Evidence / storm surfaces
How Penrose saw the hail — from two instruments
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.
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.
Only the radar-estimated size surface resolved for Sep 9, 2026 — this storm produced no NEXRAD point detections over Penrose, so there is one map to show, not two.
The storm in context
Where Sep 9, 2026 sits in Penrose's hail record.
This was Penrose's 5th recorded hail day, arriving 14 days after the Aug 26, 2026 storm. By severity it ranks 1st of the 5 storms we have logged here. Radar put the day's largest stone over Penrose at 1.5" — radar-estimated size aloft.
The Sep 9, 2026 convective day was bigger than Penrose: the same system put hail over 71 other tracked cities, 9 of them in Colorado. Nearest: Florence (9 miles southwest, up to 1.5"); Pueblo (17 miles south, up to 2.5"); Beulah (29 miles south, up to 2.25").
These maps are stills. In the app this date is one of 5 Penrose 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.
For this storm over Penrose, the NWS report log is empty — a common outcome, since ground reports only happen when someone witnesses the hail and takes the time to call it in. The detection record for the date lives in the radar maps above.
High damage potential
What 1.5" hail means for Penrose roofs.
Hail around an inch and a half is capable of cracking shingles, stripping granules, and denting gutters, vents, and siding. Risk is usually greatest near the strongest radar signal, but property-level damage still requires an on-site inspection.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$34M
Potential roof exposure — 2,830 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 14 jobs
- Illustrative work
- ~$210K
Close just 0.5% of the 2,830 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
September 2028
Claims from this storm can typically be filed until around September 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 $594 on top of the $150 plan.
