How Knoxville saw the hail — from two instruments
Jun 5, 2026 · Knoxville, IA
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.
NEXRAD radar signatures Surface resolved
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.

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.

The storm in context
Where Jun 5, 2026 sits in Knoxville's hail record.
This was Knoxville's 4th recorded hail day, arriving 18 days after the May 18, 2026 storm. By severity it ranks 2nd of the 11 storms we have logged here. Radar put the day's largest stone over Knoxville at 2.5" — the largest NEXRAD radar signature.
The Jun 5, 2026 convective day was bigger than Knoxville: the same system put hail over 440 other tracked cities, 66 of them in Iowa. Nearest: Hamilton (7 miles south, up to 1.75"); Bussey (9 miles southeast, up to 0.5"); Melcher Dallas (12 miles southwest, up to 2.5").
These maps are stills. In the app this date is one of 11 Knoxville 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.

The storm tracked southeast at roughly 5 mph, based on the timing of ground reports.
Hail was reported over 83 minutes, from to .
Reports came from Pleasantville — beyond Knoxville itself.
Severe hail signal
What 2.5" hail means for Knoxville 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 Sep 9, 2026.
