Two ways to read the storm

How Commerce City saw the hail — from two instruments

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.

Only the NEXRAD radar-signature surface resolved for May 17, 2026 — the estimated-size swath had no hail signal to model for this storm, so there is one map to show, not two.

Ground reports

What people on the ground reported

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 Commerce City, 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.

Below the severe threshold

What 0" hail means for Commerce City roofs

Hail under three-quarters of an inch stays below the National Weather Service severe threshold and rarely breaks shingles outright. But repeated small-hail events accelerate granule loss and shorten roof life — on older roofs, it's still worth a conversation.

Other storms in Commerce City

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 surfaces are detections and estimates, not confirmed damage. Last updated Aug 3, 2026.
