Hail in Lavina Jul 14, 2026
Hit 20 days agoThe radar-estimated size surface caught this storm, reaching 3.25" aloft. NEXRAD logged no point detections over Lavina this day. At 3.25" — baseball — 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
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.
Radar-estimated hail size
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.
Max size
3.25"
Only the radar-estimated size surface resolved for Jul 14, 2026 — this storm produced no NEXRAD point detections over Lavina, so there is one map to show, not two.
Where Jul 14, 2026 sits in Lavina's hail record
This was Lavina's 2nd recorded hail day, arriving 7 days after the Jul 7, 2026 storm. By severity it ranks 1st of the 3 storms we have logged here. Radar put the day's largest stone over Lavina at 3.25" — radar-estimated size aloft.
The Jul 14, 2026 convective day was bigger than Lavina: the same system put hail over 130 other tracked cities, 23 of them in Montana. Nearest: Ryegate (24 miles west, up to 1.5"); Roundup (30 miles northeast, up to 1.5"); Forest Grove (39 miles north, up to 1.75").
These maps are stills from Lavina's Jul 14, 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 3.25" 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.
