Evidence / storm surfaces

How Caldwell saw the hail — from two instruments

Aug 6, 2026 · Caldwell, KS

Two instruments, one storm: NEXRAD logs the point signatures it detected overhead, while the estimated-size surface models how large the hail aloft could have grown. Agreement between them is not guaranteed — the gaps are where the model ran ahead of, or behind, the detections.

Radar-estimated hail size Surface resolved
Radar-estimated hail-size map of the storm over Caldwell, KS on Aug 6, 2026 Estimated size field

Radar-estimated maximum hail size across the swath, modeled from radar aloft. It reflects the biggest stone the storm could support, which may differ from what actually fell.

Max size 1.25"

Only the radar-estimated size surface resolved for Aug 6, 2026 — this storm produced no NEXRAD point detections over Caldwell, so there is one map to show, not two.

The storm in context

Where Aug 6, 2026 sits in Caldwell's hail record.

This was Caldwell's 18th recorded hail day, arriving 26 days after the Jul 11, 2026 storm. By severity it ranks 11th of the 18 storms we have logged here. Radar put the day's largest stone over Caldwell at 1.25" — radar-estimated size aloft.

The Aug 6, 2026 convective day was bigger than Caldwell: the same system put hail over 461 other tracked cities, 63 of them in Kansas. Nearest: Medford (14 miles south, up to 1.25"); Wakita (22 miles southwest, up to 0.75"); Pond Creek (27 miles southwest, up to 1.5").

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

No reports filed with the NWS

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 Caldwell, 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 1.25" hail means for Caldwell 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.

140 homes × $12,000 avg. claim

Potential roof exposure

$1.7M

Potential roof exposure — 140 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

Close just 0.5% of the 140 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.

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 7, 2026.
