Severity
The 7th most severe storm Boone has seen in the last 12 months
Overview's storm severity score weighs hailstone size, homes in the footprint, and ground-truth reports.

Evidence / storm surfaces
How Boone saw the hail — from two instruments
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.
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.
Only the radar-estimated size surface resolved for Aug 19, 2026 — this storm produced no NEXRAD point detections over Boone, so there is one map to show, not two.
The storm in context
Where Aug 19, 2026 sits in Boone's hail record.
This was Boone's 8th recorded hail day, arriving 21 days after the Jul 29, 2026 storm. By severity it ranks 7th of the 8 storms we have logged here. Radar put the day's largest stone over Boone at 0.5" — radar-estimated size aloft.
The Aug 19, 2026 convective day was bigger than Boone: the same system put hail over 496 other tracked cities, 30 of them in Colorado. Nearest: Colorado Springs (31 miles northwest, up to 1"); Rush (40 miles north, up to 1"); Pueblo (41 miles west, up to 1.5").
These maps are stills. In the app this date is one of 8 Boone 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
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 Boone 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 Boone 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.
