. By severity it ranks 2nd of the 7 storms we have logged here. Radar put the day's largest stone over Los Alamos at 0.75" — radar-estimated size aloft.
The Jul 27, 2026 convective day was bigger than Los Alamos: the same system put hail over 803 other tracked cities, 17 of them in New Mexico. Nearest: Pena Blanca (21 miles south, up to 0.5"); Jemez Springs (22 miles west, up to 0.5"); Rociada (45 miles east, up to 0.5").
These maps are stills from Los Alamos's Jul 27, 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.
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.
No ground reports were filed with the National Weather Service for this storm over Los Alamos. That is common: a report depends on someone being there to see it and take the time to call it in. The radar surfaces above are the record here — the storm was detected from above even though no one on the ground logged it.
What 0.75" hail means for Los Alamos roofs
Hail this size sits right at the edge of the National Weather Service severe threshold. Newer roofs usually shrug it off, but aging or already-worn shingles can bruise, and soft metals — vents, flashing, gutters — often show the first dents.
