Over the past 24 hours 3-5 inches of snow fell in the mountains around Bozeman and Big Sky. The mountains around West Yellowstone and Cooke City picked up 1-2 inches. At 5 a.m. temperatures are in the teens F and winds are blowing 10-15 mph out of the W-NW. Today, highs will warming into the 20s under mostly cloudy skies and winds will remain light to moderate out of the W-NW. Light snow showers are expected throughout the day and the mountains should pick up an additional 1-3 inches by tomorrow morning. A weak ridge of high pressure builds over the area tomorrow, but another storm is expect to impact the area Sunday and Monday.
Early yesterday morning, lingering snow showers dropped 2” in the Bridger Range and a trace to 1” elsewhere. At 5 a.m. under clear skies, temperatures are colder in the north (single digits) than the south (teens). Winds are SW-NW at 10-15 mph. Later this afternoon a NW flow will bring clouds and scattered snow showers lasting through Thursday. By Friday morning 3-5” are expected in the mountains.
In the last 24 hours Hyalite and Big Sky picked up 5-6” of new snow with 3-4” falling in other areas. At 5 a.m. skies are cloudy and mountain temperatures are in the single digits to low teens. Ridgetop winds are blowing N-NW at 15-20 mph and gusting into the 40s around Cooke City. Snow showers this morning will drop another inch with temperatures climbing toward 20F and winds remaining NW at 20-30 mph.
At 6 a.m. it’s snowing in the mountains. So far Big Sky and the Yellowstone Club have 7-10” with 5” outside West Yellowstone and 3” everywhere else. Mountain temperatures are in the low to mid-teens and winds are out of the southwest to northwest at 15-20 mph. Snowfall will continue and winds will increase today and tonight. By the time the storm will ends tomorrow I estimate another 10” will fall around Big Sky and 4” everywhere else.
At 5 a.m. there’s no new snow to report, just unseasonably warm temperatures and decreasing winds.

Finally, a taste of winter. Snowfall started yesterday afternoon and ended last night. The northern mountains got 6-8” as did Cooke City. The southern mountains and West Yellowstone picked up 4-5”. Winds have been blowing west to northwest at 15-20 mph with gusts of 35 and mountain temperatures are 10-15F. Skies are clearing as a ridge of high pressure moves in. Through Saturday the forecast calls for dry weather and mountain temperatures reaching above freezing. The good news is that unsettled weather is predicted early next week.

The unsettled pattern that dropped snow over southwest Montana has now pushed to the east. This has allowed a ridge of high pressure to build over the area. This ridge will remain stationary for much of the weekend producing sunny skies and warmer temperatures. Highs tomorrow (Saturday) will warm into the upper 30s to low 40s and winds will blow 5-10 mph out of the W-SW. The ridge gradually begins to break down Sunday, producing partly cloudy skies and stronger winds Sunday afternoon. There is a slight chance of rain and snow showers early next week.
Winter has made a welcome appearance. Snowfall totals over the past 48 hours are 6” near Bozeman and Big Sky, 14” near Cooke City, and 16” near West Yellowstone. Wind overnight was out of the northwest at 10-15 mph with gusts near 20 mph. Temperatures this morning are 10-20 F and will reach the mid-20s F today. Wind will be 5-15 mph out of the north to northeast today, and 1-2 more inches of snow will fall before the storm ends this afternoon.
At 0730 many weather stations are reporting fresh snow. The Bridger Range got dusted, the Hyalites are showing 3”, and the Yellowstone Club has 7” as does the southern Madison Range and higher elevations outside Cooke City. The mountains around West Yellowstone received a lot of water (1.5”), but above freezing temperatures kept snowfall amounts under a few inches. Mountain temperatures are near freezing and winds are southeast in the mountains around Bozeman and west to southwest at 20-25 mph everywhere else. The brunt of the storm has passed and drier air today and tomorrow morning will give way to wetter and cooler air Sunday evening.
