How Colo 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.
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.
Only the NEXRAD radar-signature surface resolved for Apr 3, 2026 — the estimated-size swath had no hail signal to model for this storm, so there is one map to show, not two.
Where Apr 3, 2026 sits in Colo's hail record
This was Colo's 2nd recorded hail day, arriving 28 days after the Mar 6, 2026 storm. By severity it ranks 5th of the 7 storms we have logged here. Radar put the day's largest stone over Colo at 0.5" — the largest NEXRAD radar signature.
The Apr 3, 2026 convective day was bigger than Colo: the same system put hail over 367 other tracked cities, 36 of them in Iowa. Nearest: Maxwell (15 miles south, up to 0.5"); Story City (21 miles northwest, up to 0"); Newton (24 miles southeast, up to 0").
These maps are stills from Colo's Apr 3, 2026 storm. In the Overview app the same surfaces are live — radar updating in real time, radar-estimated hail size as it forms, and NWS spotter reports pinned where they're filed — with a radar replay you can scrub back over any past day.
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 Colo. 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.
What 0.5" hail means for Colo roofs
Hail under three-quarters of an inch stays below the National Weather Service severe threshold and rarely breaks shingles outright. But repeated small-hail events accelerate granule loss and shorten roof life — on older roofs, it's still worth a conversation.
