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.

The final storm of 2010 deposited an additional 7-8 inches of snow in most areas except near West Yellowstone where an additional 10-12 inches fell since yesterday morning. Although light snowfall will continue today, only an inch or two should accumulate. This morning temperatures had dropped to the single digits F near West Yellowstone and around -5 degrees F everywhere else. Winds were blowing 5-15 mph from the N and E. Today temperatures should drop further to almost -10 degrees F with cold E and NE winds blowing 10-15 mph.

Snow is falling this morning and will continue into tonight. At 6 a.m. 8-10 inches fell around West Yellowstone; 5-7 inches around Cooke City and the Big Sky area; and 2-4 inches in the Bridger Range and Hyalite. Winds have increased out of the southwest at 20-40 mph with mountain temperatures in the teens. Snowfall will continue today and taper off tonight as temperatures dive to near zero by tomorrow morning. I expect another 3-6 inches to fall in the north and 6-10 inches in the southern ranges. Southwest winds will remain moderate throughout the storm.   

In the past 24 hours an inch of new snow has fallen from the Yellowstone Club to West Yellowstone while Cooke City got three inches. Winds have lessened to 15-30 mph out of the WSW from yesterdays breezy 35-50 mph. Temperatures are in the low teens which is where they will remain today. A moist southwest flow will bring mostly cloudy skies with the southern half of our advisory area getting an inch or two of snow overnight. An approaching cold front will increase winds tonight with snow and plummeting temperatures forecasted tomorrow.   

Since yesterday afternoon a surprise storm has deposited 6-8 inches of snow in the mountains around Big Sky, West Yellowstone and Cooke City. The Bridger Range and northern Gallatin Range picked up 2-3 inches. Winds have been blowing out of the W-SW at 15-30 mph with gusts reaching close to 40 mph in Hyalite and Cooke City. Mountain temperatures are currently in the mid-teens to mid-twenties F and will rise into the low 30’s F by this afternoon. Winds will remain strong today out of the west delivering light bands of moisture to southwest Montana. An additional 1-2 inches of snow is possible by this afternoon. A more potent storm is forecasted to impact our area Wednesday and Thursday.

A strong southwest flow is keeping temperatures warm and is producing gusty ridgetop winds. Currently, mountain temperatures are hovering around freezing, with the exception a few locations in the north where temperatures have climbed into the 40’s F. Winds are blowing out of the W-SW at 15-30 mph with gusts over 50 mph being recorded at the Hyalite weather station. Today, temperatures will climb into the 40’s under mostly cloudy skies and winds will remain strong out of the SW. The mountains around West Yellowstone and Cooke City could see a few light snow showers this afternoon, but the no real accumulations are expected.

A ridge of high pressure has produced perfect flying conditions for Santa. This morning mountain temperatures are in the mid-twenties to low thirties F and wind are blowing out of the W-SW at 10-25 mph, with the exception of the Big Sky where they are blowing closer to 30 with gusts up to 50 mph. Today, a strong southwest flow will raise temperatures into the high thirties F and winds will stay gusty out of the W-SW. Despite a little wind, today should be a warm and beautiful day to get out and play with the new toys.
