Evidence / storm surfaces
How San Jon 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.
Estimated size field 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 Aug 16, 2026 — this storm produced no NEXRAD point detections over San Jon, so there is one map to show, not two.
The storm in context
Where Aug 16, 2026 sits in San Jon's hail record.
This was San Jon's 4th recorded hail day, arriving 15 days after the Aug 1, 2026 storm. By severity it ranks 3rd of the 4 storms we have logged here. Radar put the day's largest stone over San Jon at 1" — radar-estimated size aloft.
The Aug 16, 2026 convective day was bigger than San Jon: the same system put hail over 264 other tracked cities, 7 of them in New Mexico. Nearest: Tucumcari (18 miles southwest, up to 1"); Vega (54 miles east, up to 0.5"); Dalhart (61 miles northeast, 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.
For this storm over San Jon, the NWS report log is empty — a common outcome, since ground reports only happen when someone witnesses the hail and takes the time to call it in. The detection record for the date lives in the radar maps above.
Damage-capable hail signal
What 1" hail means for San Jon roofs.
Quarter-size and larger hail can bruise asphalt mats, remove granules, and dent exposed soft metal. The mapped footprint identifies an inspection priority area — it does not identify which individual roofs, if any, sustained damage.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$180K
Potential roof exposure — 15 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Claim window
August 2028
Claims from this storm can typically be filed until around August 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 $3 on top of the $150 plan.
