Evidence / storm surfaces
How Oswego saw the hail — from two instruments
Two instruments, one storm: NEXRAD logs the point signatures it detected overhead, while the estimated-size surface models how large the hail aloft could have grown. Agreement between them is not guaranteed — the gaps are where the model ran ahead of, or behind, the detections.
Radar signature field NEXRAD's hail signatures for this storm: the spots the radar detected from above. A detection overhead is not the same thing as a confirmed stone below.
Estimated size field Radar-estimated maximum hail size across the swath, modeled from radar aloft. It reflects the biggest stone the storm could support, which may differ from what actually fell.
The storm in context
Where Apr 28, 2026 sits in Oswego's hail record.
This was Oswego's 5th recorded hail day, arriving 2 days after the Apr 26, 2026 storm. By severity it ranks 6th of the 12 storms we have logged here. Radar put the day's largest stone over Oswego at 1.5" — the largest NEXRAD radar signature.
The Apr 28, 2026 convective day was bigger than Oswego: the same system put hail over 724 other tracked cities, 13 of them in Kansas. Nearest: Parsons (9 miles northwest, up to 1.5"); Cherokee (11 miles east, up to 1.75"); Saint Paul (11 miles north, 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.
For this storm over Oswego, 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.
High damage potential
What 1.5" hail means for Oswego roofs.
Hail around an inch and a half is capable of cracking shingles, stripping granules, and denting gutters, vents, and siding. Risk is usually greatest near the strongest radar signal, but property-level damage still requires an on-site inspection.
