Advisory Archive

Since yesterday morning, 4-6 inches of new snow has accumulated in the Bridger Range, northern Gallatin Range and mountains around Cooke City. The rest of our advisory area picked up 2-3 inches. As the snow moved out the cold temperatures moved in. Currently, mountain temperatures are in the single digits above or below zero and winds are blowing out of the west at 5-15 mph. Today, conditions will remain cold and calm with temperatures struggling to reach the double digits. Winds will stay light out of the west blowing at 5-15 mph under mostly cloudy skies. Snow showers will likely taper this morning with no real accumulations expected over the next 24 hours.      

In the past 24 hours, 3 inches of heavy, dense snow has fallen in the Bridger Range, 2-3 inches has fallen in the mountains around Cooke City, and a trace to an inch has fallen elsewhere. Mountain temperatures are in the mid to high 20s and winds are out of the WSW at 10-20 mph. Today, temperatures will top out around 30 F, but will gradually cool off by this evening as a cold front moves in from the north. Winds will increase from the west as the front approaches, reaching speeds up to 30 mph by this afternoon. Accumulations of 2-4 inches will likely fall throughout our advisory area today, with an additional 2-4 inches falling tonight into tomorrow. 

Warm weather is the word this morning with temperatures mostly in the mid to high 20s F. Westerly ridgetop winds calmed slightly from yesterday blowing 10-25 mph near Bozeman and 5-15 mph elsewhere. Yesterday afternoon some areas received a brief shot of freezing rain followed by a dusting of snow. More precipitation should come this afternoon possibly starting as rain before changing to snow. By tomorrow morning 2-3 inches should accumulate with more on the way. Today will have high temperatures near 30 degrees F with westerly winds blowing 10-15 mph.

An additional inch or two of snow fell in the past 24 hours. This morning temperatures were in the low 20s F at 9000ft except near Cooke City and West Yellowstone where temperatures were closer to 10 degrees F. Only slightly lower elevations have temperatures approaching 30 degrees F. Strong winds yesterday continued this morning blowing 15-30 mph from the W. Warm air advection and tight pressure gradients in the weather models mean today’s weather will be warm and windy with temperatures in the high 20’s to low 30’s and 15-30 mph W winds. Some snowfall is expected, but no more than an inch should accumulate. This weekend, however, looks promising for snow and colder weather.

At 6 a.m. the Yellowstone Club is showing ten inches of new snow. All the other ski areas got six inches with other sites also reading 3-6 inches. Temperatures warmed into the teens as wind speeds increased out of the southwest averaging 20-30 mph with gusts reaching 40-50 mph. Under mostly cloudy skies mountain temperatures will climb into the low 20s today with strong southwest winds. More flurries this morning and again later tonight will drop an additional two to four inches. 

Under clear skies, temperatures this morning are in the single digits with westerly winds blowing 15-25 mph at the ridgetops. Increasing clouds, increasing winds and an increasing chance of precipitation are on our plate for the next 24 hours. A northwest flow will push in clouds later today as mountain temperatures climb into the upper teens and winds blow W-NW at 20-30 mph. By morning the mountains will have 1-3 inches of new snow with showers continuing into Wednesday.  

A moist northwest flow has deposited 8-10 inches of light density snow in the Bridger Range, 2-3 inches in the northern Madison and Gallatin Ranges, and 1-2 inches elsewhere. At 4 am mountain temperatures are in the single digits and winds are blowing out of the W-NW at 5-15 mph with gusts in the 20s. Today snow showers will taper off and temperatures will climb into the high teens under mostly cloudy skies. Winds will continue to blow out of the W-NW at 5-15 mph throughout the day and dry conditions will persist over the next 24 hours.

Under cloudy skies a trace of snow has fallen this morning. In the northern mountains temperatures are in the single digits while around West Yellowstone and Cooke City the temperatures are zero to 10 below. Winds are from the west to northwest averaging 15-20 mph with gusts in the 30s. Today will remain cloudy with temperatures warming into the teens as northwest winds blow 20-30 mph. Small weather disturbances will bring flurries, but accumulations will be less than an inch by tomorrow morning. 

It’s another cold morning with temperatures mostly in the negative single digits F though a few places near West Yellowstone and Cooke City reached the negative teens F. Winds increased since yesterday and were blowing 10-20 mph from the western half of the compass this morning. These winds were mostly confined to ridgetops except in the Bridger Range where they were blowing at all elevations. Today will have partly to mostly sunny skies. High temperatures will be about 10 degree F and winds will blow 10-20 mph from the W and NW. No significant snowfall is expected in the immediate future.

Happy New Year’s Eve! It’s cold this morning and shouldn’t warm up much until next year. Since yesterday only a trace to two inches of new snow fell. Temperatures were in the negative teens F this morning though a bit warmer near West Yellowstone with winds blowing 5-15 mph from the eastern half of the compass. Mostly cloudy skies will prevent much warming and temperatures should rise to near 0 F. Light winds will blow 5-10 mph and shift to the north.
