Evidence / storm surfaces

How Cherokee saw the hail — from two instruments

Apr 21, 2026 · Cherokee, IA

The maps here read the same storm from two angles — point detections from NEXRAD, and modeled hail size aloft. Where the two disagree is informative: it marks where estimated size outran the signatures, or trailed them.

NEXRAD radar signatures Surface resolved
NEXRAD radar-signature map of the hail storm over Cherokee, IA on Apr 21, 2026 Radar signature field

Where NEXRAD flagged hail as the storm passed — point signatures from the radar, which indicate hail overhead rather than confirm what landed.

Max size 1" Detections 0

Only the NEXRAD radar-signature surface resolved for Apr 21, 2026 — the estimated-size swath had no hail signal to model for this storm, so there is one map to show, not two.

The storm in context

Where Apr 21, 2026 sits in Cherokee's hail record.

This was Cherokee's 2nd recorded hail day, arriving 8 days after the Apr 13, 2026 storm. By severity it ranks 16th of the 17 storms we have logged here. Radar put the day's largest stone over Cherokee at 1" — the largest NEXRAD radar signature.

The Apr 21, 2026 convective day was bigger than Cherokee: the same system put hail over 24 other tracked cities, 1 of them in Iowa. Nearest: Lawton (40 miles southwest, up to 0"); Waterman (350 miles east, up to 0.5"); Nashotah (360 miles east, up to 0.5").

These maps are stills. In the app this date is one of 17 Cherokee 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.

Nobody on the ground filed a report over Cherokee 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.

Damage-capable hail signal

What 1" hail means for Cherokee 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.

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 Sep 7, 2026.
