Evidence / storm surfaces
How Livermore 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.
Only the NEXRAD radar-signature surface resolved for Jul 22, 2026 — the estimated-size swath had no hail signal to model for this storm, so there is one map to show, not two.
The storm in context
Where Jul 22, 2026 sits in Livermore's hail record.
This was Livermore's 6th recorded hail day, arriving 1 day after the Jul 21, 2026 storm. By severity it ranks 3rd of the 7 storms we have logged here. Radar put the day's largest stone over Livermore at 0.75" — the largest NEXRAD radar signature.
The Jul 22, 2026 convective day was bigger than Livermore: the same system put hail over 158 other tracked cities, 28 of them in Colorado. Nearest: Winter Park (74 miles south, up to 0.75"); Strasburg (88 miles southeast, up to 1"); Merino (96 miles east, up to 1.75").

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.
The National Weather Service logged no spotter reports for this storm over Livermore. 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.
Near the severe threshold
What 0.75" hail means for Livermore roofs.
A signal this size sits near the National Weather Service severe threshold. Aging shingles and soft metals such as vents, flashing, and gutters may be more vulnerable; roof age, wind, and material condition all matter, and only an inspection can confirm damage.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$12K
Potential roof exposure — 1 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Claim window
July 2028
Claims from this storm can typically be filed until around July 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.
Names and phones for every home in the footprint: at most $0 on top of the $150 plan.
