Advisory Archive

This morning, mountain temperatures mostly dropped below freezing and are hovering in the upper 20s to low 30s F. Winds are 10-20 mph from the west and the south, and there is no new snow.

Today, the ridge of high pressure breaks down and increasing clouds will start to shade slopes from the constant spring sun. Temperatures in the Bridger Range will peak in the mid-50s F with highs in the mid-40s F throughout the rest of the forecast area. Winds will blow 10-20 mph from the west and southwest, and light snowfall starting tonight will bring 1-2” in the southern portions of the forecast area and a trace to the northern half of the forecast area by morning. 

This morning temperatures are high teens to low 30s F. Wind has been from the southwest and northwest at 5-25 mph with gusts of 25-35 mph. There has been no new snow over the last 24 hours.

Today will be sunny with temperatures reaching high 30s to mid-40s F, 5-10 degrees warmer than yesterday’s high temperatures. Wind will be calm to light, 5-15 mph, out of the west and northwest. Tomorrow looks warmer than today, and tomorrow night colder air brings a chance for light snow showers through Tuesday.

Snow showers yesterday left at most an inch of new snow. Winds are light this morning, out of the north and west. Mountain temperatures this morning are in the single digits and teens F under clear skies.

Today will be sunny and 5 to 10 degrees F warmer than yesterday. High temperatures will be in the 30s and low 40s F. Winds will shift more southwesterly today and remain light.

The next couple days will remain sunny and warm, before clouds and a chance for precipitation return early next week.

New snow totals since yesterday morning are: 

5-7” around Bozeman and Big Sky. 

0-1” everywhere else

Temperatures this morning are in the teens F. Winds are light out of the north and northwest. Except in the Bridger Range, where they’re a little stronger and out of the east.

Snow showers in the north will end this morning, with skies gradually clearing across the whole area by this evening. High temperatures will be in the 20s and 30s F. Wind speeds will pick up a bit this morning, generally blowing from the north.

Expect dry, sunny and warmer conditions through the weekend.

Yesterday most places received 1-3 inches of snow, and overnight a trace of snow fell near Big Sky and Bozeman. Exceptions include:

• The Taylor Fork area where the Carrot Bason SNOTEL received 7 inches. 
• Just south West Yellowstone where the Madison Plateau SNOTEL received zero.
• Near Cooke City, the Fisher Creek SNOTEL received 5 inches.

This morning, temperatures are in the low to mid teens F in most areas and low 20s F in the Bridgers. Winds are barely moving. 

Today will have classic spring weather with a spot or two of sunshine peeking through the clouds this morning warming temperatures into the 20s F, closer to 30 degrees in the Bridgers. Cold air and moisture will descend from the north again. This afternoon winds will become a little gusty as more clouds arrive and snow falls. Overall another 1-3 inches should accumulate, but mostly north of West Yellowstone. A few places could see 5-6 inches of snow and a couple cracks of thunder.

Two more things: (1) A Winter Storm Warning has been issued for the Absaroka/Beartooth mountains today where there could be very heavy snowfall (8-16 inches) mostly on the north slope, and it shouldn’t make it to Cooke City. (2) Looking ahead, the sun comes out Friday and really gets cranking with very warm temps and strong sunshine this weekend…get ready for wet snow.

Snow continued falling yesterday in the mountains near Bozeman and Big Sky with 2-3 inches during the day followed by another 2-3 inches very early this morning.

Snowfall totals since Monday morning:

• Bridger Range - 18” snow (2.2”  water)
• Big Sky - 8-9” snow (0.8” water)
• West Yellowstone and Island Park areas - 7-10” snow (0.7-0.9” water)
• Cooke City areas - 4-6” snow (0.4” water)

This morning, light snow continues to fall near Bozeman and Big Sky. Mountain temperatures are in the mid teens F but closer to 20 degrees F in the Bridgers. Light winds from the west are blowing 5-10 mph gusting in the teens. 

Today moisture descending from the north will continue bringing snow to the northern areas this morning, then to southern parts of the forecast area this afternoon. 1-3 inches should fall in most areas by the end of the day. Cold air will keep high temperatures in the low to mid 20s; however, some sun could appear this afternoon near Bozeman and push high temperatures in the Bridgers closer to freezing. Winds will blow more from the northwest around 10 mph. They may increase a bit mid-morning with gusts in the 20s.

24-Hour Snow Totals (NO JOKE!)

• Bridger Range - 13” of snow (1.4” of snow water equivalent - SWE)
• West Yellowstone and Island Park - 7-10” of snow (0.7-0.9” SWE)
• Big Sky and Cooke City - 4-7” of snow (0.4-0.5” SWE)

This morning, snow is falling heavily, especially in the Bridger Range, and it is expected to continue through tomorrow, with the heaviest accumulation favoring the mountains around Bozeman and Big Sky. Temperatures are in the teens and 20s F with 10-20 mph winds from the west and southwest.

Today, the intensity of the snowfall and wind will be the main drivers of the avalanche danger. The mountains around Bozeman and Big Sky will receive an additional 10-12 inches of snow by tomorrow morning, with 5-8 inches near West Yellowstone, Island Park and Cooke City. Winds will be 10-20 mph from the west shifting to the north, and high temperatures will be in the 20s to low 30s F. 

Since yesterday morning 24 hour snow totals are:

• 2-4” near Bozeman, Big Sky, Cooke City and Island Park

Temperatures are teens to 20s F this morning. Wind was calm most of yesterday, and increased overnight to 10-25 mph with gusts of 25-45 mph out of the south and southwest. 

Today, temperatures will reach mid-30s F with a chance of thunderstorms this afternoon, and wind will be light to moderate out of the southwest and west. Near Island Park, West Yellowstone and Cooke City could get 3-5” of new snow today with another 2-4” in most of the forecast area by tomorrow morning. Heavy snowfall is forecast tomorrow with 1-2 feet possible by Wednesday morning.

Snow totals since yesterday morning are:

Temperatures are below freezing across the whole advisory area for the first time since Monday. There are 2” of new snow in the Bridger Range and a dusting to an inch elsewhere. Winds picked up yesterday afternoon near West Yellowstone and Island Park, gusting 40-55 mph. Winds died down in those areas overnight and are now blowing 5-15 mph out of the west and south across the region. 

Winds today will be light. High temperatures will be substantially cooler than the last couple days, generally in the 30s F. Around Bozeman and Big Sky, skies will be mostly cloudy and snow showers will leave 1-3” by this evening. Near West Yellowstone, Island Park, and Cooke City, expect a mix of sun and clouds, with only a dusting of snowfall. By tomorrow morning, 2-4” will fall across much of the region, with potentially a few more inches in the Big Sky area. 

Several more rounds of snowfall are expected in the coming days.
