Evidence / storm surfaces

How Mulvane saw the hail — from two instruments

May 18, 2026 · Mulvane, KS

We map this storm two ways: the NEXRAD radar signatures the storm produced overhead, and the radar-estimated size of the hail in the air. The two surfaces don’t have to match — where they diverge is where estimated size aloft ran ahead of, or behind, what the signatures caught.

Radar-estimated hail size Surface resolved
Radar-estimated hail-size map of the storm over Mulvane, KS on May 18, 2026 Estimated size field

Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.

Max size 1"

Only the radar-estimated size surface resolved for May 18, 2026 — this storm produced no NEXRAD point detections over Mulvane, so there is one map to show, not two.

The storm in context

Where May 18, 2026 sits in Mulvane's hail record.

This was Mulvane's 4th recorded hail day, arriving 31 days after the Apr 17, 2026 storm. By severity it ranks 5th of the 14 storms we have logged here. Radar put the day's largest stone over Mulvane at 1" — radar-estimated size aloft.

The May 18, 2026 convective day was bigger than Mulvane: the same system put hail over 726 other tracked cities, 258 of them in Kansas. Nearest: Peck (5 miles west, up to 1"); Wichita (7 miles north, up to 1"); Belle Plaine (7 miles south, up to 1.25").

These maps are stills. In the app this date is one of 14 Mulvane 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

No reports filed with the NWS

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.

For this storm over Mulvane, the NWS report log is empty — a common outcome, since ground reports only happen when someone witnesses the hail and takes the time to call it in. The detection record for the date lives in the radar maps above.

Damage-capable hail signal

What 1" hail means for Mulvane 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.

3,787 homes × $12,000 avg. claim

Potential roof exposure

$45M

Potential roof exposure — 3,787 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed 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 Sep 10, 2026.
