Evidence / storm surfaces

How Tucson saw the hail — from two instruments

Sep 14, 2026 · Tucson, AZ

We map this storm two ways: the NEXRAD radar signatures the storm produced overhead, and the radar-estimated size of the hail in the air. The two surfaces don’t have to match — where they diverge is where estimated size aloft ran ahead of, or behind, what the signatures caught.

Radar-estimated hail size Surface resolved
Radar-estimated hail-size map of the storm over Tucson, AZ on Sep 14, 2026 Estimated size field

Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.

Max size 0.75"

Only the radar-estimated size surface resolved for Sep 14, 2026 — this storm produced no NEXRAD point detections over Tucson, so there is one map to show, not two.

The storm in context

Where Sep 14, 2026 sits in Tucson's hail record.

This was Tucson's 18th recorded hail day, arriving 2 days after the Sep 12, 2026 storm. By severity it ranks 6th of the 18 storms we have logged here. Radar put the day's largest stone over Tucson at 0.75" — radar-estimated size aloft.

The Sep 14, 2026 convective day was bigger than Tucson: the same system put hail over 110 other tracked cities, 16 of them in Arizona. Nearest: Vail (16 miles southeast, up to 0.75"); Sells (29 miles west, up to 0.5"); Amado (33 miles south, 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.

Near the severe threshold

What 0.75" hail means for Tucson roofs.

A signal this size sits near the National Weather Service severe threshold. Aging shingles and soft metals such as vents, flashing, and gutters may be more vulnerable; roof age, wind, and material condition all matter, and only an inspection can confirm 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 tells you where to look. Only an inspection confirms damage at an address. Last updated Sep 15, 2026.
