Evidence / storm surfaces
How De Kalb 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.
Estimated size field 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 21, 2026 — this storm produced no NEXRAD point detections over De Kalb, so there is one map to show, not two.
The storm in context
Where Sep 21, 2026 sits in De Kalb's hail record.
This was De Kalb's 9th recorded hail day, arriving 67 days after the Jul 16, 2026 storm. By severity it ranks 8th of the 9 storms we have logged here. Radar put the day's largest stone over De Kalb at 0.75" — radar-estimated size aloft.
The Sep 21, 2026 convective day was bigger than De Kalb: the same system put hail over 498 other tracked cities, 60 of them in Texas. Nearest: Haworth (18 miles northeast, up to 0.75"); Douglassville (36 miles southeast, up to 1"); Lockesburg (37 miles east, 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 De Kalb, 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 De Kalb 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.
