Evidence / storm surfaces
How Rockville 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 6, 2026 — this storm produced no NEXRAD point detections over Rockville, so there is one map to show, not two.
The storm in context
Where Sep 6, 2026 sits in Rockville's hail record.
This was Rockville's 7th recorded hail day, arriving 32 days after the Aug 5, 2026 storm. By severity it ranks 7th of the 7 storms we have logged here. Radar put the day's largest stone over Rockville at 0.75" — radar-estimated size aloft.
The Sep 6, 2026 convective day was bigger than Rockville: the same system put hail over 608 other tracked cities, 45 of them in Missouri. Nearest: Appleton City (7 miles north, up to 0.75"); Schell City (7 miles south, up to 0.75"); Butler (18 miles northwest, up to 0.5").

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.
The National Weather Service logged no spotter reports for this storm over Rockville. That absence is ordinary — filing a report takes a person on the spot who saw the hail and phoned it in. What stands as the record for this date is the radar above, which caught the storm regardless.
Near the severe threshold
What 0.75" hail means for Rockville 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
$2M
Potential roof exposure — 170 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 170 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
