Evidence / storm surfaces
How Arvada 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 Aug 26, 2026 — this storm produced no NEXRAD point detections over Arvada, so there is one map to show, not two.
The storm in context
Where Aug 26, 2026 sits in Arvada's hail record.
This was Arvada's 6th recorded hail day, arriving 33 days after the Jul 24, 2026 storm. By severity it ranks 3rd of the 6 storms we have logged here. Radar put the day's largest stone over Arvada at 0.75" — radar-estimated size aloft.
The Aug 26, 2026 convective day was bigger than Arvada: the same system put hail over 440 other tracked cities, 39 of them in Colorado. Nearest: Denver (7 miles south, up to 0.75"); Parker (26 miles southeast, up to 1.75"); Watkins (30 miles southeast, up to 1.75").
These maps are stills. In the app this date is one of 6 Arvada 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 Arvada. 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 Arvada 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.
Potential roof exposure
$246M
Potential roof exposure — 20,527 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 103 jobs
- Illustrative work
- ~$1.5M
Close just 0.5% of the 20,527 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.
Names and phones for every home in the footprint: at most $4,311 on top of the $150 plan.
