Evidence / storm surfaces
How Marengo 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.
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.
Only the radar-estimated size surface resolved for Jun 11, 2026 — this storm produced no NEXRAD point detections over Marengo, so there is one map to show, not two.
The storm in context
Where Jun 11, 2026 sits in Marengo's hail record.
This was Marengo's 6th recorded hail day, arriving 24 days after the May 18, 2026 storm. By severity it ranks 7th of the 10 storms we have logged here. Radar put the day's largest stone over Marengo at 0.5" — radar-estimated size aloft.
The Jun 11, 2026 convective day was bigger than Marengo: the same system put hail over 648 other tracked cities, 147 of them in Iowa. Nearest: Williamsburg (11 miles south, up to 0.5"); Brooklyn (13 miles west, up to 0.75"); Montezuma (21 miles southwest, up to 0.75").
These maps are stills. In the app this date is one of 10 Marengo 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.
No ground reports were filed with the National Weather Service for this storm over Marengo. 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.
Below the severe threshold
What 0.5" hail means for Marengo roofs.
Radar signals under three-quarters of an inch stay below the National Weather Service severe threshold and generally indicate lower roof risk. Older or already-worn materials can still show effects, but radar alone cannot determine whether a specific roof was damaged.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$2.3M
Potential roof exposure — 194 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 1 job
- Illustrative work
- ~$15K
Close just 0.5% of the 194 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 $41 on top of the $150 plan.
