Evidence / storm surfaces
How Littleton saw the hail — from two instruments
Aug 14, 2026 · Littleton, 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 14, 2026 sits in Littleton's hail record.
This was Littleton's 4th recorded hail day, arriving 51 days after the Jun 24, 2026 storm. By severity it ranks 2nd of the 6 storms we have logged here. Radar put the day's largest stone over Littleton at 1.25" — radar-estimated size aloft.
The Aug 14, 2026 convective day was bigger than Littleton: the same system put hail over 316 other tracked cities, 36 of them in Colorado. Nearest: Castle Rock (13 miles southeast, up to 0.75"); Denver (14 miles north, up to 1.25"); Bailey (17 miles southwest, up to 0.75").
These maps are stills. In the app this date is one of 6 Littleton 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 Littleton 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.

28,182 homes × $12,000 avg. claim
Potential roof exposure
$338M
Potential roof exposure — 28,182 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

Close just 0.5% of the 28,182 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.

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 23, 2026.
