Evidence / storm surfaces
How Iroquois saw the hail — from two instruments
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 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.
Only the NEXRAD radar-signature surface resolved for Jun 30, 2026 — the estimated-size swath had no hail signal to model for this storm, so there is one map to show, not two.
The storm in context
Where Jun 30, 2026 sits in Iroquois's hail record.
This was Iroquois's 4th recorded hail day, arriving 21 days after the Jun 9, 2026 storm. By severity it ranks 10th of the 10 storms we have logged here. Radar put the day's largest stone over Iroquois at 0" — radar-estimated size aloft.
The Jun 30, 2026 convective day was bigger than Iroquois: the same system put hail over 720 other tracked cities, 60 of them in South Dakota. Nearest: Cavour (14 miles southwest, up to 0"); Carthage (17 miles south, up to 0"); Oldham (28 miles southeast, up to 0").
These maps are stills. In the app this date is one of 10 Iroquois 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.
Ground reports
What people on the ground reported
These are storm reports filed with the National Weather Service and released through the NOAA Storm Prediction Center — public-domain observations from spotters, the public, and NWS surveys. We quote each one exactly as filed.
Nobody on the ground filed a report over Iroquois for this date, which says more about who was watching than about the storm: spotter reports only exist where there is an observer. The radar surfaces above carry the evidence for this one.
Below the severe threshold
What 0" hail means for Iroquois roofs.
Radar signals under three-quarters of an inch stay below the National Weather Service severe threshold and generally indicate lower roof risk. Older or already-worn materials can still show effects, but radar alone cannot determine whether a specific roof was damaged.
