Evidence / storm surfaces
How Glendo saw the hail — from two instruments
Aug 22, 2026 · Glendo, WY
We map this storm two ways: the NEXRAD radar signatures the storm produced overhead, and the radar-estimated size of the hail in the air. The two surfaces don’t have to match — where they diverge is where estimated size aloft ran ahead of, or behind, what the signatures caught.
NEXRAD radar signatures Surface resolved
Radar signature field NEXRAD radar signatures — the point detections the storm produced overhead. A signature is where the radar saw hail, not a confirmed stone on the ground.

Radar-estimated hail size Surface resolved
Estimated size field Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.

The storm in context
Where Aug 22, 2026 sits in Glendo's hail record.
This was Glendo's 7th recorded hail day, arriving 7 days after the Aug 15, 2026 storm. By severity it ranks 2nd of the 8 storms we have logged here. Radar put the day's largest stone over Glendo at 1.25" — radar-estimated size aloft.
The Aug 22, 2026 convective day was bigger than Glendo: the same system put hail over 501 other tracked cities, 6 of them in Wyoming. Nearest: Wheatland (24 miles south, up to 1.25"); Douglas (26 miles west, up to 1.75"); Lance Creek (33 miles north, up to 1").

Ground reports
What people on the ground reported
1 report 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.

Damage-capable hail signal
What 1.25" hail means for Glendo 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.
49 homes × $12,000 avg. claim
Potential roof exposure
$588K
Potential roof exposure — 49 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
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.
Names and phones for every home in the footprint: at most $10 on top of the $150 plan.

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.
