Evidence / storm surfaces
How Oakville saw the hail — from two instruments
The maps here read the same storm from two angles — point detections from NEXRAD, and modeled hail size aloft. Where the two disagree is informative: it marks where estimated size outran the signatures, or trailed them.
Radar signature field Where NEXRAD flagged hail as the storm passed — point signatures from the radar, which indicate hail overhead rather than confirm what landed.
Only the NEXRAD radar-signature surface resolved for Mar 30, 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 Mar 30, 2026 sits in Oakville's hail record.
This was Oakville's 3rd recorded hail day, arriving 4 days after the Mar 26, 2026 storm. By severity it ranks 8th of the 10 storms we have logged here. Radar put the day's largest stone over Oakville at 1" — the largest NEXRAD radar signature.
The Mar 30, 2026 convective day was bigger than Oakville: the same system put hail over 313 other tracked cities, 78 of them in Iowa. Nearest: Mediapolis (10 miles west, up to 1"); Yarmouth (16 miles west, up to 0"); Muscatine (21 miles north, up to 1").
These maps are stills. In the app this date is one of 10 Oakville 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.
Nobody on the ground filed a report over Oakville for this date, which says more about who was watching than about the storm: spotter reports only exist where there is an observer. The radar surfaces above carry the evidence for this one.
Damage-capable hail signal
What 1" hail means for Oakville 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.
