Evidence / storm surfaces
How Terre Haute saw the hail — from two instruments
Apr 27, 2026 · Terre Haute, IN
The maps here read the same storm from two angles — point detections from NEXRAD, and modeled hail size aloft. Where the two disagree is informative: it marks where estimated size outran the signatures, or trailed them.
NEXRAD radar signatures Surface resolved
Radar signature field Where NEXRAD flagged hail as the storm passed — point signatures from the radar, which indicate hail overhead rather than confirm what landed.

Radar-estimated hail size Surface resolved
Estimated size field The modeled maximum hail size across the swath, derived from radar aloft — the largest stone the storm could have supported, which is not necessarily what reached the ground.

The storm in context
Where Apr 27, 2026 sits in Terre Haute's hail record.
This was Terre Haute's 4th recorded hail day, arriving 27 days after the Mar 31, 2026 storm. By severity it ranks 3rd of the 13 storms we have logged here. Radar put the day's largest stone over Terre Haute at 1.75" — the largest NEXRAD radar signature.
The Apr 27, 2026 convective day was bigger than Terre Haute: the same system put hail over 1,188 other tracked cities, 125 of them in Indiana. Nearest: Marshall (11 miles west, up to 1.75"); West Union (11 miles west, up to 1.75"); Fairbanks (12 miles southwest, up to 1.75").
These maps are stills. In the app this date is one of 13 Terre Haute 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.

High damage potential
What 1.75" hail means for Terre Haute roofs.
Hail around an inch and a half is capable of cracking shingles, stripping granules, and denting gutters, vents, and siding. Risk is usually greatest near the strongest radar signal, but property-level damage still requires an on-site inspection.

What this storm is worth to a roofer.
438 homes × $12,000 avg. claim
Potential roof exposure
$5.3M
Potential roof exposure — 438 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed 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 12, 2026.
