How Sterling saw the hail — from two instruments

Jul 3, 2026 · Sterling, CO

The maps here read the same storm from two angles — point detections from NEXRAD, and modeled hail size aloft. Where the two disagree is informative: it marks where estimated size outran the signatures, or trailed them.

Where NEXRAD flagged hail as the storm passed — point signatures from the radar, which indicate hail overhead rather than confirm what landed.

The storm in context

Where Jul 3, 2026 sits in Sterling's hail record.

This was Sterling's 15th recorded hail day, arriving 1 day after the Jul 2, 2026 storm. By severity it ranks 5th of the 24 storms we have logged here. Radar put the day's largest stone over Sterling at 2.5" — the largest NEXRAD radar signature.

The Jul 3, 2026 convective day was bigger than Sterling: the same system put hail over 1,885 other tracked cities, 35 of them in Colorado. Nearest: Atwood (11 miles south, up to 2.5"); Fleming (18 miles east, up to 1.75"); Sidney (31 miles north, up to 1").

These maps are stills. In the app this date is one of 24 Sterling 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.

Severe hail signal

What 2.5" hail means for Sterling roofs.

Two-inch-plus hail is capable of puncturing shingles, breaking skylights or windows, and heavily denting soft materials. The strongest radar bands warrant prompt inspection, but neither the signal nor the footprint confirms damage at a specific address.

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 6, 2026.
