Evidence / storm surfaces
How Austin saw the hail — from two instruments
Each storm gets two readings: the radar signatures NEXRAD recorded as the cells passed overhead, and a modeled estimate of hail size in the air. They are independent surfaces, so a mismatch between them is expected — and worth reading.
Radar signature field The point detections NEXRAD recorded overhead. Each signature marks where the radar saw hail aloft — it is a detection, not a stone measured on the ground.
Only the NEXRAD radar-signature surface resolved for Apr 23, 2026 — the estimated-size swath had no hail signal to model for this storm, so there is one map to show, not two.
The storm in context
Where Apr 23, 2026 sits in Austin's hail record.
This was Austin's 5th recorded hail day, arriving 6 days after the Apr 17, 2026 storm. By severity it ranks 11th of the 13 storms we have logged here. Radar put the day's largest stone over Austin at 0" — radar-estimated size aloft.
The Apr 23, 2026 convective day was bigger than Austin: the same system put hail over 703 other tracked cities, 58 of them in Minnesota. Nearest: Glenville (12 miles southwest, up to 1"); Albert Lea (15 miles west, up to 1"); Emmons (28 miles west, up to 1").
These maps are stills. In the app this date is one of 13 Austin 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 Austin. 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.
Below the severe threshold
What 0" hail means for Austin roofs.
Radar signals under three-quarters of an inch stay below the National Weather Service severe threshold and generally indicate lower roof risk. Older or already-worn materials can still show effects, but radar alone cannot determine whether a specific roof was damaged.
