How Alden saw the hail — from two instruments

Jul 2, 2026 · Alden, 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.

NEXRAD radar signatures — the point detections the storm produced overhead. A signature is where the radar saw hail, not a confirmed stone on the ground.

The storm in context

Where Jul 2, 2026 sits in Alden's hail record.

This was Alden's 9th recorded hail day, arriving 1 day after the Jul 1, 2026 storm. By severity it ranks 6th of the 14 storms we have logged here. Radar put the day's largest stone over Alden at 1.25" — the largest NEXRAD radar signature.

The Jul 2, 2026 convective day was bigger than Alden: the same system put hail over 1,147 other tracked cities, 63 of them in Minnesota. Nearest: Wells (8 miles northwest, up to 1.5"); Walters (9 miles southwest, up to 1.5"); Hartland (9 miles northeast, up to 0.5").

These maps are stills. In the app this date is one of 14 Alden 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 Alden, 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.

Damage-capable hail signal

What 1.25" hail means for Alden roofs.

Quarter-size and larger hail can bruise asphalt mats, remove granules, and dent exposed soft metal. The mapped footprint identifies an inspection priority area — it does not identify which individual roofs, if any, sustained damage.

Roofing exposure

What this storm is worth to a roofer.

350 homes × $12,000 avg. claim

Potential roof exposure

$4.2M

Potential roof exposure — 350 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed 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 2, 2026.
