In the last 24 hours no new snow fell. Mountain temperatures slowly climbed to 10F, except in Cooke City and West Yellowstone where they are anchored near zero. West to southwest winds are blowing 15-25 mph under partly cloudy skies. Clouds will blanket us completely by late morning as wind speeds increase out of the southwest and gust into the 30s. Mountain temperatures will reach the high teens with scattered snow falling late this afternoon. By morning 2-4 inches are expected with more accumulating on Thursday.
Under partly cloudy skies mountain temperatures are a few degrees below zero with light westerly winds averaging 10-15 mph. Today temperatures will break the zero degree mark and warm into the upper single digits; not exactly balmy, but a warming trend non-the-less. Clouds and wind speeds will increase this afternoon although no snow is expected for the next 24 hours.
Frigid cold temperatures are the word this morning with most mountain locations reading 5-10 below zero F. Fortunately winds are light, blowing out of the WSW at 5-15 mph. Mountain temperatures will fight to break zero today with highs reaching 5-10 above. Winds will stay light out of the WSW under partly to mostly cloudy skies. Temperatures will plunge back to double digits below zero tonight, with a gradual warming trend starting tomorrow.
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.
