Heavy Snow in East Glacier Park Region, Montana

Snotel equipment at Many Glacier estimated a change in snow depth of 9 inches between the start and end time.

A deep upper level low centered just off the Pacific Northwest coast combined with remnants of an atmospheric river to result in a period of snow along western portions of the Hi-Line, including the Northern Rocky Mountain Front. Additionally, this moisture and mild temperatures aloft overran a cold surface airmass across Central Montana and resulted in two periods of freezing rain.
