Evidence / storm surfaces
How Blue Mountain 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 17, 2026 — this storm produced no NEXRAD point detections over Blue Mountain, so there is one map to show, not two.
The storm in context
Where Aug 17, 2026 sits in Blue Mountain's hail record.
This was Blue Mountain's 6th recorded hail day, arriving 38 days after the Jul 10, 2026 storm. By severity it ranks 5th of the 6 storms we have logged here. Radar put the day's largest stone over Blue Mountain at 0.5" — radar-estimated size aloft.
The Aug 17, 2026 convective day was bigger than Blue Mountain: the same system put hail over 428 other tracked cities, 29 of them in Mississippi. Nearest: Ripley (13 miles northeast, up to 0.75"); Blue Springs (15 miles south, up to 0.5"); Ashland (21 miles north, 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 Blue Mountain, 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.
Below the severe threshold
What 0.5" hail means for Blue Mountain 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
$2M
Potential roof exposure — 170 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 1 job
- Illustrative work
- ~$15K
Close just 0.5% of the 170 homes in this footprint at the average $15,000 roof job. Illustrative math, not a projection — your results depend on your outreach and how the market responds.
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 $36 on top of the $150 plan.
