Evidence / storm surfaces

How Nogales saw the hail — from two instruments

Aug 19, 2026 · Nogales, AZ

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.

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.

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 Aug 19, 2026 sits in Nogales's hail record.

This was Nogales's 8th recorded hail day, arriving 8 days after the Aug 11, 2026 storm. By severity it ranks 1st of the 12 storms we have logged here. Radar put the day's largest stone over Nogales at 1.5" — radar-estimated size aloft.

The Aug 19, 2026 convective day was bigger than Nogales: the same system put hail over 496 other tracked cities, 25 of them in Arizona. Nearest: Rio Rico (10 miles north, up to 1.5"); Sonoita (27 miles northeast, up to 1.25"); Sahuarita (41 miles north, up to 0.75").

These maps are stills. In the app this date is one of 12 Nogales 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.

Timing and place names from NOAA ground reports

Reports came from Rio Rico — beyond Nogales itself.

High damage potential

What 1.5" hail means for Nogales 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.

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 Aug 27, 2026.
