How Mandaree saw the hail — from two instruments
Aug 23, 2026 · Mandaree, ND
Two instruments, one storm: NEXRAD logs the point signatures it detected overhead, while the estimated-size surface models how large the hail aloft could have grown. Agreement between them is not guaranteed — the gaps are where the model ran ahead of, or behind, the detections.

The storm in context
Where Aug 23, 2026 sits in Mandaree's hail record.
This was Mandaree's 5th recorded hail day, arriving 49 days after the Jul 5, 2026 storm. By severity it ranks 1st of the 7 storms we have logged here. Radar put the day's largest stone over Mandaree at 2.5" — radar-estimated size aloft.
The Aug 23, 2026 convective day was bigger than Mandaree: the same system put hail over 185 other tracked cities, 20 of them in North Dakota. Nearest: New Town (25 miles north, up to 1"); Plaza (34 miles northeast, up to 0.5"); Berthold (53 miles northeast, up to 0.75").

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.
Wind reports
1 reportSevere hail signal
What 2.5" hail means for Mandaree roofs.
Two-inch-plus hail is capable of puncturing shingles, breaking skylights or windows, and heavily denting soft materials. The strongest radar bands warrant prompt inspection, but neither the signal nor the footprint confirms damage at a specific address.

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 7, 2026.
