How Valparaiso 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.
NEXRAD radar signatures
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 13, 2026 — the estimated-size swath had no hail signal to model for this storm, so there is one map to show, not two.
Where Apr 13, 2026 sits in Valparaiso's hail record
This was Valparaiso's 5th recorded hail day, arriving 13 days after the Mar 31, 2026 storm. By severity it ranks 7th of the 9 storms we have logged here. Radar put the day's largest stone over Valparaiso at 0.5" — the largest NEXRAD radar signature.
The Apr 13, 2026 convective day was bigger than Valparaiso: the same system put hail over 467 other tracked cities, 24 of them in Indiana. Nearest: Wanatah (9 miles southeast, up to 0.5"); Hanna (12 miles southeast, up to 0.75"); Michigan City (15 miles north, up to 0.75").
These maps are stills from Valparaiso's Apr 13, 2026 storm. In the Overview app the same surfaces are live — radar updating in real time, radar-estimated hail size as it forms, and NWS spotter reports pinned where they're filed — with a radar replay you can scrub back over any past day.
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.
Wind reports
1 reportWhat 0.5" hail means for Valparaiso roofs
Hail under three-quarters of an inch stays below the National Weather Service severe threshold and rarely breaks shingles outright. But repeated small-hail events accelerate granule loss and shorten roof life — on older roofs, it's still worth a conversation.
What this storm is worth to a roofer
$660K
Potential roof exposure — 55 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage. 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.

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 surfaces are detections and estimates,
not confirmed damage. Last updated Aug 3, 2026.
