Evidence / storm surfaces
How Alden 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.
Only the NEXRAD radar-signature surface resolved for Apr 3, 2026 — the estimated-size swath had no hail signal to model for this storm, so there is one map to show, not two.
The storm in context
Where Apr 3, 2026 sits in Alden's hail record.
This was Alden's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 10th of the 12 storms we have logged here. Radar put the day's largest stone over Alden at 0.5" — the largest NEXRAD radar signature.
The Apr 3, 2026 convective day was bigger than Alden: the same system put hail over 367 other tracked cities, 36 of them in Iowa. Nearest: Story City (32 miles southwest, up to 0"); Holland (34 miles southeast, up to 0.75"); Colo (38 miles south, 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.
Nobody on the ground filed a report over Alden 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.
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
$516K
Potential roof exposure — 43 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
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.
