The estimated-size surface reached 1.5" aloft; NEXRAD logged no point detections over La Crosse that day. Open it on the live map to see the swath over the streets.
A tornado was also reported to the National Weather Service during this storm. The ground reports below show where it was filed.

Severity
Overview's storm severity score weighs hailstone size, homes in the footprint, and ground-truth reports.
Largest radar-indicated size — a signal of damage potential, not confirmation.

Evidence / storm surfaces
We map this storm two ways: the NEXRAD radar signatures the storm produced overhead, and the radar-estimated size of the hail in the air. The two surfaces don’t have to match — where they diverge is where estimated size aloft ran ahead of, or behind, what the signatures caught.
Estimated size field Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.
Only the radar-estimated size surface resolved for Mar 10, 2026 — this storm produced no NEXRAD point detections over La Crosse, so there is one map to show, not two.
The storm in context
This was La Crosse's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 2nd 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 Mar 10, 2026 convective day was bigger than La Crosse: the same system put hail over 470 other tracked cities, 21 of them in Indiana. Nearest: Wheatfield (12 miles southwest, up to 1.5"); Knox (13 miles east, up to 1"); Union Mills (14 miles north, up to 0.75").
These maps are stills. In the app this date is one of 6 La Crosse 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
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.
“Based on radar... an NWS Survey and reports from numerous spotter and emergency management officials... one final tornado has been confirmed with a cyclic supercell tha (IWX)”
— NOAA / SPC storm report
“Observed tornado by spotter video (delayed report). (IWX)”
— NOAA / SPC storm report
“Healthy 1ft diameter trees uprooted. Some snapped at the top. (IWX)”
— NOAA / SPC storm report
“Video obtained from storm chasers claiming to be on the south-southeast side of the parent mesocyclone clearly show two distinct tornadoes occurring at the same time. O (IWX)”

Storm forensics
Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.
Hail was reported over 20 minutes, from to .
Reports came from Lomax, English Lake, and Toto — beyond La Crosse itself.
High damage potential
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
Potential roof exposure
$12M
Potential roof exposure — 964 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Close just 0.5% of the 964 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
March 2028
Claims from this storm can typically be filed until around March 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 $202 on top of the $150 plan.
