How Gibson saw the hail — from two instruments

Sep 8, 2026 · Gibson, 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
Map image is still rendering for this surface.

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 0.75"

Only the radar-estimated size surface resolved for Sep 8, 2026 — this storm produced no NEXRAD point detections over Gibson, so there is one map to show, not two.

The storm in context

Where Sep 8, 2026 sits in Gibson's hail record.

This was Gibson's 3rd recorded hail day, arriving 29 days after the Aug 10, 2026 storm. By severity it ranks 2nd of the 3 storms we have logged here. Radar put the day's largest stone over Gibson at 0.75" — radar-estimated size aloft.

The Sep 8, 2026 convective day was bigger than Gibson: the same system put hail over 62 other tracked cities, 35 of them in Iowa. Nearest: Barnes City (5 miles west, up to 0.75"); Keswick (5 miles east, up to 0.5"); Brooklyn (14 miles north, up to 0.5").

These maps are stills. In the app this date is one of 3 Gibson 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 Gibson. 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.

Near the severe threshold

What 0.75" hail means for Gibson roofs.

A signal this size sits near the National Weather Service severe threshold. Aging shingles and soft metals such as vents, flashing, and gutters may be more vulnerable; roof age, wind, and material condition all matter, and only an inspection can confirm 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 9, 2026.
