Evidence / storm surfaces
How Oswego saw the hail — from two instruments
The maps here read the same storm from two angles — point detections from NEXRAD, and modeled hail size aloft. Where the two disagree is informative: it marks where estimated size outran the signatures, or trailed them.
The modeled maximum hail size across the swath, derived from radar aloft — the largest stone the storm could have supported, which is not necessarily what reached the ground.
Only the radar-estimated size surface resolved for Sep 20, 2026 — this storm produced no NEXRAD point detections over Oswego, so there is one map to show, not two.
The storm in context
Where Sep 20, 2026 sits in Oswego's hail record.
This was Oswego's 13th recorded hail day, arriving 8 days after the Sep 12, 2026 storm. By severity it ranks 10th of the 13 storms we have logged here. Radar put the day's largest stone over Oswego at 0.75" — radar-estimated size aloft.
The Sep 20, 2026 convective day was bigger than Oswego: the same system put hail over 253 other tracked cities, 3 of them in Kansas. Nearest: Mc Cune (13 miles northeast, up to 0.5"); Baxter Springs (24 miles southeast, up to 0.5"); Galena (28 miles east, up to 0.5").
These maps are stills. In the app this date is one of 13 Oswego storm dates on a live map — both surfaces, the reports, and a replay — and the same map is where you draw the swath. This page rebuilds nightly.
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 Oswego. 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 Oswego 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.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$2.1M
Potential roof exposure — 175 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 1 job
- Illustrative work
- ~$15K
Close just 0.5% of the 175 homes in this footprint at the average $15,000 roof job. Illustrative math, not a projection — your results depend on your outreach and how the market responds.
Claim window
September 2028
Claims from this storm can typically be filed until around September 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.
Names and phones for every home in the footprint: at most $37 on top of the $150 plan.
