Evidence / storm surfaces
How Holyoke saw the hail — from two instruments
Two instruments, one storm: NEXRAD logs the point signatures it detected overhead, while the estimated-size surface models how large the hail aloft could have grown. Agreement between them is not guaranteed — the gaps are where the model ran ahead of, or behind, the detections.
Radar signature field NEXRAD's hail signatures for this storm: the spots the radar detected from above. A detection overhead is not the same thing as a confirmed stone below.
Estimated size field Radar-estimated maximum hail size across the swath, modeled from radar aloft. It reflects the biggest stone the storm could support, which may differ from what actually fell.
The storm in context
Where Jun 30, 2026 sits in Holyoke's hail record.
This was Holyoke's 6th recorded hail day, arriving 6 days after the Jun 24, 2026 storm. By severity it ranks 4th of the 13 storms we have logged here. Radar put the day's largest stone over Holyoke at 1.75" — the largest NEXRAD radar signature.
The Jun 30, 2026 convective day was bigger than Holyoke: the same system put hail over 720 other tracked cities, 27 of them in Colorado. Nearest: Champion (16 miles east, up to 1.75"); Yuma (21 miles southwest, up to 0"); Haxtun (22 miles west, up to 0").

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.
The National Weather Service logged no spotter reports for this storm over Holyoke. That absence is ordinary — filing a report takes a person on the spot who saw the hail and phoned it in. What stands as the record for this date is the radar above, which caught the storm regardless.
High damage potential
What 1.75" hail means for Holyoke roofs.
Hail around an inch and a half is capable of cracking shingles, stripping granules, and denting gutters, vents, and siding. Risk is usually greatest near the strongest radar signal, but property-level damage still requires an on-site inspection.
