Evidence / storm surfaces
How Indianapolis saw the hail — from two instruments
Jul 27, 2026 · Indianapolis, 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.
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.
Max size
1"
Only the radar-estimated size surface resolved for Jul 27, 2026 — this storm produced no NEXRAD point detections over Indianapolis, so there is one map to show, not two.
The storm in context
Where Jul 27, 2026 sits in Indianapolis's hail record.
This was Indianapolis's 5th recorded hail day, arriving 23 days after the Jul 4, 2026 storm. By severity it ranks 2nd of the 7 storms we have logged here. Radar put the day's largest stone over Indianapolis at 1" — radar-estimated size aloft.
The Jul 27, 2026 convective day was bigger than Indianapolis: the same system put hail over 803 other tracked cities, 71 of them in Indiana. Nearest: Carmel (7 miles north, up to 1"); Westfield (9 miles northwest, up to 0.75"); Noblesville (17 miles northeast, up to 0.5").
These maps are stills. In the app this date is one of 7 Indianapolis 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.

Storm forensics
How the storm moved
Timing and place names from NOAA ground reports

Hail was reported over 42 minutes, from to .
Reports came from Indianapolis Intl Airp, Broad Ripple 2 Ne, and Indianapolis Int'L Airp — beyond Indianapolis itself.
Damage-capable hail signal
What 1" hail means for Indianapolis 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.

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 Aug 16, 2026.
