How Peterson saw the hail — from two instruments
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
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.

Only the radar-estimated size surface resolved for Apr 14, 2026 — this storm produced no NEXRAD point detections over Peterson, so there is one map to show, not two.
Where Apr 14, 2026 sits in Peterson's hail record
This was Peterson's 2nd recorded hail day, arriving 15 days after the Mar 30, 2026 storm. By severity it ranks 3rd of the 5 storms we have logged here. Radar put the day's largest stone over Peterson at 0.5" — radar-estimated size aloft.
The Apr 14, 2026 convective day was bigger than Peterson: the same system put hail over 476 other tracked cities, 4 of them in Minnesota. Nearest: Lanesboro (7 miles south, up to 0.75"); Houston (15 miles east, up to 0.5"); Preston (17 miles southwest, up to 0.75").
These maps are stills from Peterson's Apr 14, 2026 storm. In the Overview app the same surfaces are live — radar updating in real time, radar-estimated hail size as it forms, and NWS spotter reports pinned where they're filed — with a radar replay you can scrub back over any past day.
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.

What 0.5" hail means for Peterson roofs
Hail under three-quarters of an inch stays below the National Weather Service severe threshold and rarely breaks shingles outright. But repeated small-hail events accelerate granule loss and shorten roof life — on older roofs, it's still worth a conversation.
What this storm is worth to a roofer
$1.5M
Potential roof exposure — 129 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

Other storms in Peterson
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 surfaces are detections and estimates,
not confirmed damage. Last updated Aug 3, 2026.
