Last night’s cold and clear skies made good flying conditions for Santa. I could barely sleep, all excited about what he was bringing me. But when I looked outside for my new truck, I just saw my dented old one. I was dissed by Santa again. But at least I’ve got a nice day ahead of me: fresh snow from the weekend, southwest winds blowing 15 to 30 mph (NW direction in Cooke City), and temperatures in the teens that will reach into the high twenties this afternoon under mostly sunny skies. Overall, high pressure dominates with no snowfall predicted in the next few days.
Snowfall continued through last night with 24 hour totals of 4-6 inches in the mountains around Bozeman, Big Sky and West Yellowstone. Cooke City received over a foot. Winds increased yesterday out of the west to southwest at 20-40 mph, but spiked last night with gusts near 60 mph. Cooke City still has strong northwest winds blowing 30-50 mph. Today will become partly cloudy and temperatures will rise into the upper twenties by this afternoon. No new snow is expected and Santa should have good visibility as he makes his rounds to all those naughty and nice.
Over the past 24 hours the mountains around Bozeman and Big Sky as well as Cooke City picked up 4-6 inches of new snow. The southern Madison Range and Lionhead area near West Yellowstone picked up 2-4 inches.
This morning, temperatures are 10 degrees F around Cooke City and West Yellowstone and the mid to high teens elsewhere. Skies are partly to mostly cloudy and winds are blowing 10-20 mph out of the west-northwest. Today will be the warmest day of the week with highs climbing into the upper 20’s to mid-30’s F. Winds will gradually increase through the day as the next storm system approaches from the northwest. There is a slight chance of mountain snow showers this afternoon with an increasing chance for snow tonight and tomorrow. The mountains around Bozeman and Big Sky will receive 2-4 inches by tomorrow. The southern mountains will likely pick up 4-6 inches.
If fresh powder is at the top of your wish list you’re in luck. Since midnight, the northern mountains have received 5-7 inches of new snow while the mountain around West Yellowstone and Cooke City picked up 2-4 inches. This latest round of moisture has been delivered on a northwest flow, which will likely persist through much of the day. By this afternoon, an additional 2-3 inches is possible in the mountains around Bozeman and Big Sky. The southern mountains should see an additional 1-2 inches.
This morning, temperatures are ranging between 10-15 degrees F and winds are blowing 10-20 mph out of the west with higher gusts being recorded around Big Sky. Today, temperatures will warm into the high teens to low twenties F and winds will continue to blow 10-20 mph out of the west. A northwest flow aloft will keep conditions unsettled for the next few days. Monday night into Tuesday looks to be the best chance for more accumulating snowfall.
