A historic September snowstorm blasted parts of the northern Rockies with heavy, wet snow and high winds, leading to power outages and tree damage, and was accompanied by record-cold temperatures for the end of September and early October.

Over a dozen locations in northern Montana picked up over a foot of snow. The highest snowfall total was 48 inches (4 feet) in Browning, Montana, about 105 miles northwest of Great Falls. East Glacier Park had measured 24 inches of snow.

In Great Falls, Montana, this snowstorm not only shattered September records, but it was also one of their heaviest snowstorms of all time.

Sept. 28 (9.7 inches) and Sept. 29 (9.6 inches) were the two heaviest September snowfall days on record in the city. The two-day total of 19.3 inches was second only to April 27-28, 2009 (24.2 inches) for the city's all-time heaviest two-day snowfall, the National Weather Service in Great Falls tweeted.

In an average winter season, it takes until the week before Christmas for Great Falls to tally 19.3 inches of seasonal snowfall.
