Both radar surfaces caught this storm: NEXRAD logged 0 hail signatures up to 0", and the radar-estimated size reached 0.5" aloft.
A tornado was also reported to the National Weather Service during this storm — see the ground reports below.

Largest hailstone — the top predictor of roof damage.
How many homes sit inside the storm's footprint.
Independent storm reports filed with the NWS.
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.
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.
This was Marshall's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 5th of the 5 storms we have logged here. Radar put the day's largest stone over Marshall at 0.5" — radar-estimated size aloft.
The Apr 26, 2026 convective day was bigger than Marshall: the same system put hail over 710 other tracked cities, 278 of them in Missouri. Nearest: Malta Bend (11 miles northwest, up to 0.5"); Slater (15 miles north, up to 0.5"); Miami (18 miles north, up to 1.75").
These maps are stills from Marshall's Apr 26, 2026 storm. In the Overview app the same surfaces are live — radar updating in real time, radar-estimated hail size as it forms, and NWS spotter reports pinned where they're filed — with a radar replay you can scrub back over any past day.
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.
“Corrects previous tornado report from 5 W Slater. A tornado developed near Bluebird Trail southwest of Slater at 652 am on April 27... producing sporadic tree damage as (EAX)”
— NOAA / SPC storm report
Reports came from Slater — beyond Marshall itself.
Hail under three-quarters of an inch stays below the National Weather Service severe threshold and rarely breaks shingles outright. But repeated small-hail events accelerate granule loss and shorten roof life — on older roofs, it's still worth a conversation.
