Brutus is forming in response to an usually large loop in the jet stream over the Western U.S.

Right on the heels of Winter Storm Athena comes Winter Storm Brutus--a powerful low pressure system that is taking shape over Southern Montana this morning. Light snows have begun in Southwest Montana, and will spread to the northwest across much of Montana and into western North Dakota this afternoon through Saturday.

As much as 12” to 18” of snowfall is expected for several major cities in Montana, including Great Falls, and over 2 feet is expected in the mountains. According to the Glasgow, MT NWS Facebook page, the current storm total snowfall amounts north of the Missouri River/Fort Peck areas would be within the top 10 two day snowfall totals across this region, going back 115 years.

Strong winds will combine with heavy snowfall to produce blizzard conditions across northeast Montana. Brutus is forming in response to an usually large loop in the jet stream over the Western U.S. On the east side of the jet stream axis, a southwesterly flow of air has pumped in record-breaking warm air from the Desert Southwest. Sheridan, Wyoming hit 79°F Wednesday, breaking their previous all-time monthly record of 78° set on Nov. 5, 1975. Records go back to 1893. However, Sheridan will be on the west side of jet stream by Saturday, as the cold front associated with Brutus passes through Wyoming. This will bring Sheridan powerful northwest winds, 4 - 8 inches of snow, and high temperatures 50° colder than Wednesday's.

I know why the Weather Underground wants to use names, but until the National Weather Service agrees to do so, make it clear that such names are NOT official and is just what one private company is using.
