Evidence / storm surfaces
How Weldon saw the hail — from two instruments
Apr 23, 2026 · Weldon, 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.

Only the NEXRAD radar-signature surface resolved for Apr 23, 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 Apr 23, 2026 sits in Weldon's hail record.
This was Weldon's 3rd recorded hail day, arriving 6 days after the Apr 17, 2026 storm. By severity it ranks 4th of the 6 storms we have logged here. Radar put the day's largest stone over Weldon at 1" — the largest NEXRAD radar signature.
The Apr 23, 2026 convective day was bigger than Weldon: the same system put hail over 703 other tracked cities, 252 of them in Iowa. Nearest: Osceola (7 miles north, up to 1"); Grand River (10 miles west, up to 0"); Murray (13 miles northwest, up to 0").
These maps are stills. In the app this date is one of 6 Weldon 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.

Damage-capable hail signal
What 1" hail means for Weldon 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.

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 5, 2026.
