Evidence / storm surfaces
How Caldwell 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.
Estimated size field The modeled maximum hail size across the swath, derived from radar aloft — the largest stone the storm could have supported, which is not necessarily what reached the ground.
Only the radar-estimated size surface resolved for May 18, 2026 — this storm produced no NEXRAD point detections over Caldwell, so there is one map to show, not two.
The storm in context
Where May 18, 2026 sits in Caldwell's hail record.
This was Caldwell's 7th recorded hail day, arriving 25 days after the Apr 23, 2026 storm. By severity it ranks 6th of the 18 storms we have logged here. Radar put the day's largest stone over Caldwell at 1.75" — radar-estimated size aloft.
The May 18, 2026 convective day was bigger than Caldwell: the same system put hail over 726 other tracked cities, 258 of them in Kansas. Nearest: Milan (10 miles north, up to 2"); Argonia (12 miles northwest, up to 2.5"); Mayfield (19 miles northeast, up to 1.75").
These maps are stills. In the app this date is one of 18 Caldwell 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.
The National Weather Service logged no spotter reports for this storm over Caldwell. 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.
High damage potential
What 1.75" hail means for Caldwell roofs.
Hail around an inch and a half is capable of cracking shingles, stripping granules, and denting gutters, vents, and siding. Risk is usually greatest near the strongest radar signal, but property-level damage still requires an on-site inspection.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$24M
Potential roof exposure — 2,032 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 10 jobs
- Illustrative work
- ~$150K
Close just 0.5% of the 2,032 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 $427 on top of the $150 plan.
