Evidence / storm surfaces
How Argyle saw the hail — from two instruments
Aug 17, 2026 · Argyle, MN
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-estimated hail size Surface resolved
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.
Max size
0.5"
Only the radar-estimated size surface resolved for Aug 17, 2026 — this storm produced no NEXRAD point detections over Argyle, so there is one map to show, not two.
The storm in context
Where Aug 17, 2026 sits in Argyle's hail record.
This was Argyle's 8th recorded hail day, arriving 15 days after the Aug 2, 2026 storm. By severity it ranks 5th of the 10 storms we have logged here. Radar put the day's largest stone over Argyle at 0.5" — radar-estimated size aloft.
The Aug 17, 2026 convective day was bigger than Argyle: the same system put hail over 428 other tracked cities, 51 of them in Minnesota. Nearest: Warren (7 miles south, up to 0.5"); Grafton (31 miles west, up to 0.5"); Gary (67 miles south, up to 0.5").
These maps are stills. In the app this date is one of 10 Argyle 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
What people on the ground reported
1 report filed with the NWS
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.

Reports came from Alvarado — beyond Argyle itself.
Below the severe threshold
What 0.5" hail means for Argyle roofs.
Radar signals under three-quarters of an inch stay below the National Weather Service severe threshold and generally indicate lower roof risk. Older or already-worn materials can still show effects, but radar alone cannot determine whether a specific roof was damaged.

Potential roof exposure — 16 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Claim window
August 2028
Claims from this storm can typically be filed until around August 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.

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.
