The final round of snow dropped 6-8 inches in the Bridger and northern Gallatin Ranges. Cooke City picked up 5 inches and 1-2 inches fell everywhere else. Winds blew out of the west to northwest at 25-50 mph yesterday morning before dramatically shifting to the east mid-afternoon. Following this wind shift, mountain temperatures dropped almost 20 degrees in three hours, bottoming out at minus two, while winds lessened and snowfall stopped. Winds are currently blowing 20-30 mph out of the ESE in the Bridger Range with other mountains having light, easterly, 10 mph winds. Today will be partly cloudy with mountain temperatures reaching the high single digits with no snowfall expected.
A strong NW flow has delivered yet another round of moisture to southwest Montana. Since midnight, 3-4 inches of new snow has fallen in the mountains around Big Sky and Bozeman, all other locations have picked up 2-3 inches. Winds have been ramping up with the arrival of this storm blowing out of the WNW at 20-30 mph with gust reaching into the 40s. Mountain temperatures are currently in the teens and will warm into the low 20s by this afternoon. Snow and wind will continue throughout the day with an additional 6-8 inches falling the north and 3-6 inches accumulating in the south.
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.
