Evidence / storm surfaces
How La Crosse 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 11, 2026 — this storm produced no NEXRAD point detections over La Crosse, so there is one map to show, not two.
The storm in context
Where Aug 11, 2026 sits in La Crosse's hail record.
This was La Crosse's 6th recorded hail day, arriving 1 day after the Aug 10, 2026 storm. By severity it ranks 1st of the 6 storms we have logged here. Radar put the day's largest stone over La Crosse at 1.5" — radar-estimated size aloft.
The Aug 11, 2026 convective day was bigger than La Crosse: the same system put hail over 1,041 other tracked cities, 170 of them in Indiana. Nearest: North Judson (7 miles south, up to 1.5"); San Pierre (7 miles south, up to 1.5"); Wanatah (7 miles north, up to 1").

Storm forensics
How the storm moved
Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.
Hail was reported over 40 minutes, from to .
Reports came from English Lake, Toto, and North Judson — beyond La Crosse itself.
High damage potential
What 1.5" hail means for La Crosse 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.
