Evidence / storm surfaces

How Caldwell saw the hail — from two instruments

Jun 20, 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 Jun 20, 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 0.75"

Only the radar-estimated size surface resolved for Jun 20, 2026 — this storm produced no NEXRAD point detections over Caldwell, so there is one map to show, not two.

The storm in context

Where Jun 20, 2026 sits in Caldwell's hail record.

This was Caldwell's 13th recorded hail day, arriving 2 days after the Jun 18, 2026 storm. By severity it ranks 13th of the 18 storms we have logged here. Radar put the day's largest stone over Caldwell at 0.75" — radar-estimated size aloft.

The Jun 20, 2026 convective day was bigger than Caldwell: the same system put hail over 298 other tracked cities, 121 of them in Kansas. Nearest: Milan (10 miles north, up to 0.75"); Argonia (12 miles northwest, up to 0.75"); South Haven (22 miles east, up to 0.75").

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

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.

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.

Near the severe threshold

What 0.75" hail means for Caldwell roofs.

A signal this size sits near the National Weather Service severe threshold. Aging shingles and soft metals such as vents, flashing, and gutters may be more vulnerable; roof age, wind, and material condition all matter, and only an inspection can confirm damage.

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.
