Hail in Saint Francis · Aug 27, 2026
Hit 18 days ago
The estimated-size surface reached 2" aloft; NEXRAD logged no point detections over Saint Francis that day. 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.

How Saint Francis saw the hail — from two instruments
Aug 27, 2026 · Saint Francis, SD
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"
Only the radar-estimated size surface resolved for Aug 27, 2026 — this storm produced no NEXRAD point detections over Saint Francis, so there is one map to show, not two.
The storm in context
Where Aug 27, 2026 sits in Saint Francis's hail record.
This was Saint Francis's 14th recorded hail day, arriving 6 days after the Aug 21, 2026 storm. By severity it ranks 3rd of the 14 storms we have logged here. Radar put the day's largest stone over Saint Francis at 2" — radar-estimated size aloft.
The Aug 27, 2026 convective day was bigger than Saint Francis: the same system put hail over 365 other tracked cities, 13 of them in South Dakota. Nearest: Tuthill (10 miles southwest, up to 1.25"); Kilgore (13 miles southeast, up to 2.25"); Parmelee (14 miles north, up to 1.5").
These maps are stills. In the app this date is one of 14 Saint Francis 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" hail means for Saint Francis 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 28, 2026.
