Hail in Calhan · Jul 28, 2026
NEXRAD logged 117 hail signatures up to 3.5"; the estimated-size surface reached 1.75" aloft. At 3.5" — baseball — this is a severe hail signal associated with roof damage. Open it on the live map to see the swath over the streets.

Evidence / storm surfaces
How Calhan saw the hail — from two instruments
Jul 28, 2026 · Calhan, 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.
NEXRAD radar signatures Surface resolved
Radar signature field Where NEXRAD flagged hail as the storm passed — point signatures from the radar, which indicate hail overhead rather than confirm what landed.

Radar-estimated hail size Surface resolved
Estimated size field The modeled maximum hail size across the swath, derived from radar aloft — the largest stone the storm could have supported, which is not necessarily what reached the ground.

The storm in context
Where Jul 28, 2026 sits in Calhan's hail record.
This was Calhan's 15th recorded hail day, arriving 6 days after the Jul 22, 2026 storm. By severity it ranks 1st of the 23 storms we have logged here. Radar put the day's largest stone over Calhan at 3.5" — the largest NEXRAD radar signature.
The Jul 28, 2026 convective day was bigger than Calhan: the same system put hail over 686 other tracked cities, 84 of them in Colorado. Nearest: Kiowa (11 miles north, up to 1"); Elbert (13 miles west, up to 2.25"); Franktown (22 miles west, up to 1.5").
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.

Severe hail signal
What 3.5" hail means for Calhan 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.

Roofing exposure
What this storm is worth to a roofer.
1,100 homes × $12,000 avg. claim
Potential roof exposure

Potential roof exposure — 1,100 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

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.
