The Bridger Bowl Cloud was in full force yesterday and dropped a total of 26 inches! Put the kids in daycare, call in sick, skip school and shred. This is why we live here, right? All other mountain ranges picked up 2-4 inches yesterday. Winds are still blowing at 20-30 mph, but the direction has switched from west to southwest. This morning is clear with mountain temperatures in the single digits, but this afternoon temperatures will rise into the 20s under partly cloudy skies.

I did a double take when I looked at my thermometer in Bozeman this morning. It read 18 degrees, thirty degrees warmer than a couple days ago--almost t-shirt weather! Mountain temperatures are still chilly with minus 5-10F around West Yellowstone and Cooke City; 5-10F elsewhere. At 6 a.m. it’s snowing in the mountains with 2-4 inches falling so far. Winds picked up yesterday and are currently blowing westerly at 20-30 mph and gusting into the 40s. Snowfall will end this afternoon and winds will taper off tonight. Another 3-6 inches will fall, but I expect double that in the Bridger Range given the favorable moist, northwest flow.

Over the past 24 hours a trace of new snow fell over most mountain locations. At 4 a.m. temperatures remain frigid. The mercury is reading -20 F in the mountains around Cooke City and West Yellowstone and -10 to -15 F elsewhere. To make matters worse, westerly winds are blowing 15-25 mph with gusts in the 30s. Although temperatures will actually warm above zero today, strong winds will continue to make it dangerously cold. Skies will be partly to mostly cloudy and there is a slight chance of mountain snow showers later this afternoon. The good is – temperatures will gradually warm throughout the week. Tomorrow looks to be a much warmer day with a good possibility of snow. The mountains could pick up 4-6 inches by Wednesday morning.
