Hail in Sterling Jun 30, 2026

Hit 34 days ago

Both radar surfaces caught this storm: NEXRAD logged 0 hail signatures up to 4", and the radar-estimated size reached 3" aloft. At 4" — softball or larger — this is severe, roof-replacing hail: close to every roof inside the footprint becomes a claim candidate.

A tornado was also reported to the National Weather Service during this storm — see the ground reports below.

Two ways to read the storm

How Sterling saw the hail — from two instruments

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.

NEXRAD radar-signature map of the hail storm over Sterling, CO on Jun 30, 2026 — NEXRAD radar signatures — the point detections the storm produced overhead. A signature is where the radar saw hail, not a confirmed stone on the ground.

Severe, roof-replacing hail

What 4" hail means for Sterling roofs

Two-inch-plus hail punctures shingles, breaks skylights and windows, and dents anything soft. In the core of a footprint like this, close to every roof is a candidate for an insurance claim. Speed decides who writes those jobs.
