How Shamrock 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.
NEXRAD radar signatures
NEXRAD's hail signatures for this storm: the spots the radar detected from above. A detection overhead is not the same thing as a confirmed stone below.

Where Mar 30, 2026 sits in Shamrock's hail record
This was Shamrock's 2nd recorded hail day, arriving 25 days after the Mar 5, 2026 storm. By severity it ranks 7th of the 9 storms we have logged here. Radar put the day's largest stone over Shamrock at 0.5" — the largest NEXRAD radar signature.
The Mar 30, 2026 convective day was bigger than Shamrock: the same system put hail over 313 other tracked cities, 11 of them in Texas. Nearest: Mclean (23 miles west, up to 0.75"); Wellington (24 miles south, up to 1"); Hollis (35 miles southeast, up to 1").
These maps are stills from Shamrock's Mar 30, 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.
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.

How the storm moved
Reports came from Samnorwood — beyond Shamrock itself.
What 0.5" hail means for Shamrock 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.
What this storm is worth to a roofer
$600K
Potential roof exposure — 50 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage. Claims from this storm can typically be filed until around March 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.

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.
