Evidence / storm surfaces
How Overland Park saw the hail — from two instruments
Aug 21, 2026 · Overland Park, KS
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-estimated hail size Surface resolved
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.
Max size
1"
Only the radar-estimated size surface resolved for Aug 21, 2026 — this storm produced no NEXRAD point detections over Overland Park, so there is one map to show, not two.
The storm in context
Where Aug 21, 2026 sits in Overland Park's hail record.
This was Overland Park's 6th recorded hail day, arriving 82 days after the May 31, 2026 storm. By severity it ranks 3rd of the 6 storms we have logged here. Radar put the day's largest stone over Overland Park at 1" — radar-estimated size aloft.
The Aug 21, 2026 convective day was bigger than Overland Park: the same system put hail over 659 other tracked cities, 30 of them in Kansas. Nearest: Belton (9 miles southeast, up to 0.75"); Shawnee (13 miles northwest, up to 0.75"); Peculiar (18 miles southeast, up to 1").
These maps are stills. In the app this date is one of 6 Overland Park 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.

Damage-capable hail signal
What 1" hail means for Overland Park 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.
28,846 homes × $12,000 avg. claim
Potential roof exposure
$346M
Potential roof exposure — 28,846 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

Close just 0.5% of the 28,846 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.

A storm day here is a convective day — it runs from noon to noon
UTC, so late-night hail is grouped with the afternoon storm that
spawned it rather than split across two calendar dates. Ground
reports are public-domain observations from the NOAA Storm
Prediction Center. Radar tells you where to look. Only an inspection confirms damage at an address. Last updated Aug 22, 2026.
