Evidence / storm surfaces

How Sterling saw the hail — from two instruments

Jul 4, 2026 · Sterling, CO

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.

The storm in context

Where Jul 4, 2026 sits in Sterling's hail record.

This was Sterling's 16th recorded hail day, arriving 1 day after the Jul 3, 2026 storm. By severity it ranks 14th of the 24 storms we have logged here. Radar put the day's largest stone over Sterling at 1.25" — the largest NEXRAD radar signature.

The Jul 4, 2026 convective day was bigger than Sterling: the same system put hail over 2,035 other tracked cities, 38 of them in Colorado. Nearest: Otis (19 miles southeast, up to 3.75"); Merino (21 miles southwest, up to 1"); Snyder (23 miles southwest, 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.

Ground reports

What people on the ground reported

No reports filed with the NWS

These are storm reports filed with the National Weather Service and released through the NOAA Storm Prediction Center — public-domain observations from spotters, the public, and NWS surveys. We quote each one exactly as filed.

No ground reports were filed with the National Weather Service for this storm over Sterling. That is common: a report depends on someone being there to see it and take the time to call it in. The radar surfaces above are the record here — the storm was detected from above even though no one on the ground logged it.

Damage-capable hail signal

What 1.25" hail means for Sterling 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.

25 homes × $12,000 avg. claim

Potential roof exposure

$300K

Potential roof exposure — 25 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

Claim window

July 2028

Claims from this storm can typically be filed until around July 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.

Names and phones for every home in the footprint: at most $5 on top of the $150 plan.

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.
