Yesterday, the groundhog saw his shadow, which means six more weeks of winter. Hopefully an active and snowy weather pattern continues during this time. Over the past 24 hours, the mountains around Cooke City picked up 3-5” of low density snow while the mountains around Big Sky and West Yellowstone picked up 1-2”. This morning, mountain temps are in the single digits to low teens F under partly to mostly cloudy skies. Winds are blowing 15-25 mph out of the W-SW with ridgetop gusts in Hyalite and Big Sky hitting close to 40 mph. Today, temps will warm into the teens to low 20s and winds will steadily increase out of the W-SW. A storm system will move into the area this evening producing light to moderate snowfall in the southern mountains. Cooke City, West Yellowstone and Big Sky will see 4-6” by tomorrow morning while the mountains around Bozeman will see 1-3”. 

Over the past 24 hours no new snow has fallen. At 5 a.m. temperatures are in the single digits above or below zero F under mostly cloudy skies. Winds are blowing 5-15 mph out of the E-SE.
