Evidence / storm surfaces

How Winner saw the hail — from two instruments

Jul 19, 2026 · Winner, SD

Each storm gets two readings: the radar signatures NEXRAD recorded as the cells passed overhead, and a modeled estimate of hail size in the air. They are independent surfaces, so a mismatch between them is expected — and worth reading.

Radar-estimated hail-size map of the storm over Winner, SD on Jul 19, 2026 Estimated size field

Radar-estimated hail size over the swath. The model reports the biggest stone the storm could sustain in the air; what actually fell may have been smaller.

Max size 0.75"

Only the radar-estimated size surface resolved for Jul 19, 2026 — this storm produced no NEXRAD point detections over Winner, so there is one map to show, not two.

The storm in context

Where Jul 19, 2026 sits in Winner's hail record.

This was Winner's 8th recorded hail day, arriving 13 days after the Jul 6, 2026 storm. By severity it ranks 11th of the 15 storms we have logged here. Radar put the day's largest stone over Winner at 0.75" — radar-estimated size aloft.

The Jul 19, 2026 convective day was bigger than Winner: the same system put hail over 351 other tracked cities, 16 of them in South Dakota. Nearest: Dallas (5 miles east, up to 0.75"); Hamill (19 miles northwest, up to 0.75"); Kennebec (46 miles north, up to 0.5").

These maps are stills. In the app this date is one of 15 Winner 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

No reports filed with the NWS

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 Winner 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.

Near the severe threshold

What 0.75" hail means for Winner roofs.

A signal this size sits near the National Weather Service severe threshold. Aging shingles and soft metals such as vents, flashing, and gutters may be more vulnerable; roof age, wind, and material condition all matter, and only an inspection can confirm 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 tells you where to look. Only an inspection confirms damage at an address. Last updated Aug 20, 2026.
