2025-02-01 · Southern Rocky Mountain Front, Montana

Event narrative

Snotel equipment at Copper Camp estimated a chance in snow depth of 9 inches between 4 PM Jan 31 and 1 PM Feb 1.

Wider weather episode

A period of gusty winds and locally heavy snow spanned two months (January and February) associated with an upper level low the dug southward from the Gulf of Alaska toward Vancouver Island. Ahead of the system a period of strong westerly to southwesterly mid level flow set the stage for a period of gusty winds across commonly windy areas over the plains (Rocky Mountain Front, MT200 corridor), in addition to the Madison River Valley and adjacent areas. Areas of snow developed between two separate waves within the digging trough, which brought a localized heavy snow report along the Southern Rocky Mountain Front.
