Evidence / storm surfaces
How Campbell 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.
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.
Only the radar-estimated size surface resolved for Aug 21, 2026 — this storm produced no NEXRAD point detections over Campbell, so there is one map to show, not two.
The storm in context
Where Aug 21, 2026 sits in Campbell's hail record.
This was Campbell's 9th recorded hail day, arriving 27 days after the Jul 25, 2026 storm. By severity it ranks 7th of the 9 storms we have logged here. Radar put the day's largest stone over Campbell at 0.75" — radar-estimated size aloft.
The Aug 21, 2026 convective day was bigger than Campbell: the same system put hail over 659 other tracked cities, 38 of them in Nebraska. Nearest: Smith Center (21 miles south, up to 0.75"); Esbon (23 miles southeast, up to 0.5"); Hastings (26 miles northeast, up to 0.5").

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.
For this storm over Campbell, the NWS report log is empty — a common outcome, since ground reports only happen when someone witnesses the hail and takes the time to call it in. The detection record for the date lives in the radar maps above.
Near the severe threshold
What 0.75" hail means for Campbell 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.
