Evidence / storm surfaces

How Calhan saw the hail — from two instruments

Aug 22, 2026 · Calhan, CO

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 Surface resolved
Radar-estimated hail-size map of the storm over Calhan, CO on Aug 22, 2026 Estimated size field

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"

Only the radar-estimated size surface resolved for Aug 22, 2026 — this storm produced no NEXRAD point detections over Calhan, so there is one map to show, not two.

The storm in context

Where Aug 22, 2026 sits in Calhan's hail record.

This was Calhan's 21st recorded hail day, arriving 3 days after the Aug 19, 2026 storm. By severity it ranks 7th of the 23 storms we have logged here. Radar put the day's largest stone over Calhan at 1" — radar-estimated size aloft.

The Aug 22, 2026 convective day was bigger than Calhan: the same system put hail over 501 other tracked cities, 20 of them in Colorado. Nearest: Bennett (29 miles north, up to 1.5"); Watkins (32 miles northwest, up to 1.75"); Castle Rock (35 miles northwest, up to 0.75").

These maps are stills. In the app this date is one of 23 Calhan 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.

Nobody on the ground filed a report over Calhan for this date, which says more about who was watching than about the storm: spotter reports only exist where there is an observer. The radar surfaces above carry the evidence for this one.

Damage-capable hail signal

What 1" hail means for Calhan 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.

971 homes × $12,000 avg. claim

Potential roof exposure

$12M

Potential roof exposure — 971 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

Close just 0.5% of the 971 homes in this footprint at the average $15,000 roof job. Illustrative math, not a projection — your results depend on your outreach and how the market responds.

Claim window

August 2028

Claims from this storm can typically be filed until around August 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 $204 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 Aug 28, 2026.
