Evidence / storm surfaces
How Newcastle saw the hail — from two instruments
Two instruments, one storm: NEXRAD logs the point signatures it detected overhead, while the estimated-size surface models how large the hail aloft could have grown. Agreement between them is not guaranteed — the gaps are where the model ran ahead of, or behind, the detections.
Estimated size field Radar-estimated maximum hail size across the swath, modeled from radar aloft. It reflects the biggest stone the storm could support, which may differ from what actually fell.
Only the radar-estimated size surface resolved for Sep 18, 2026 — this storm produced no NEXRAD point detections over Newcastle, so there is one map to show, not two.
The storm in context
Where Sep 18, 2026 sits in Newcastle's hail record.
This was Newcastle's 15th recorded hail day, arriving 12 days after the Sep 6, 2026 storm. By severity it ranks 14th of the 16 storms we have logged here. Radar put the day's largest stone over Newcastle at 0.75" — radar-estimated size aloft.
The Sep 18, 2026 convective day was bigger than Newcastle: the same system put hail over 157 other tracked cities, 1 of them in Wyoming. Nearest: Harrison (84 miles south, up to 1.75"); Glendo (88 miles south, up to 0.5"); Crawford (91 miles southeast, up to 1.75").

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 Newcastle. 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 Newcastle 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
$912K
Potential roof exposure — 76 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
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.
