Evidence / storm surfaces
How Valparaiso saw the hail — from two instruments
Mar 10, 2026 · Valparaiso, 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.
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.
Max size
1.25"
Only the radar-estimated size surface resolved for Mar 10, 2026 — this storm produced no NEXRAD point detections over Valparaiso, so there is one map to show, not two.
The storm in context
Where Mar 10, 2026 sits in Valparaiso's hail record.
This was Valparaiso's 2nd recorded hail day, arriving 4 days after the Mar 6, 2026 storm. By severity it ranks 1st of the 12 storms we have logged here. Radar put the day's largest stone over Valparaiso at 1.25" — radar-estimated size aloft.
The Mar 10, 2026 convective day was bigger than Valparaiso: the same system put hail over 470 other tracked cities, 21 of them in Indiana. Nearest: Hobart (5 miles west, up to 0.75"); Chesterton (9 miles northeast, up to 1.25"); Portage (9 miles northwest, 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.

Damage-capable hail signal
What 1.25" 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.

Roofing exposure
What this storm is worth to a roofer.
27,638 homes × $12,000 avg. claim
Potential roof exposure
$332M
Potential roof exposure — 27,638 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

- 138 jobs
- Illustrative work
- ~$2.1M
Close just 0.5% of the 27,638 homes in this footprint at the average $15,000 roof job. Illustrative math, not a projection — your results depend on your outreach and how the market responds.

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.
