Evidence / storm surfaces
How Tucson 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.
Estimated size field Radar-estimated hail size over the swath. The model reports the biggest stone the storm could sustain in the air; what actually fell may have been smaller.
The storm in context
Where Jun 25, 2026 sits in Tucson's hail record.
This was Tucson's 2nd recorded hail day, arriving 8 days after the Jun 17, 2026 storm. By severity it ranks 16th of the 18 storms we have logged here. Radar put the day's largest stone over Tucson at 0" — radar-estimated size aloft.
The Jun 25, 2026 convective day was bigger than Tucson: the same system put hail over 395 other tracked cities, 8 of them in Arizona. Nearest: Hereford (66 miles southeast, up to 0.5"); Mc Neal (74 miles southeast, up to 0.5"); Winslow (187 miles north, up to 0.5").
These maps are stills. In the app this date is one of 18 Tucson 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.
For this storm over Tucson, the NWS report log is empty — a common outcome, since ground reports only happen when someone witnesses the hail and takes the time to call it in. The detection record for the date lives in the radar maps above.
Below the severe threshold
What 0" hail means for Tucson 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.
