How Missoula 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.
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.
Where May 28, 2026 sits in Missoula's hail record
This was Missoula's 2nd recorded hail day, arriving 1 day after the May 27, 2026 storm. By severity it ranks 1st of the 2 storms we have logged here. Radar put the day's largest stone over Missoula at 1" — the largest NEXRAD radar signature.
The May 28, 2026 convective day was bigger than Missoula: the same system put hail over 198 other tracked cities, 43 of them in Montana. Nearest: Florence (7 miles south, up to 1"); Stevensville (23 miles southeast, up to 0.5"); Clinton (25 miles southeast, up to 1.75").
These maps are stills from Missoula's May 28, 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.
Nobody on the ground filed a report over Missoula 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.
What 1" hail means for Missoula roofs
Quarter-size and larger hail is where asphalt shingle damage starts in earnest: bruised mats and granule loss that homeowners can't see from the ground. Most people inside the footprint won't know their roof was hit until someone inspects it.
