Evidence / storm surfaces
How Lagrange 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.
Estimated size field Radar-estimated maximum hail size across the swath, modeled from radar aloft. It reflects the biggest stone the storm could support, which may differ from what actually fell.
The storm in context
Where Aug 25, 2026 sits in Lagrange's hail record.
This was Lagrange's 10th recorded hail day, arriving 9 days after the Aug 16, 2026 storm. By severity it ranks 3rd of the 11 storms we have logged here. Radar put the day's largest stone over Lagrange at 1.5" — radar-estimated size aloft.
The Aug 25, 2026 convective day was bigger than Lagrange: the same system put hail over 205 other tracked cities, 3 of them in Wyoming. Nearest: Albin (15 miles southeast, up to 1"); Harrisburg (37 miles east, up to 1.25"); Bushnell (40 miles southeast, up to 0.5").
These maps are stills. In the app this date is one of 11 Lagrange 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.

Storm forensics
How the storm moved
Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.
The storm tracked southeast at roughly 20 mph, based on the timing of ground reports.
Hail was reported over 40 minutes, from to .
Reports came from La Grange and Hawk Springs — beyond Lagrange itself.
High damage potential
What 1.5" hail means for Lagrange 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.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$1.2M
Potential roof exposure — 103 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 103 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 $22 on top of the $150 plan.
