Evidence / storm surfaces
How Scarborough saw the hail — from two instruments
We map this storm two ways: the NEXRAD radar signatures the storm produced overhead, and the radar-estimated size of the hail in the air. The two surfaces don’t have to match — where they diverge is where estimated size aloft ran ahead of, or behind, what the signatures caught.
Estimated size field Maximum hail size as estimated from radar aloft. Treat it as the storm's ceiling — the largest supportable stone — rather than a ground measurement.
Only the radar-estimated size surface resolved for Aug 13, 2026 — this storm produced no NEXRAD point detections over Scarborough, so there is one map to show, not two.
The storm in context
Where Aug 13, 2026 sits in Scarborough's hail record.
This was Scarborough's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 1st of the 1 storms we have logged here. Radar put the day's largest stone over Scarborough at 1" — radar-estimated size aloft.
The Aug 13, 2026 convective day was bigger than Scarborough: the same system put hail over 437 other tracked cities, 7 of them in Maine. Nearest: Portland (7 miles north, up to 1"); South China (65 miles northeast, up to 0.5"); Union (67 miles northeast, up to 1").

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.

Storm forensics
How the storm moved
Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.
Reports came from Portland Jetport — beyond Scarborough itself.
Damage-capable hail signal
What 1" hail means for Scarborough roofs.
Quarter-size and larger hail can bruise asphalt mats, remove granules, and dent exposed soft metal. The mapped footprint identifies an inspection priority area — it does not identify which individual roofs, if any, sustained damage.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$172M
Potential roof exposure — 14,296 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 71 jobs
- Illustrative work
- ~$1.1M
Close just 0.5% of the 14,296 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 $3,002 on top of the $150 plan.
