Evidence / storm surfaces
How Woodrow saw the hail — from two instruments
May 21, 2026 · Woodrow, CO
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
1.5"
Only the radar-estimated size surface resolved for May 21, 2026 — this storm produced no NEXRAD point detections over Woodrow, so there is one map to show, not two.
The storm in context
Where May 21, 2026 sits in Woodrow's hail record.
This was Woodrow's 3rd recorded hail day, arriving 4 days after the May 17, 2026 storm. By severity it ranks 6th of the 18 storms we have logged here. Radar put the day's largest stone over Woodrow at 1.5" — radar-estimated size aloft.
The May 21, 2026 convective day was bigger than Woodrow: the same system put hail over 120 other tracked cities, 20 of them in Colorado. Nearest: Lindon (11 miles east, up to 1.75"); Anton (27 miles east, up to 2"); Byers (27 miles west, up to 0.75").
These maps are stills. In the app this date is one of 18 Woodrow 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.

High damage potential
What 1.5" hail means for Woodrow roofs.
Hail around an inch and a half is capable of cracking shingles, stripping granules, and denting gutters, vents, and siding. Risk is usually greatest near the strongest radar signal, but property-level damage still requires an on-site inspection.

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 27, 2026.
