Hail in Stockholm · Apr 13, 2026
NEXRAD logged 21 hail signatures up to 2.5"; the estimated-size surface reached 2" aloft. At 2.5" — baseball — this is a severe hail signal associated with roof damage. Open it on the live map to see the swath over the streets.

Evidence / storm surfaces
How Stockholm saw the hail — from two instruments
Apr 13, 2026 · Stockholm, WI
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-estimated hail size Surface resolved
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 Apr 13, 2026 sits in Stockholm's hail record.
This was Stockholm's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 1st of the 1 storms we have logged here. Radar put the day's largest stone over Stockholm at 2.5" — the largest NEXRAD radar signature.
The Apr 13, 2026 convective day was bigger than Stockholm: the same system put hail over 467 other tracked cities, 108 of them in Wisconsin. Nearest: Lake City (7 miles south, up to 4"); Pepin (7 miles east, up to 2.5"); Plum City (8 miles northeast, up to 2.25").
These maps are stills. In the app this date is one of 1 Stockholm storm date 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.

Severe hail signal
What 2.5" hail means for Stockholm roofs.
Two-inch-plus hail is capable of puncturing shingles, breaking skylights or windows, and heavily denting soft materials. The strongest radar bands warrant prompt inspection, but neither the signal nor the footprint confirms damage at a specific address.

2,906 homes × $12,000 avg. claim
Potential roof exposure

A storm day here is a convective day — it runs from noon to noon
UTC, so late-night hail is grouped with the afternoon storm that
spawned it rather than split across two calendar dates. Ground
reports are public-domain observations from the NOAA Storm
Prediction Center. Radar tells you where to look. Only an inspection confirms damage at an address. Last updated Aug 2, 2026.
