How Holyoke saw the hail — from two instruments
Jun 8, 2026 · Holyoke, 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 Jun 8, 2026 sits in Holyoke's hail record.
This was Holyoke's 3rd recorded hail day, arriving 9 days after the May 30, 2026 storm. By severity it ranks 13th of the 13 storms we have logged here. Radar put the day's largest stone over Holyoke at 0" — radar-estimated size aloft.
The Jun 8, 2026 convective day was bigger than Holyoke: the same system put hail over 359 other tracked cities, 49 of them in Colorado. Nearest: Yuma (21 miles southwest, up to 1"); Haxtun (22 miles west, up to 0.5"); Imperial (26 miles east, up to 1").
These maps are stills. In the app this date is one of 13 Holyoke 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
1 report 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.

What 0" hail means for Holyoke 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 16, 2026.
