Evidence / storm surfaces
How Pierpont 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 27, 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 27, 2026 sits in Pierpont's hail record.
This was Pierpont's 2nd recorded hail day, arriving 66 days after the Apr 22, 2026 storm. By severity it ranks 3rd of the 4 storms we have logged here. Radar put the day's largest stone over Pierpont at 1" — the largest NEXRAD radar signature.
The Jun 27, 2026 convective day was bigger than Pierpont: the same system put hail over 587 other tracked cities, 131 of them in South Dakota. Nearest: Houghton (28 miles northwest, up to 1"); Columbia (31 miles west, up to 1"); Florence (32 miles southeast, up to 1").
These maps are stills. In the app this date is one of 4 Pierpont 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 Pierpont 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.
Damage-capable hail signal
What 1" hail means for Pierpont roofs.
Quarter-size and larger hail can bruise asphalt mats, remove granules, and dent exposed soft metal. The mapped footprint identifies an inspection priority area — it does not identify which individual roofs, if any, sustained damage.
