Winter is working hard to make an appearance. Over the past 24 hours most mountain locations picked up 3-5 inches of low density snow with the exception of the mountains near West Yellowstone which picked up around one inch. Temperatures are also the coldest they have been in weeks. At 4 am, mountain temperatures are in the single digits to mid-teens F and winds are light out of N-NW. Today, a northwest flow aloft will continue to produce light snow showers in the mountains, although no real accumulation is expected. Temperatures will warm into the upper teens to mid-20s F and winds will remain light out of N-NW. Winter will try and stick around until tomorrow then spring like conditions return on Wednesday.
Overnight the northern Gallatin Range picked up 1” of new snow while the rest of the advisory area remained dry. This morning, mountain temperatures are actually below freezing and range from the upper teens to mid-20s F under partly to mostly cloudy skies. Winds are blowing 10-20 mph out of the W-NW. Today, skies will remain partly to mostly cloudy and temperatures will warm into the upper 20s to low 30s F. Winds will continue to blow 10-20 mph out of the W-NW. No accumulating snowfall is expected over the course of the day. There is a better chance of precipitation tonight and tomorrow. The mountains should receive 1-3” of snow by tomorrow afternoon.
Spring like weather continues around southwest Montana. At 4 am temperatures range from the upper 20s to upper 30s F and winds are blowing 10-20 out of the W with gusts around Big Sky reaching 30 mph. Today, near record highs are possible around much of the region. By this afternoon mountain temperatures will warm into the mid to upper 40s F under partly to mostly cloudy skies. Winds will continue to blow 10-15 mph out of the W-NW with stronger gusts possible in upper elevation terrain. A weak storm system is approaching from the west which will produce increasing clouds throughout the day. Light rain and snow showers are possible in the mountains by late afternoon. The mountains could pick up 1-2 inches of snow by tomorrow morning.

Mountain temperatures are in the low to mid 20s with winds out of the west to southwest averaging 20 mph and gusting to 30 mph. Today will remain windy at the ridgetops as temperatures climb to the upper 20s and snow falls. I expect 2-4 inches of new snow in the mountains with closer to six inches around Cooke City before skies clear tonight.
