Evidence / storm surfaces
How Lowden saw the hail — from two instruments
Aug 7, 2026 · Lowden, IA
Each storm gets two readings: the radar signatures NEXRAD recorded as the cells passed overhead, and a modeled estimate of hail size in the air. They are independent surfaces, so a mismatch between them is expected — and worth reading.
Radar-estimated hail size Surface resolved
Estimated size field Radar-estimated hail size over the swath. The model reports the biggest stone the storm could sustain in the air; what actually fell may have been smaller.
Max size
0.75"
Only the radar-estimated size surface resolved for Aug 7, 2026 — this storm produced no NEXRAD point detections over Lowden, so there is one map to show, not two.
The storm in context
Where Aug 7, 2026 sits in Lowden's hail record.
This was Lowden's 4th recorded hail day, arriving 35 days after the Jul 3, 2026 storm. By severity it ranks 2nd of the 5 storms we have logged here. Radar put the day's largest stone over Lowden at 0.75" — radar-estimated size aloft.
The Aug 7, 2026 convective day was bigger than Lowden: the same system put hail over 709 other tracked cities, 114 of them in Iowa. Nearest: Stanwood (10 miles west, up to 1"); Olin (12 miles northwest, up to 1"); Mechanicsville (18 miles west, up to 1").
These maps are stills. In the app this date is one of 5 Lowden 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.

Near the severe threshold
What 0.75" hail means for Lowden 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.

Roofing exposure
What this storm is worth to a roofer.
978 homes × $12,000 avg. claim
Potential roof exposure
$12M
Potential roof exposure — 978 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.

Close just 0.5% of the 978 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
August 2028
Claims from this storm can typically be filed until around August 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 Aug 22, 2026.
