Evidence / storm surfaces
How Lennox 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.
Radar signature field Where NEXRAD flagged hail as the storm passed — point signatures from the radar, which indicate hail overhead rather than confirm what landed.
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.
The storm in context
Where Aug 20, 2026 sits in Lennox's hail record.
This was Lennox's 6th recorded hail day, arriving 10 days after the Aug 10, 2026 storm. By severity it ranks 5th of the 8 storms we have logged here. Radar put the day's largest stone over Lennox at 1" — radar-estimated size aloft.
The Aug 20, 2026 convective day was bigger than Lennox: the same system put hail over 640 other tracked cities, 17 of them in South Dakota. Nearest: Chancellor (10 miles northwest, up to 2"); Centerville (15 miles south, up to 1"); Hartford (16 miles northwest, up to 2").
These maps are stills. In the app this date is one of 8 Lennox 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.
No ground reports were filed with the National Weather Service for this storm over Lennox. 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.
Damage-capable hail signal
What 1" hail means for Lennox roofs.
Quarter-size and larger hail can bruise asphalt mats, remove granules, and dent exposed soft metal. The mapped footprint identifies an inspection priority area — it does not identify which individual roofs, if any, sustained damage.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$28M
Potential roof exposure — 2,320 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 12 jobs
- Illustrative work
- ~$180K
Close just 0.5% of the 2,320 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 $487 on top of the $150 plan.
