Evidence / storm surfaces
How Portland 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.
Radar signature field The point detections NEXRAD recorded overhead. Each signature marks where the radar saw hail aloft — it is a detection, not a stone measured on the ground.
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.
The storm in context
Where Mar 26, 2026 sits in Portland's hail record.
This was Portland's 2nd recorded hail day, arriving 4 days after the Mar 22, 2026 storm. By severity it ranks 1st of the 8 storms we have logged here. Radar put the day's largest stone over Portland at 2.5" — the largest NEXRAD radar signature.
The Mar 26, 2026 convective day was bigger than Portland: the same system put hail over 316 other tracked cities, 80 of them in Indiana. Nearest: Pennville (5 miles west, up to 2.5"); Geneva (9 miles northeast, up to 2.5"); Fort Recovery (13 miles southeast, up to 3.25").
These maps are stills. In the app this date is one of 8 Portland 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.

Storm forensics
How the storm moved
Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.
Hail was reported over 25 minutes, from to .
Reports came from Bryant — beyond Portland itself.
Severe hail signal
What 2.5" hail means for Portland roofs.
Two-inch-plus hail is capable of puncturing shingles, breaking skylights or windows, and heavily denting soft materials. The strongest radar bands warrant prompt inspection, but neither the signal nor the footprint confirms damage at a specific address.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$6M
Potential roof exposure — 501 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 3 jobs
- Illustrative work
- ~$45K
Close just 0.5% of the 501 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
March 2028
Claims from this storm can typically be filed until around March 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 $105 on top of the $150 plan.
