Evidence / storm surfaces
How Dallas Center saw the hail — from two instruments
Apr 17, 2026 · Dallas Center, IA
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.
NEXRAD radar signatures Surface resolved
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.

Radar-estimated hail size Surface resolved
Estimated size field 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.

The storm in context
Where Apr 17, 2026 sits in Dallas Center's hail record.
This was Dallas Center's 3rd recorded hail day, arriving 18 days after the Mar 30, 2026 storm. By severity it ranks 9th of the 9 storms we have logged here. Radar put the day's largest stone over Dallas Center at 0.5" — radar-estimated size aloft.
The Apr 17, 2026 convective day was bigger than Dallas Center: the same system put hail over 1,016 other tracked cities, 201 of them in Iowa. Nearest: Waukee (7 miles south, up to 1.25"); Van Meter (14 miles south, up to 1.5"); Des Moines (15 miles southeast, up to 0.75").

Reports came from Waukee — beyond Dallas Center itself.
Below the severe threshold
What 0.5" hail means for Dallas Center 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 Aug 3, 2026.
