How Shamrock saw the hail — from two instruments
Mar 31, 2026 · Shamrock, TX
The maps here read the same storm from two angles — point detections from NEXRAD, and modeled hail size aloft. Where the two disagree is informative: it marks where estimated size outran the signatures, or trailed them.
NEXRAD radar signatures Surface resolved
Radar signature field Where NEXRAD flagged hail as the storm passed — point signatures from the radar, which indicate hail overhead rather than confirm what landed.

Radar-estimated hail size Surface resolved
Estimated size field The modeled maximum hail size across the swath, derived from radar aloft — the largest stone the storm could have supported, which is not necessarily what reached the ground.

The storm in context
Where Mar 31, 2026 sits in Shamrock's hail record.
This was Shamrock's 3rd recorded hail day, arriving 1 day after the Mar 30, 2026 storm. By severity it ranks 1st of the 11 storms we have logged here. Radar put the day's largest stone over Shamrock at 2.75" — the largest NEXRAD radar signature.
The Mar 31, 2026 convective day was bigger than Shamrock: the same system put hail over 522 other tracked cities, 16 of them in Texas. Nearest: Wellington (24 miles southeast, up to 2.25"); Erick (25 miles east, up to 1"); Vinson (31 miles southeast, up to 2.25").
These maps are stills. In the app this date is one of 11 Shamrock 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.

Severe hail signal
What 2.75" hail means for Shamrock roofs.
Two-inch-plus hail is capable of puncturing shingles, breaking skylights or windows, and heavily denting soft materials. The strongest radar bands warrant prompt inspection, but neither the signal nor the footprint confirms damage at a specific address.

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 16, 2026.
