Hail in Letcher · Jul 2, 2026
NEXRAD logged 15 hail signatures up to 2"; the estimated-size surface reached 1.5" aloft. At 2" — 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.

Evidence / storm surfaces
How Letcher saw the hail — from two instruments
Jul 2, 2026 · Letcher, SD
Two instruments, one storm: NEXRAD logs the point signatures it detected overhead, while the estimated-size surface models how large the hail aloft could have grown. Agreement between them is not guaranteed — the gaps are where the model ran ahead of, or behind, the detections.

The storm in context
Where Jul 2, 2026 sits in Letcher's hail record.
This was Letcher's 3rd recorded hail day, arriving 2 days after the Jun 30, 2026 storm. By severity it ranks 2nd of the 5 storms we have logged here. Radar put the day's largest stone over Letcher at 2" — the largest NEXRAD radar signature.
The Jul 2, 2026 convective day was bigger than Letcher: the same system put hail over 1,147 other tracked cities, 153 of them in South Dakota. Nearest: Plankinton (9 miles southwest, up to 1.75"); Woonsocket (10 miles north, up to 1.75"); Mitchell (19 miles southeast, up to 1.75").

Severe hail signal
What 2" hail means for Letcher 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 5, 2026.
