How Alpine saw the hail — from two instruments
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
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.
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 11 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 (66 miles south, up to 1"); Midland (144 miles northeast, up to 0.5"); Andrews (149 miles northeast, up to 0.5").
These maps are stills from Alpine's May 20, 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 Altuda — beyond Alpine itself.
What 1.5" hail means for Alpine roofs
At an inch and a half, hail cracks shingles, strips granules down to the mat, and dents gutters, vents, and siding. A footprint like this typically produces a wave of insurance claims — and the contractor who reaches the homeowner first usually gets the inspection.
What this storm is worth to a roofer
$1.4M
Potential roof exposure — 119 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

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.
