How Chandler saw the hail — from two instruments

Oct 20, 2026 · Chandler, 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 map of the storm over Chandler, AZ on Oct 20, 2026 — 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 1.25"

Only the radar-estimated size surface resolved for Oct 20, 2026 — this storm produced no NEXRAD point detections over Chandler, so there is one map to show, not two.

The storm in context

Where Oct 20, 2026 sits in Chandler's hail record.

This was Chandler's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 1st of the 1 storms we have logged here. Radar put the day's largest stone over Chandler at 1.25" — radar-estimated size aloft.

The Oct 20, 2026 convective day was bigger than Chandler: the same system put hail over 19 other tracked cities, 18 of them in Arizona. Nearest: Laveen (12 miles southwest, up to 1.25"); Mesa (14 miles northeast, up to 1.75"); Fort Mcdowell (34 miles northeast, up to 2").

These maps are stills. In the app this date is one of 1 Chandler storm date 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.

Damage-capable hail signal

What 1.25" hail means for Chandler roofs.

Quarter-size and larger hail can bruise asphalt mats, remove granules, and dent exposed soft metal. The mapped footprint identifies an inspection priority area — it does not identify which individual roofs, if any, sustained damage.

Roofing exposure

What this storm is worth to a roofer.

28,521 homes × $12,000 avg. claim

Potential roof exposure

$342M

Potential roof exposure — 28,521 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

Illustrative jobs: 143 jobs

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 Oct 21, 2026.
