Evidence / storm surfaces

How Herrick saw the hail — from two instruments

Aug 3, 2026 · Herrick, 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.

The point detections NEXRAD recorded overhead. Each signature marks where the radar saw hail aloft — it is a detection, not a stone measured on the ground.

The storm in context

Where Aug 3, 2026 sits in Herrick's hail record.

This was Herrick's 5th recorded hail day, arriving 4 days after the Jul 30, 2026 storm. By severity it ranks 5th of the 8 storms we have logged here. Radar put the day's largest stone over Herrick at 0.75" — radar-estimated size aloft.

The Aug 3, 2026 convective day was bigger than Herrick: the same system put hail over 172 other tracked cities, 23 of them in South Dakota. Nearest: Burke (5 miles west, up to 0.75"); Bonesteel (14 miles northeast, up to 1"); Mills (16 miles southwest, up to 0.75").

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.

For this storm over Herrick, the NWS report log is empty — a common outcome, since ground reports only happen when someone witnesses the hail and takes the time to call it in. The detection record for the date lives in the radar maps above.

Near the severe threshold

What 0.75" hail means for Herrick 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 Sep 8, 2026.
