Evidence / storm surfaces
How Guffey saw the hail — from two instruments
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.
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.
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 May 28, 2026 sits in Guffey's hail record.
This was Guffey's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 4th of the 7 storms we have logged here. Radar put the day's largest stone over Guffey at 0.75" — the largest NEXRAD radar signature.
The May 28, 2026 convective day was bigger than Guffey: the same system put hail over 198 other tracked cities, 15 of them in Colorado. Nearest: Lake George (17 miles north, up to 1"); Woodland Park (30 miles northeast, up to 0.5"); Sedalia (35 miles northeast, up to 0.75").

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 Guffey 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.
Near the severe threshold
What 0.75" hail means for Guffey roofs.
A signal this size sits near the National Weather Service severe threshold. Aging shingles and soft metals such as vents, flashing, and gutters may be more vulnerable; roof age, wind, and material condition all matter, and only an inspection can confirm damage.
