Evidence / storm surfaces
How Warren saw the hail — from two instruments
Sep 3, 2026 · Warren, MN
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 Sep 3, 2026 sits in Warren's hail record.
This was Warren's 9th recorded hail day, arriving 10 days after the Aug 24, 2026 storm. By severity it ranks 4th of the 10 storms we have logged here. Radar put the day's largest stone over Warren at 0.75" — radar-estimated size aloft.

Near the severe threshold
What 0.75" hail means for Warren roofs.
A signal this size sits near the National Weather Service severe threshold. Aging shingles and soft metals such as vents, flashing, and gutters may be more vulnerable; roof age, wind, and material condition all matter, and only an inspection can confirm damage.

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 Sep 7, 2026.
