Evidence / storm surfaces
How Gardner saw the hail — from two instruments
Sep 15, 2026 · Gardner, KS
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-estimated hail size Surface resolved
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.
Max size
0.75"
Only the radar-estimated size surface resolved for Sep 15, 2026 — this storm produced no NEXRAD point detections over Gardner, so there is one map to show, not two.
The storm in context
Where Sep 15, 2026 sits in Gardner's hail record.
This was Gardner's 8th recorded hail day, arriving 37 days after the Aug 9, 2026 storm. By severity it ranks 4th of the 8 storms we have logged here. Radar put the day's largest stone over Gardner at 0.75" — radar-estimated size aloft.
The Sep 15, 2026 convective day was bigger than Gardner: the same system put hail over 169 other tracked cities, 15 of them in Kansas. Nearest: Edgerton (7 miles south, up to 1"); Rantoul (15 miles south, up to 0.75"); Greeley (28 miles south, up to 0.5").
These maps are stills. In the app this date is one of 8 Gardner 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.

Near the severe threshold
What 0.75" hail means for Gardner 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.

A storm day here is a convective day — it runs from noon to noon
UTC, so late-night hail is grouped with the afternoon storm that
spawned it rather than split across two calendar dates. Ground
reports are public-domain observations from the NOAA Storm
Prediction Center. Radar tells you where to look. Only an inspection confirms damage at an address. Last updated Sep 16, 2026.
