Hail in Tracy · Jun 11, 2026
The estimated-size surface reached 2.25" aloft; NEXRAD logged no point detections over Tracy that day. At 2.25" — tennis ball — this is a severe hail signal associated with roof damage. Open it on the live map to see the swath over the streets.

How Tracy saw the hail — from two instruments
Jun 11, 2026 · Tracy, IA
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
2.25"
Only the radar-estimated size surface resolved for Jun 11, 2026 — this storm produced no NEXRAD point detections over Tracy, so there is one map to show, not two.
The storm in context
Where Jun 11, 2026 sits in Tracy's hail record.
This was Tracy's 2nd recorded hail day, arriving 55 days after the Apr 17, 2026 storm. By severity it ranks 1st of the 3 storms we have logged here. Radar put the day's largest stone over Tracy at 2.25" — radar-estimated size aloft.
The Jun 11, 2026 convective day was bigger than Tracy: the same system put hail over 648 other tracked cities, 147 of them in Iowa. Nearest: Knoxville (5 miles west, up to 2.75"); Bussey (7 miles south, up to 3"); Hamilton (9 miles southwest, up to 2.75").
These maps are stills. In the app this date is one of 3 Tracy 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.

Severe hail signal
What 2.25" hail means for Tracy roofs.
Two-inch-plus hail is capable of puncturing shingles, breaking skylights or windows, and heavily denting soft materials. The strongest radar bands warrant prompt inspection, but neither the signal nor the footprint confirms damage at a specific address.

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 3, 2026.
