Evidence / storm surfaces
How De Kalb saw the hail — from two instruments
We map this storm two ways: the NEXRAD radar signatures the storm produced overhead, and the radar-estimated size of the hail in the air. The two surfaces don’t have to match — where they diverge is where estimated size aloft ran ahead of, or behind, what the signatures caught.
Estimated size field Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.
Only the radar-estimated size surface resolved for Aug 20, 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 Aug 20, 2026 sits in De Kalb's hail record.
This was De Kalb's 10th recorded hail day, arriving 12 days after the Aug 8, 2026 storm. By severity it ranks 10th of the 10 storms we have logged here. Radar put the day's largest stone over De Kalb at 0.5" — radar-estimated size aloft.
The Aug 20, 2026 convective day was bigger than De Kalb: the same system put hail over 640 other tracked cities, 92 of them in Mississippi. Nearest: Porterville (9 miles east, up to 1"); Lisman (28 miles southeast, up to 0.5"); Macon (30 miles northeast, up to 0.5").
These maps are stills. In the app this date is one of 10 De Kalb 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.
The National Weather Service logged no spotter reports for this storm over De Kalb. That absence is ordinary — filing a report takes a person on the spot who saw the hail and phoned it in. What stands as the record for this date is the radar above, which caught the storm regardless.
Below the severe threshold
What 0.5" hail means for De Kalb roofs.
Radar signals under three-quarters of an inch stay below the National Weather Service severe threshold and generally indicate lower roof risk. Older or already-worn materials can still show effects, but radar alone cannot determine whether a specific roof was damaged.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$12K
Potential roof exposure — 1 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Claim window
August 2028
Claims from this storm can typically be filed until around August 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.
