Evidence / storm surfaces
How Calhan saw the hail — from two instruments
Aug 16, 2026 · Calhan, 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.
NEXRAD radar signatures Surface resolved
Radar signature field 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.

Radar-estimated hail size Surface resolved
Estimated size field Radar-estimated hail size over the swath. The model reports the biggest stone the storm could sustain in the air; what actually fell may have been smaller.

The storm in context
Where Aug 16, 2026 sits in Calhan's hail record.
This was Calhan's 19th recorded hail day, arriving 1 day after the Aug 15, 2026 storm. By severity it ranks 4th of the 23 storms we have logged here. Radar put the day's largest stone over Calhan at 1.25" — radar-estimated size aloft.
The Aug 16, 2026 convective day was bigger than Calhan: the same system put hail over 264 other tracked cities, 22 of them in Colorado. Nearest: Elbert (13 miles west, up to 0.5"); Franktown (22 miles west, up to 0.75"); Ramah (26 miles southeast, up to 1").
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.

Damage-capable hail signal
What 1.25" 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.
358 homes × $12,000 avg. claim
Potential roof exposure

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.
