Evidence / storm surfaces
How Alpine saw the hail — from two instruments
May 20, 2026 · Alpine, 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.
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.
Max size
1.5"
Only the radar-estimated size surface resolved for May 20, 2026 — this storm produced no NEXRAD point detections over Alpine, so there is one map to show, not two.
The storm in context
Where May 20, 2026 sits in Alpine's hail record.
This was Alpine's 2nd recorded hail day, arriving 51 days after the Mar 30, 2026 storm. By severity it ranks 1st of the 14 storms we have logged here. Radar put the day's largest stone over Alpine at 1.5" — radar-estimated size aloft.
The May 20, 2026 convective day was bigger than Alpine: the same system put hail over 109 other tracked cities, 24 of them in Texas. Nearest: Terlingua (53 miles south, up to 1"); Midland (154 miles northeast, up to 0.5"); Andrews (161 miles northeast, up to 0.5").
These maps are stills. In the app this date is one of 14 Alpine 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.

High damage potential
What 1.5" hail means for Alpine roofs.
Hail around an inch and a half is capable of cracking shingles, stripping granules, and denting gutters, vents, and siding. Risk is usually greatest near the strongest radar signal, but property-level damage still requires an on-site inspection.

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 13, 2026.
