Hail in Coldwater · Sep 12, 2026
The estimated-size surface reached 2.25" aloft; NEXRAD logged no point detections over Coldwater that day. At 2.25" — tennis ball — this is a severe hail signal associated with roof damage. Open it on the live map to see the swath over the streets.

Evidence / storm surfaces
How Coldwater 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 Sep 12, 2026 — this storm produced no NEXRAD point detections over Coldwater, so there is one map to show, not two.
The storm in context
Where Sep 12, 2026 sits in Coldwater's hail record.
This was Coldwater's 11th recorded hail day, arriving 29 days after the Aug 14, 2026 storm. By severity it ranks 1st of the 11 storms we have logged here. Radar put the day's largest stone over Coldwater at 2.25" — radar-estimated size aloft.
The Sep 12, 2026 convective day was bigger than Coldwater: the same system put hail over 354 other tracked cities, 113 of them in Kansas. Nearest: Wilmore (9 miles northeast, up to 1.75"); Protection (11 miles southwest, up to 2.25"); Sun City (22 miles northeast, up to 1.25").
These maps are stills. In the app this date is one of 11 Coldwater 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.

Storm forensics
How the storm moved
Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.
Reports came from Wilmore — beyond Coldwater itself.
Severe hail signal
What 2.25" hail means for Coldwater roofs.
Two-inch-plus hail is capable of puncturing shingles, breaking skylights or windows, and heavily denting soft materials. The strongest radar bands warrant prompt inspection, but neither the signal nor the footprint confirms damage at a specific address.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$9.9M
Potential roof exposure — 823 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 4 jobs
- Illustrative work
- ~$60K
Close just 0.5% of the 823 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
September 2028
Claims from this storm can typically be filed until around September 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 $173 on top of the $150 plan.
