Since yesterday the mountains around Bozeman received 6 inches of cold smoke. The mountains near Big Sky and Cooke City received 4 inches, and the mountains near West Yellowstone received 2 inches. Temperatures this morning were near 0 F, a little below at ridgetops and a little above in valleys. Winds were blowing 10-15 mph gusting to 20 mph from the WNW with a few places seeing winds from the SW. Today temperatures will struggle to reach 10 F as cloudy skies slowly give way to a little sunshine. Fortunately winds should remain light and blow 5-10 mph mostly from the WNW with gusts of 15 mph. The next round of snow should come Monday following a decisive win by the Broncos Sunday night.
If you didn’t develop a case of powder flu yesterday, then consider calling in sick to work today.

This morning temperatures were in the high teens and low 20s F, and winds in most places had shifted to the NW and eased a little. As a cold front descends from the north today, temperatures should drop and winds should calm even more. The cold air and calm winds had already reached the Bridger Range at 5 a.m. Today another 3-4 inches of snow should fall. Temperatures should drop to near 10 degrees F with winds blowing 5-10 mph gusting to 20 mph from the NW.
Knock, knock…a storm is approaching. Under cloudy skies a trace to one inch of snow has fallen in many mountain locations. The next 24 hours will be snowy and breezy. Currently mountain temperatures range from 10F in the southern areas to 20F in the north. Wind speeds are averaging 20-25 mph with gusts of 40 from the west to southwest . A moist Pacific storm is approaching from the west bringing slightly colder temperatures, steady westerly winds and much needed snowfall. By tomorrow morning I expect 8-12 inches and maybe a little more in our southern areas. Just to be safe, you might want to develop an illness today so you can call in sick tomorrow. Just saying…
