Evidence / storm surfaces
How Brookings 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 Aug 28, 2026 — this storm produced no NEXRAD point detections over Brookings, so there is one map to show, not two.
The storm in context
Where Aug 28, 2026 sits in Brookings's hail record.
This was Brookings's 4th recorded hail day, arriving 22 days after the Aug 6, 2026 storm. By severity it ranks 4th of the 5 storms we have logged here. Radar put the day's largest stone over Brookings at 0.5" — radar-estimated size aloft.
The Aug 28, 2026 convective day was bigger than Brookings: the same system put hail over 185 other tracked cities, 28 of them in South Dakota. Nearest: Estelline (21 miles north, up to 0.5"); Wentworth (22 miles south, up to 0.75"); Ramona (24 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.
No ground reports were filed with the National Weather Service for this storm over Brookings. That is common: a report depends on someone being there to see it and take the time to call it in. The radar surfaces above are the record here — the storm was detected from above even though no one on the ground logged it.
Below the severe threshold
What 0.5" hail means for Brookings 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
$60K
Potential roof exposure — 5 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.
Names and phones for every home in the footprint: at most $1 on top of the $150 plan.
