Evidence / storm surfaces
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.
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 Jul 20, 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 Jul 20, 2026 sits in Valparaiso's hail record.
This was Valparaiso's 9th recorded hail day, arriving 17 days after the Jul 3, 2026 storm. By severity it ranks 11th of the 12 storms we have logged here. Radar put the day's largest stone over Valparaiso at 1" — the largest NEXRAD radar signature.
The Jul 20, 2026 convective day was bigger than Valparaiso: the same system put hail over 553 other tracked cities, 15 of them in Indiana. Nearest: Gary (12 miles northwest, up to 1"); Westville (12 miles northeast, up to 1"); Cedar Lake (22 miles west, up to 1").
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
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 Valparaiso, 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.
Damage-capable hail signal
What 1" hail means for Valparaiso roofs.
Quarter-size and larger hail can bruise asphalt mats, remove granules, and dent exposed soft metal. The mapped footprint identifies an inspection priority area — it does not identify which individual roofs, if any, sustained damage.
