Hail in Lavina Jul 16, 2026
Hit 18 days agoThe radar-estimated size surface caught this storm, reaching 2" aloft. NEXRAD logged no point detections over Lavina this day. At 2" — tennis ball — this is severe, roof-replacing hail: close to every roof inside the footprint becomes a claim candidate.

How Lavina 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.
Radar-estimated hail size
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 Jul 16, 2026 — this storm produced no NEXRAD point detections over Lavina, so there is one map to show, not two.
Where Jul 16, 2026 sits in Lavina's hail record
This was Lavina's 3rd recorded hail day, arriving 2 days after the Jul 14, 2026 storm. By severity it ranks 2nd of the 3 storms we have logged here. Radar put the day's largest stone over Lavina at 2" — radar-estimated size aloft.
The Jul 16, 2026 convective day was bigger than Lavina: the same system put hail over 206 other tracked cities, 40 of them in Montana. Nearest: Shepherd (24 miles southeast, up to 0.5"); Broadview (24 miles south, up to 0.5"); Acton (25 miles south, up to 0.5").
These maps are stills from Lavina's Jul 16, 2026 storm. In the Overview app the same surfaces are live — radar updating in real time, radar-estimated hail size as it forms, and NWS spotter reports pinned where they're filed — with a radar replay you can scrub back over any past day.

What 2" hail means for Lavina roofs
Two-inch-plus hail punctures shingles, breaks skylights and windows, and dents anything soft. In the core of a footprint like this, close to every roof is a candidate for an insurance claim. Speed decides who writes those jobs.

Other storms in Lavina
A storm day here is a convective day — it runs from noon to noon
UTC, so late-night hail is grouped with the afternoon storm that
spawned it rather than split across two calendar dates. Ground
reports are public-domain observations from the NOAA Storm
Prediction Center. Radar surfaces are detections and estimates,
not confirmed damage. Last updated Aug 3, 2026.
