Evidence / storm surfaces
How Eau Claire 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 9, 2026 — this storm produced no NEXRAD point detections over Eau Claire, so there is one map to show, not two.

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.
No ground reports were filed with the National Weather Service for this storm over Eau Claire. That is common: a report depends on someone being there to see it and take the time to call it in. The radar surfaces above are the record here — the storm was detected from above even though no one on the ground logged it.
Near the severe threshold
What 0.75" hail means for Eau Claire 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.
