Evidence / storm surfaces
How Truckee 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.
Radar signature field The point detections NEXRAD recorded overhead. Each signature marks where the radar saw hail aloft — it is a detection, not a stone measured on the ground.
Only the NEXRAD radar-signature surface resolved for May 3, 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 May 3, 2026 sits in Truckee's hail record.
This was Truckee's 2nd recorded hail day, arriving 1 day after the May 2, 2026 storm. By severity it ranks 1st of the 2 storms we have logged here. Radar put the day's largest stone over Truckee at 0.5" — the largest NEXRAD radar signature.
The May 3, 2026 convective day was bigger than Truckee: the same system put hail over 115 other tracked cities, 4 of them in California. Nearest: Downieville (30 miles northwest, up to 1.25"); Coleville (76 miles southeast, up to 0.5"); Shingletown (106 miles northwest, up to 0").
These maps are stills. In the app this date is one of 2 Truckee 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.
Nobody on the ground filed a report over Truckee for this date, which says more about who was watching than about the storm: spotter reports only exist where there is an observer. The radar surfaces above carry the evidence for this one.
Below the severe threshold
What 0.5" hail means for Truckee 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
$18M
Potential roof exposure — 1,481 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 7 jobs
- Illustrative work
- ~$105K
Close just 0.5% of the 1,481 homes in this footprint at the average $15,000 roof job. Illustrative math, not a projection — your results depend on your outreach and how the market responds.
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 $311 on top of the $150 plan.
