Evidence / storm surfaces
How Geraldine 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 Geraldine's hail record.
This was Geraldine's 2nd recorded hail day, arriving 15 days after the May 13, 2026 storm. By severity it ranks 5th of the 7 storms we have logged here. Radar put the day's largest stone over Geraldine at 1" — the largest NEXRAD radar signature.
The May 28, 2026 convective day was bigger than Geraldine: the same system put hail over 198 other tracked cities, 43 of them in Montana. Nearest: Denton (22 miles east, up to 1.75"); Big Sandy (33 miles northeast, up to 1.25"); Stanford (35 miles south, up to 1.25").

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 Geraldine 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.
Damage-capable hail signal
What 1" hail means for Geraldine roofs.
Quarter-size and larger hail can bruise asphalt mats, remove granules, and dent exposed soft metal. The mapped footprint identifies an inspection priority area — it does not identify which individual roofs, if any, sustained damage.
