Evidence / storm surfaces
How Atlanta 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.
Only the NEXRAD radar-signature surface resolved for Mar 15, 2026 — the estimated-size swath had no hail signal to model for this storm, so there is one map to show, not two.
The storm in context
Where Mar 15, 2026 sits in Atlanta's hail record.
This was Atlanta's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 9th of the 11 storms we have logged here. Radar put the day's largest stone over Atlanta at 1.75" — the largest NEXRAD radar signature.
The Mar 15, 2026 convective day was bigger than Atlanta: the same system put hail over 695 other tracked cities, 22 of them in Georgia. Nearest: Fairburn (21 miles southwest, up to 1.75"); Cartersville (33 miles northwest, up to 0"); Jasper (45 miles north, up to 0").
These maps are stills. In the app this date is one of 11 Atlanta 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.
For this storm over Atlanta, 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 1.75" hail means for Atlanta 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.
