Evidence / storm surfaces
How Spirit Lake saw the hail — from two instruments
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 signature field 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.
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.
The storm in context
Where Jul 1, 2026 sits in Spirit Lake's hail record.
This was Spirit Lake's 10th recorded hail day, arriving 1 day after the Jun 30, 2026 storm. By severity it ranks 5th of the 18 storms we have logged here. Radar put the day's largest stone over Spirit Lake at 1.75" — the largest NEXRAD radar signature.
The Jul 1, 2026 convective day was bigger than Spirit Lake: the same system put hail over 1,147 other tracked cities, 86 of them in Iowa. Nearest: Terril (13 miles southeast, up to 1.75"); Estherville (13 miles east, up to 1.5"); Dickens (17 miles south, up to 1").
These maps are stills. In the app this date is one of 18 Spirit Lake 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
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.
Nobody on the ground filed a report over Spirit Lake for this date, which says more about who was watching than about the storm: spotter reports only exist where there is an observer. The radar surfaces above carry the evidence for this one.
High damage potential
What 1.75" hail means for Spirit Lake 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.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$10M
Potential roof exposure — 858 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 4 jobs
- Illustrative work
- ~$60K
Close just 0.5% of the 858 homes in this footprint at the average $15,000 roof job. Illustrative math, not a projection — your results depend on your outreach and how the market responds.
Claim window
July 2028
Claims from this storm can typically be filed until around July 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.
Names and phones for every home in the footprint: at most $180 on top of the $150 plan.
