Under clear skies, mountain temperatures range from 12 to 20 degrees above zero. West to northwest winds have increased from 10-15 mph yesterday morning to 20-30 mph. They will get even stronger this afternoon as the high pressure ridge flattens and clouds appear. Tonight, temperatures will fall into the low teens and scattered snowfall will measure a trace to one inch by morning. A strong northwest flow builds tomorrow and the weather models show a snowy weekend. My fingers are crossed.
With temperatures of zero this morning I’m betting the groundhog is a no-show. Today will be a beautiful winter day with sunny skies, mountain temperatures rising into the teens and north to northwest winds blowing 10-20 mph. High pressure continues to dominate our weather pattern. Tonight, clear skies will help the temperatures plummet to below zero and warm up even more tomorrow.
Brrrr. After getting used to the warm weather last week, this morning’s mountain temperatures are downright nasty. Minus 16 to minus 20 is the average with clear skies and light northerly winds at 5-15 mph. Today will be sunny, but cold. Temperatures will rise into the low single digits before plummeting again tonight to minus 15 or minus 20; is there really a difference? High pressure, clear skies and temperatures in the teens are forecasted for tomorrow with a warming trend all week.
Over the past 24 hours, 2-3 inches of low density snow has fallen in the mountains around Cooke City, while the rest of our advisory area picked up 1-2 inches. Temperatures have been on the decline as a cold arctic air mass continues to work its way into southwest Montana. Currently, mountain temperatures are ranging from -10 F on the ridge at Bridger Bowl to the single digits above zero in the mountains around West Yellowstone. Winds are blowing 10-20 mph out of the WNW producing a very cold wind chill factor. With the cold air settling in, temperatures will work to reach 10 degrees above zero today and winds will stay out of the WNW at 10-15 mph. No new snow is expected over the next 24 hours.
Cooler temperatures have started to move into southwest Montana, but they have forgotten the snow. Currently, mountain temperatures are ranging from the mid teens to low 20s and winds are blowing out of the WSW at 10-20 mph. An approaching cold front will enter our area by early afternoon, dropping temperatures significantly through the later part of the day. Snow will likely arrive with this front, delivering 3-5 inches to the mountains by tomorrow morning. Temperatures will plummet well below zero tonight and will struggle to reach double digits above zero tomorrow.
The weather pattern is finally changing with some snowfall and cold air approaching. This morning temperatures were in the high teens to low 20s F and winds were blowing 15-30 mph from the W. Today temperatures will climb to the mid to high 20s F and winds will continue blowing 15-30 mph from the W. Places north of the advisory area will receive snow and much colder temperatures today. Snowfall in advisory area will arrive as moisture from the southwest meets cold air descending from the north. By tomorrow morning 2-3 inches of snow should fall in most places; however, exact amounts depend on the timing of this moisture and cold air which could meet late this evening or tomorrow morning.
This morning temperatures were in the high 20s F with winds blowing 10-30 mph from the W. Near Cooke City and West Yellowstone temperatures were in the high teens F with winds blowing 5-15 mph. Similar conditions will continue today with high temperatures in the low to mid 30s F while high temperatures near Cooke City and West Yellowstone will reach the low 20s F, and winds shouldn’t change much. A few snowflakes may fall tomorrow morning but no accumulations are expected. Colder air should begin arriving this evening and produce a cooling trend through the weekend.
A ridge of high pressure is the main weather feature today. This morning temperatures were in the mid 20s F and ridgetop winds were blowing 20-40 mph from the W. Near Cooke City and West Yellowstone, winds were calmer with temperatures around 11 degrees F. Today winds should blow 15-30 mph from the W and temperatures will warm into the low 30s F. Near Cooke City and West Yellowstone temperatures will warm into the low 20s F. No new snow is expected for the next couple of days.
As the snowstorm tapered off yesterday morning it dropped an additional two to three inches up Hyalite with a trace to one inch everywhere else. Temperatures reached the mid 20’s with westerly winds at 15-20 mph. A brief spell of “precipitation” (code word for rain) was reported on Mt Blackmore around noon yesterday. Today’s high pressure will bring partly cloudy skies, temperatures warming to the high 20s and westerly winds at 5-15 mph.
This is the thirteenth day in a row that we’ve gotten new snow in our advisory area. Last night all the ski areas picked up 3-4 inches with 2-3 inches falling everywhere else. Winds are blowing westerly at 10-20 mph with temperatures in the low 20s in the north to 10 degrees outside Cooke City. Scattered snowfall this morning will only drop another inch in the mountains. Under mostly cloudy skies winds will blow westerly at 15-25 mph as temperatures warm into the upper 20s.
