Evidence / storm surfaces
How Penitas 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 signature field Where NEXRAD flagged hail as the storm passed — point signatures from the radar, which indicate hail overhead rather than confirm what landed.
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 May 10, 2026 sits in Penitas's hail record.
This was Penitas's 3rd recorded hail day, arriving 1 day after the May 9, 2026 storm. By severity it ranks 1st of the 4 storms we have logged here. Radar put the day's largest stone over Penitas at 1.75" — the largest NEXRAD radar signature.
The May 10, 2026 convective day was bigger than Penitas: the same system put hail over 350 other tracked cities, 259 of them in Texas. Nearest: Rio Grande City (23 miles northwest, up to 1"); Falfurrias (64 miles northeast, up to 1"); Freer (100 miles north, up to 0").
These maps are stills. In the app this date is one of 4 Penitas 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.
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.
The National Weather Service logged no spotter reports for this storm over Penitas. That absence is ordinary — filing a report takes a person on the spot who saw the hail and phoned it in. What stands as the record for this date is the radar above, which caught the storm regardless.
High damage potential
What 1.75" hail means for Penitas 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.
