Evidence / storm surfaces
How Kathryn saw the hail — from two instruments
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 signature field 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.
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 Kathryn's hail record.
This was Kathryn's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 3rd of the 4 storms we have logged here. Radar put the day's largest stone over Kathryn at 1" — the largest NEXRAD radar signature.
The Jun 27, 2026 convective day was bigger than Kathryn: the same system put hail over 587 other tracked cities, 114 of them in North Dakota. Nearest: Litchville (14 miles northwest, up to 0"); Dickey (27 miles west, up to 0"); Gwinner (28 miles south, up to 0").
These maps are stills. In the app this date is one of 4 Kathryn 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.
For this storm over Kathryn, 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.
Damage-capable hail signal
What 1" hail means for Kathryn 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.
