NEXRAD logged 0 hail signatures up to 1.75"; the estimated-size surface reached 0.75" aloft. Open it on the live map to see the swath over the streets.

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.
How many homes sit inside the storm's footprint.
Independent storm reports filed with the NWS.
Evidence / storm surfaces
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
This was Canby's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 1st of the 6 storms we have logged here. Radar put the day's largest stone over Canby at 1.75" — the largest NEXRAD radar signature.
The Jun 3, 2026 convective day was bigger than Canby: the same system put hail over 274 other tracked cities, 7 of them in Minnesota. Nearest: Gary (23 miles northwest, up to 1.75"); Lake Benton (28 miles south, up to 0.5"); Balaton (33 miles southeast, up to 0.5").
These maps are stills. In the app this date is one of 6 Canby 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.

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
$17M
Potential roof exposure — 1,450 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Close just 0.5% of the 1,450 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
June 2028
Claims from this storm can typically be filed until around June 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 $305 on top of the $150 plan.
