Evidence / storm surfaces
How Santa Rosa saw the hail — from two instruments
Each storm gets two readings: the radar signatures NEXRAD recorded as the cells passed overhead, and a modeled estimate of hail size in the air. They are independent surfaces, so a mismatch between them is expected — and worth reading.
Estimated size field Radar-estimated hail size over the swath. The model reports the biggest stone the storm could sustain in the air; what actually fell may have been smaller.
Only the radar-estimated size surface resolved for May 23, 2026 — this storm produced no NEXRAD point detections over Santa Rosa, so there is one map to show, not two.
The storm in context
Where May 23, 2026 sits in Santa Rosa's hail record.
This was Santa Rosa's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 8th of the 9 storms we have logged here. Radar put the day's largest stone over Santa Rosa at 0.5" — radar-estimated size aloft.
The May 23, 2026 convective day was bigger than Santa Rosa: the same system put hail over 222 other tracked cities, 2 of them in New Mexico. Nearest: Las Vegas (49 miles northwest, up to 0.75"); Friona (111 miles east, up to 1.25"); Muleshoe (116 miles southeast, up to 0.75").

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 Santa Rosa. 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.
Below the severe threshold
What 0.5" hail means for Santa Rosa 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.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$372K
Potential roof exposure — 31 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Claim window
May 2028
Claims from this storm can typically be filed until around May 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 $7 on top of the $150 plan.
