Evidence / storm surfaces

How Frazee saw the hail — from two instruments

Aug 17, 2026 · Frazee, MN

Each storm gets two readings: the radar signatures NEXRAD recorded as the cells passed overhead, and a modeled estimate of hail size in the air. They are independent surfaces, so a mismatch between them is expected — and worth reading.

Radar-estimated hail size Surface resolved
Radar-estimated hail-size map of the storm over Frazee, MN on Aug 17, 2026 Estimated size field

Radar-estimated hail size over the swath. The model reports the biggest stone the storm could sustain in the air; what actually fell may have been smaller.

Max size 1.5"

Only the radar-estimated size surface resolved for Aug 17, 2026 — this storm produced no NEXRAD point detections over Frazee, so there is one map to show, not two.

The storm in context

Where Aug 17, 2026 sits in Frazee's hail record.

This was Frazee's 5th recorded hail day, arriving 42 days after the Jul 6, 2026 storm. By severity it ranks 2nd of the 5 storms we have logged here. Radar put the day's largest stone over Frazee at 1.5" — radar-estimated size aloft.

The Aug 17, 2026 convective day was bigger than Frazee: the same system put hail over 428 other tracked cities, 51 of them in Minnesota. Nearest: Perham (8 miles southeast, up to 1.5"); Richville (14 miles south, up to 0.75"); Audubon (16 miles northwest, up to 0.5").

These maps are stills. In the app this date is one of 5 Frazee 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

No reports 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.

For this storm over Frazee, the NWS report log is empty — a common outcome, since ground reports only happen when someone witnesses the hail and takes the time to call it in. The detection record for the date lives in the radar maps above.

High damage potential

What 1.5" hail means for Frazee roofs.

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.

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 18, 2026.
