Heavy Snow in Southern Rocky Mountain Front, Montana

SNOTEL equipment at Wood Creek estimated 10 inches of new snow over the duration of the event.

Shortwaves traversing a broader longwave trough across much of the western CONUS brought a round of snow to the region. Most impacts came in/near mountains and across the plains generally west of I-15. Isentropic ascent combined with northwesterly surface winds to result in heavy and blowing snow, especially along the Northern Rocky Mountain front, where short-term (Less than 3 hrs) of whiteout conditions were observed.
