Hail — Musselshell, Montana

2024-06-27 · near Roundup, Musselshell, Montana

Wider weather episode

An unstable southwest flow aloft was over the Billings Forecast Area. Large-scale ascent ahead of a midlevel trough tracked eastward across the northern Rockies. Thunderstorms developed over the mountains of southwest Montana and moved east onto the adjacent plains. Wind shear of around 50kts supported storm organization resulting in organized thunderstorm clusters and supercells, some of which produced large hail and severe outflow winds.
