How Harlan saw the hail — from two instruments

Sep 6, 2026 · Harlan, IA

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 map of the storm over Harlan, IA on Sep 6, 2026 — 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 Sep 6, 2026 — this storm produced no NEXRAD point detections over Harlan, so there is one map to show, not two.

The storm in context

Where Sep 6, 2026 sits in Harlan's hail record.

This was Harlan's 9th recorded hail day, arriving 24 days after the Aug 13, 2026 storm. By severity it ranks 4th of the 9 storms we have logged here. Radar put the day's largest stone over Harlan at 1" — radar-estimated size aloft.

Damage-capable hail signal

What 1" hail means for Harlan 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.

1,979 homes × $12,000 avg. claim

Potential roof exposure

$24M

Potential roof exposure — 1,979 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

Illustrative jobs: 10 jobs
Illustrative work: ~$150K

Close just 0.5% of the 1,979 homes in this footprint at the average $15,000 roof job. Illustrative math, not a projection — your results depend on your outreach and how the market responds.

Claim window

September 2028

Claims from this storm can typically be filed until around September 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.

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 7, 2026.
