How California 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.
NEXRAD radar signatures — the point detections the storm produced overhead. A signature is where the radar saw hail, not a confirmed stone on the ground.
Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.
Where Jul 9, 2026 sits in California's hail record
This was California's 8th recorded hail day, arriving 4 days after the Jul 5, 2026 storm. By severity it ranks 2nd of the 9 storms we have logged here. Radar put the day's largest stone over California at 1.75" — the largest NEXRAD radar signature.
The Jul 9, 2026 convective day was bigger than California: the same system put hail over 944 other tracked cities, 140 of them in Missouri. Nearest: Clarksburg (5 miles west, up to 0.5"); Centertown (11 miles east, up to 1.75"); Russellville (13 miles southeast, up to 1").
These maps are stills from California's Jul 9, 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.
The National Weather Service logged no spotter reports for this storm over California. That absence is ordinary — filing a report takes a person on the spot who saw the hail and phoned it in. What stands as the record for this date is the radar above, which caught the storm regardless.
What 1.75" hail means for California roofs
At an inch and a half, hail cracks shingles, strips granules down to the mat, and dents gutters, vents, and siding. A footprint like this typically produces a wave of insurance claims — and the contractor who reaches the homeowner first usually gets the inspection.
