Like the Packers running over the Steelers – potent weather events have marched right into southwest Montana, arriving on a strong NW flow. Since yesterday morning, the Bridger Range, northern Gallatin Range and mountains around Cooke City have received 10-12 inches of new snow. The mountains around Big Sky have picked up 5-6 inches, while the mountains around West Yellowstone have picked up 2-3 inches. Winds are currently blowing out of the WNW at 15-20 mph and will continue along these lines for the remainder of the day. Mountain temperatures are ranging from the single digits to low teens and will gradually climb into the mid 20s by this afternoon. Snow will taper off by this morning, but another round of moisture will move back into our region by early tomorrow. Another foot of snow is possible in the northern mountains by tomorrow evening.
A moist NW flow has delivered a welcomed shot of snow to southwest Montana. Since yesterday morning, 11 inches of snow has fallen in the mountains around Cooke City; 5-6 inches has fallen in the mountains around Bozeman and Big Sky and 3-4 inches has fallen around West Yellowstone. Winds are blowing out of the W-NW at 20-30 mph with ridgetop gusts reaching into the 40s. Temperatures are in the high teens to low 20s and will warm into the mid 30s by this afternoon. Snow will continue through the day with an additional 3-6 inches possible by this evening. Southwest Montana will see a break in the weather tonight, but another round of snow will impact our region Sunday night into Monday.
After cold weather early this week, this morning feels like a heat wave with temperatures in the mid to high 20s F except near West Yellowstone where temperatures were in the low teens F. Winds this morning were blowing 20-35 mph from the W and NW. Most places received an inch of snow overnight and more should return later today. High temperatures should be near 30 degrees F (low 20s for West Yellowstone) and strong winds will continue blowing 20-40 mph from the W and NW. 3-4 inches of snow should accumulate by tomorrow morning. Sunday evening I’m expecting more snow and a big win by the Steelers.
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.
