Evidence / storm surfaces
How Turtle Lake saw the hail — from two instruments
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.
Radar signature field NEXRAD radar signatures — the point detections the storm produced overhead. A signature is where the radar saw hail, not a confirmed stone on the ground.
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.
The storm in context
Where Apr 11, 2026 sits in Turtle Lake's hail record.
This was Turtle Lake's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 3rd of the 7 storms we have logged here. Radar put the day's largest stone over Turtle Lake at 1" — the largest NEXRAD radar signature.
The Apr 11, 2026 convective day was bigger than Turtle Lake: the same system put hail over 134 other tracked cities, 9 of them in Wisconsin. Nearest: Amery (8 miles southwest, up to 1"); Clayton (10 miles southeast, up to 0"); Osceola (21 miles west, up to 0").

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 Turtle Lake, 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.
Damage-capable hail signal
What 1" hail means for Turtle Lake 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
$900K
Potential roof exposure — 75 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Claim window
April 2028
Claims from this storm can typically be filed until around April 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 $16 on top of the $150 plan.
