Evidence / storm surfaces
How Opp saw the hail — from two instruments
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 signature field The point detections NEXRAD recorded overhead. Each signature marks where the radar saw hail aloft — it is a detection, not a stone measured on the ground.
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.
The storm in context
Where Aug 17, 2026 sits in Opp's hail record.
This was Opp's 3rd recorded hail day, arriving 38 days after the Jul 10, 2026 storm. By severity it ranks 1st of the 4 storms we have logged here. Radar put the day's largest stone over Opp at 0.75" — radar-estimated size aloft.
The Aug 17, 2026 convective day was bigger than Opp: the same system put hail over 428 other tracked cities, 34 of them in Alabama. Nearest: Crestview (42 miles southwest, up to 0.75"); Fort Deposit (56 miles north, up to 0.5"); Holt (59 miles southwest, up to 0.75").

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 Opp, 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 Opp 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
$4.4M
Potential roof exposure — 364 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
