Evidence / storm surfaces
How Kirkwood saw the hail — from two instruments
May 4, 2026 · Kirkwood, IL
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.
NEXRAD radar signatures Surface resolved
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.

Radar-estimated hail size Surface resolved
Estimated size field The modeled maximum hail size across the swath, derived from radar aloft — the largest stone the storm could have supported, which is not necessarily what reached the ground.

The storm in context
Where May 4, 2026 sits in Kirkwood's hail record.
This was Kirkwood's 3rd recorded hail day, arriving 17 days after the Apr 17, 2026 storm. By severity it ranks 3rd of the 5 storms we have logged here. Radar put the day's largest stone over Kirkwood at 1" — the largest NEXRAD radar signature.
The May 4, 2026 convective day was bigger than Kirkwood: the same system put hail over 428 other tracked cities, 239 of them in Illinois. Nearest: Oquawka (9 miles northwest, up to 1.75"); Roseville (9 miles southeast, up to 1"); Monmouth (9 miles southeast, up to 1").
These maps are stills. In the app this date is one of 5 Kirkwood 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 Kirkwood 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.

Roofing exposure
What this storm is worth to a roofer.
39 homes × $12,000 avg. claim
Potential roof exposure
$468K
Potential roof exposure — 39 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
Claim window
May 2028
Claims from this storm can typically be filed until around May 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.
Names and phones for every home in the footprint: at most $8 on top of the $150 plan.

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 2, 2026.
