A record-smashing snowstorm with wet snow and strong winds hit parts of the Northern Rockies on September 28 and 29, 2019, resulting in power outages, uprooted trees, and road closures. Several parts of Montana experienced blizzard conditions and more than a foot of snow, setting new daily rainfall records. Wind gusts from 40 to 60 mph were measured in Montana.
AccuWeather Senior Meteorologist Alex Sosnowski explained the cause behind the historic snowfall, saying "the combination of a storm from the Pacific Ocean, a fresh injection of cold air from northern Canada, moisture from the Gulf of Mexico and a northeast-ascending flow that squeezed extra moisture from the atmosphere produced the amazing snowfall."
The highest snowfall was recorded in Browning, Montana with a total of 4 feet. Meanwhile, East Glacier Park received 2 feet of snow.
It beat the daily record of 6.1 inches set in 1954. With a total of 19.3 inches, the two-day record came second to that of April 27 to 28 in 2009, with 24.2 inches, which was the city's heaviest snowfall in two days.
It usually takes until a week before Christmas for the area to have a total of 19.3 inches of snowfall in an average winter.
Blizzard conditions were experienced across the northern and southern Rocky Mountain front, including at the Cut Bank, Montana, Airport where there was moderate to heavy snowfall with sustained winds of 30 mph on September 29.
