Evidence / storm surfaces
How Havre 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 Aug 23, 2026 — this storm produced no NEXRAD point detections over Havre, so there is one map to show, not two.
The storm in context
Where Aug 23, 2026 sits in Havre's hail record.
This was Havre'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 Havre at 1.5" — radar-estimated size aloft.
The Aug 23, 2026 convective day was bigger than Havre: the same system put hail over 185 other tracked cities, 18 of them in Montana. Nearest: Kremlin (14 miles west, up to 1.5"); Gildford (23 miles west, up to 1.25"); Hingham (31 miles west, up to 1.25").

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 12 minutes, from to .
High damage potential
What 1.5" hail means for Havre roofs.
Hail around an inch and a half is capable of cracking shingles, stripping granules, and denting gutters, vents, and siding. Risk is usually greatest near the strongest radar signal, but property-level damage still requires an on-site inspection.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$4.7M
Potential roof exposure — 389 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 2 jobs
- Illustrative work
- ~$30K
Close just 0.5% of the 389 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.
