How Arlington saw the hail — from two instruments

Jun 9, 2026 · Arlington, 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 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 0.5"

Only the radar-estimated size surface resolved for Jun 9, 2026 — this storm produced no NEXRAD point detections over Arlington, so there is one map to show, not two.

The storm in context

Where Jun 9, 2026 sits in Arlington's hail record.

This was Arlington's 2nd recorded hail day, arriving 5 days after the Jun 4, 2026 storm. By severity it ranks 6th of the 8 storms we have logged here. Radar put the day's largest stone over Arlington at 0.5" — radar-estimated size aloft.

The Jun 9, 2026 convective day was bigger than Arlington: the same system put hail over 646 other tracked cities, 67 of them in South Dakota. Nearest: Rutland (9 miles southeast, up to 0.5"); Howard (28 miles southwest, up to 0.75"); Dell Rapids (28 miles southeast, up to 0.5").

These maps are stills. In the app this date is one of 8 Arlington 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.

For this storm over Arlington, 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.

Below the severe threshold

What 0.5" hail means for Arlington roofs.

Radar signals under three-quarters of an inch stay below the National Weather Service severe threshold and generally indicate lower roof risk. Older or already-worn materials can still show effects, but radar alone cannot determine whether a specific roof was damaged.

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 12, 2026.
