Evidence / storm surfaces
How Valparaiso saw the hail — from two instruments
Apr 13, 2026 · Valparaiso, IN
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 Surface resolved
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.

Radar-estimated hail size Surface resolved
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 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 9th of the 12 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 (12 miles southeast, up to 0.5"); Crown Point (15 miles southwest, up to 1"); Hanna (17 miles southeast, up to 0.75").
These maps are stills. In the app this date is one of 12 Valparaiso 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
1 report 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.
Wind reports
1 reportBelow the severe threshold
What 0.5" hail means for Valparaiso 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.

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 16, 2026.
