Evidence / storm surfaces

How Crookston saw the hail — from two instruments

Aug 21, 2026 · Crookston, NE

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
Radar-estimated hail-size map of the storm over Crookston, NE on Aug 21, 2026 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 1.25"

Only the radar-estimated size surface resolved for Aug 21, 2026 — this storm produced no NEXRAD point detections over Crookston, so there is one map to show, not two.

The storm in context

Where Aug 21, 2026 sits in Crookston's hail record.

This was Crookston's 13th recorded hail day, arriving 4 days after the Aug 17, 2026 storm. By severity it ranks 8th of the 14 storms we have logged here. Radar put the day's largest stone over Crookston at 1.25" — radar-estimated size aloft.

These maps are stills. In the app this date is one of 14 Crookston 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 Crookston, 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 Crookston 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.

1,078 homes × $12,000 avg. claim

Potential roof exposure

$13M

Potential roof exposure — 1,078 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed 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 28, 2026.
