This morning is when we all found out if we’ve been naughty or nice, as if we didn’t already know. Santa is a judgmental soul but still brought most of us gifts of snowfall: 5 to 6 inches in the northern Gallatin and Madison Ranges, 3 to 4 inches in the southern mountains and just a trace, the equivalent of a lump of coal, to the Bridger Range. Winds spiked yesterday afternoon to 30 mph for a couple hours, but otherwise have been light at 10-15 mph out of the west. Mountain temperatures are in the single digits and will only rise into the teens today under clearing skies. No new snow is expected in the next 24 hours. 

Over the past 24 hours the mountains around West Yellowstone and Cooke City picked up 2-3 inches of snow.  The southern Madison Range and mountains around Big Sky including the northern Gallatin Range picked up 1-2 inches.  The Bridger Range has remained dry.  Today, the southern ranges will see an additional 3-5 inches while the north will pick up 2-4 inches.  Currently, temperatures are in the teens F and winds are blowing 10-20 out of SSW.  Today, highs will reach into the 20s F and winds will remain out of the WSW at 10-20 mph.  Snow will taper off this evening as the storm pushes east.  Very little snow is expected tonight and Christmas Day looks to be dry.

Overnight a fast moving weather disturbance dropped 2-3 inches of snow in the mountains around West Yellowstone and Cooke City including the southern Madison Range. The mountains around Bozeman and Big Sky picked up a trace to one inch. Currently, temperatures are in the teens F and winds are blowing 10-20 out of the SSW with gusts reaching close to 30 mph. Today, highs will climb into the 20s F under partly to mostly cloudy skies. Winds will continue to blow 10-20 from the SSW. A more potent storm will impact our area tonight and tomorrow. 1-3 inches is possible by morning with 4-6 inches likely by tomorrow afternoon.

This morning temperatures were in the single digits F and ridgetop winds were blowing 15-20 mph from the W and SW with gusts of 30 mph. Major low pressure systems are impacting the west coast and the Midwest, but southwest Montana remains under a ridge of high pressure. Fortunately this ridge will flatten and move east this weekend. Today temperatures will climb into the teens F, and winds will increase and blow 25-40 mph from the SW.
