Evidence / storm surfaces
How New England 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.
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 Sep 23, 2026 — this storm produced no NEXRAD point detections over New England, so there is one map to show, not two.
The storm in context
Where Sep 23, 2026 sits in New England's hail record.
This was New England's 13th recorded hail day, arriving 19 days after the Sep 4, 2026 storm. By severity it ranks 4th of the 13 storms we have logged here. Radar put the day's largest stone over New England at 1.25" — radar-estimated size aloft.
The Sep 23, 2026 convective day was bigger than New England: the same system put hail over 29 other tracked cities, 8 of them in North Dakota. Nearest: South Heart (18 miles north, up to 3"); Reeder (25 miles south, up to 0.75"); Belfield (28 miles northwest, up to 2.5").
These maps are stills. In the app this date is one of 13 New England 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.
Hail reports
1 reportDamage-capable hail signal
What 1.25" hail means for New England 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
$1.4M
Potential roof exposure — 118 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 118 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 $25 on top of the $150 plan.
