Heavy Snow — Gallatin and Madison County Mountains and Centennial Mountains, Montana

2024-12-29 · Gallatin and Madison County Mountains and Centennial Mountains, Montana

Event narrative

Snotel equipment at Black Bear estimated 10 inches new snow.

Wider weather episode

Warm air advection aloft in advance of an approaching Pacific trough allowed for mainly light, but localized heavy snow to develop across the region December 29th into the 30th. A band of snow developed across Southwest Montana early in the event and progressed northward, but never stalled anywhere for too long, thus only resulting in localized heavy snow reports.
