Evidence / storm surfaces

How Deer Trail saw the hail — from two instruments

Aug 15, 2026 · Deer Trail, 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 Aug 15, 2026 sits in Deer Trail's hail record.

This was Deer Trail's 11th recorded hail day, arriving 1 day after the Aug 14, 2026 storm. By severity it ranks 12th of the 12 storms we have logged here. Radar put the day's largest stone over Deer Trail at 0.5" — radar-estimated size aloft.

The Aug 15, 2026 convective day was bigger than Deer Trail: the same system put hail over 188 other tracked cities, 30 of them in Colorado. Nearest: Byers (7 miles north, up to 0.5"); Calhan (30 miles south, up to 0.5"); Parker (38 miles west, up to 1.25").

These maps are stills. In the app this date is one of 12 Deer Trail 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 Deer Trail 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.

Below the severe threshold

What 0.5" hail means for Deer Trail roofs.

Radar signals under three-quarters of an inch stay below the National Weather Service severe threshold and generally indicate lower roof risk. Older or already-worn materials can still show effects, but radar alone cannot determine whether a specific roof was damaged.

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 27, 2026.
