Evidence / storm surfaces
How Alden saw the hail — from two instruments
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.
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.
Only the radar-estimated size surface resolved for Apr 15, 2026 — this storm produced no NEXRAD point detections over Alden, so there is one map to show, not two.
The storm in context
Where Apr 15, 2026 sits in Alden's hail record.
This was Alden's 2nd recorded hail day, arriving 12 days after the Apr 3, 2026 storm. By severity it ranks 7th of the 12 storms we have logged here. Radar put the day's largest stone over Alden at 0.5" — radar-estimated size aloft.
The Apr 15, 2026 convective day was bigger than Alden: the same system put hail over 425 other tracked cities, 127 of them in Iowa. Nearest: Iowa Falls (5 miles east, up to 0.5"); Ackley (10 miles east, up to 0.5"); Hampton (17 miles northeast, up to 0.5").
These maps are stills. In the app this date is one of 12 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
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.
Below the severe threshold
What 0.5" hail means for Alden 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.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$5M
Potential roof exposure — 416 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 2 jobs
- Illustrative work
- ~$30K
Close just 0.5% of the 416 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
April 2028
Claims from this storm can typically be filed until around April 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 $87 on top of the $150 plan.
