Two ways to read the storm

How Parshall 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.

Radar-estimated maximum hail size across the swath, modeled from radar aloft. It reflects the biggest stone the storm could support, which may differ from what actually fell.

Where Jul 21, 2026 sits in Parshall's hail record

This was Parshall's 2nd recorded hail day, arriving 13 days after the Jul 8, 2026 storm. By severity it ranks 2nd of the 3 storms we have logged here. Radar put the day's largest stone over Parshall at 0.75" — the largest NEXRAD radar signature.

The Jul 21, 2026 convective day was bigger than Parshall: the same system put hail over 703 other tracked cities, 22 of them in Colorado. Nearest: Kremmling (14 miles north, up to 0.75"); Georgetown (28 miles southeast, up to 0.5"); Silver Plume (28 miles southeast, up to 0.5").

These maps are stills from Parshall's Jul 21, 2026 storm. In the Overview app the same surfaces are live — radar updating in real time, radar-estimated hail size as it forms, and NWS spotter reports pinned where they're filed — with a radar replay you can scrub back over any past day.

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.

No ground reports were filed with the National Weather Service for this storm over Parshall. That is common: a report depends on someone being there to see it and take the time to call it in. The radar surfaces above are the record here — the storm was detected from above even though no one on the ground logged it.

Near the severe threshold

What 0.75" hail means for Parshall roofs

Hail this size sits right at the edge of the National Weather Service severe threshold. Newer roofs usually shrug it off, but aging or already-worn shingles can bruise, and soft metals — vents, flashing, gutters — often show the first dents.

What this storm is worth to a roofer

$12K

Potential roof exposure — 1 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Claims from this storm can typically be filed until around July 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.

Other storms in Parshall

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.
