Hail in Kimball Jul 2, 2026
Hit 32 days agoBoth radar surfaces caught this storm: NEXRAD logged 52 hail signatures up to 2.75", and the radar-estimated size reached 2.25" aloft. At 2.75" — baseball — this is severe, roof-replacing hail: close to every roof inside the footprint becomes a claim candidate.
A tornado was also reported to the National Weather Service during this storm — see the ground reports below.

How Kimball saw the hail — from two instruments
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
Where NEXRAD flagged hail as the storm passed — point signatures from the radar, which indicate hail overhead rather than confirm what landed.

Where Jul 2, 2026 sits in Kimball's hail record
This was Kimball's 5th recorded hail day, arriving 2 days after the Jun 30, 2026 storm. By severity it ranks 1st of the 6 storms we have logged here. Radar put the day's largest stone over Kimball at 2.75" — the largest NEXRAD radar signature.
The Jul 2, 2026 convective day was bigger than Kimball: the same system put hail over 1,147 other tracked cities, 153 of them in South Dakota. Nearest: Pukwana (5 miles west, up to 2.75"); Gann Valley (15 miles north, up to 2.75"); Chamberlain (16 miles southwest, up to 2.5").
These maps are stills from Kimball's Jul 2, 2026 storm. In the Overview app the same surfaces are live — radar updating in real time, radar-estimated hail size as it forms, and NWS spotter reports pinned where they're filed — with a radar replay you can scrub back over any past day.
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.

Reports came from Gann Valley, Pukwana, and Wessington Sprin — beyond Kimball itself.
What 2.75" hail means for Kimball roofs
Two-inch-plus hail punctures shingles, breaks skylights and windows, and dents anything soft. In the core of a footprint like this, close to every roof is a candidate for an insurance claim. Speed decides who writes those jobs.
What this storm is worth to a roofer
$3.9M
Potential roof exposure — 324 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 surfaces are detections and estimates,
not confirmed damage. Last updated Aug 3, 2026.
