Evidence / storm surfaces
How South Haven 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 Aug 21, 2026 — this storm produced no NEXRAD point detections over South Haven, so there is one map to show, not two.
The storm in context
Where Aug 21, 2026 sits in South Haven's hail record.
This was South Haven's 17th recorded hail day, arriving 41 days after the Jul 11, 2026 storm. By severity it ranks 15th of the 17 storms we have logged here. Radar put the day's largest stone over South Haven at 0.5" — radar-estimated size aloft.
The Aug 21, 2026 convective day was bigger than South Haven: the same system put hail over 659 other tracked cities, 30 of them in Kansas. Nearest: Ponca City (28 miles south, up to 0.5"); Conway Springs (30 miles north, up to 0.75"); Cheney (47 miles northwest, up to 0.75").
These maps are stills. In the app this date is one of 17 South Haven 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 South Haven 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 South Haven 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
$1.2M
Potential roof exposure — 102 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 1 job
- Illustrative work
- ~$15K
Close just 0.5% of the 102 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
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 $21 on top of the $150 plan.
