Evidence / storm surfaces
How Philip saw the hail — from two instruments
Aug 11, 2026 · Philip, 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.
NEXRAD radar signatures Surface resolved
Radar signature field Where NEXRAD flagged hail as the storm passed — point signatures from the radar, which indicate hail overhead rather than confirm what landed.

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.

The storm in context
Where Aug 11, 2026 sits in Philip's hail record.
This was Philip's 13th recorded hail day, arriving 1 day after the Aug 10, 2026 storm. By severity it ranks 4th of the 14 storms we have logged here. Radar put the day's largest stone over Philip at 1.5" — radar-estimated size aloft.
The Aug 11, 2026 convective day was bigger than Philip: the same system put hail over 1,041 other tracked cities, 44 of them in South Dakota. Nearest: Quinn (10 miles west, up to 2.5"); Wall (22 miles southwest, up to 2.75"); Howes (25 miles north, up to 0.5").
These maps are stills. In the app this date is one of 14 Philip 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.

High damage potential
What 1.5" hail means for Philip roofs.
Hail around an inch and a half is capable of cracking shingles, stripping granules, and denting gutters, vents, and siding. Risk is usually greatest near the strongest radar signal, but property-level damage still requires an on-site inspection.

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 14, 2026.
