How Emerson saw the hail — from two instruments

Jun 13, 2026 · Emerson, IA

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-estimated hail size Surface resolved
Radar-estimated hail-size map of the storm over Emerson, IA on Jun 13, 2026 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.

Max size 1"

Only the radar-estimated size surface resolved for Jun 13, 2026 — this storm produced no NEXRAD point detections over Emerson, so there is one map to show, not two.

The storm in context

Where Jun 13, 2026 sits in Emerson's hail record.

This was Emerson's 11th recorded hail day, arriving 3 days after the Jun 10, 2026 storm. By severity it ranks 9th of the 15 storms we have logged here. Radar put the day's largest stone over Emerson at 1" — radar-estimated size aloft.

The Jun 13, 2026 convective day was bigger than Emerson: the same system put hail over 587 other tracked cities, 40 of them in Iowa. Nearest: Hastings (11 miles west, up to 1"); Red Oak (15 miles south, up to 1"); Imogene (15 miles south, up to 1").

These maps are stills. In the app this date is one of 15 Emerson 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.

No ground reports were filed with the National Weather Service for this storm over Emerson. That is common: a report depends on someone being there to see it and take the time to call it in. The radar surfaces above are the record here — the storm was detected from above even though no one on the ground logged it.

Damage-capable hail signal

What 1" hail means for Emerson 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.

1,406 homes × $12,000 avg. claim

Potential roof exposure

$17M

Potential roof exposure — 1,406 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

Close just 0.5% of the 1,406 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

June 2028

Claims from this storm can typically be filed until around June 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 $295 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 Sep 15, 2026.
