Overnight the mountains picked up a trace of new snow. This morning temperatures are ranging from the single digits above or below zero F and winds are light out of the WNW blowing 5-10 mph. Today, a cold northwest flow will allow highs to warm into the upper teens to low 20s F and winds will stay light out the WNW. Skies will stay partly to mostly cloudy with both sun and light snow showers likely throughout the day. A ridge of high pressure will build this evening producing clear skies and warmer temperatures tomorrow.

Overnight three inches of low density snow fell in the Bridger Range.  A trace to one inch fell elsewhere. At 4 a.m. temperatures are in the single digits above or below zero F and winds are blowing 5-10 mph out of the WNW. Today, temperatures will stay well below average with highs warming into the teens F and winds will stay light out of the WNW blowing 5-10 mph. Skies will start out partly to mostly cloudy this morning, but will become obscured by this afternoon as another round of moisture arrives from the north. 1-3 inches is possible by tomorrow morning in the mountains around Bozeman and Big Sky. The southern mountains will see a trace on one inch.

Since yesterday morning, Hyalite Canyon received 4 inches of new snow. Most other places received 1-2 inches while the mountains near West Yellowstone got a trace at best. Temperatures this morning dropped into the single digits F and winds were blowing 10 mph gusting to 15 mph from the W. Yesterday winds blew 20 mph gusting to 40 mph from the W.

Weather for the next few days should be perfect for preserving snow quality: cold temperatures, light winds, and not too much strong sunshine. Today temperatures will struggle to reach the teens F and winds will shift to the N and blow 5-10 mph. About an inch of snow should fall this afternoon.

Snow fell yesterday and early this morning. In most places snowfall was ending this morning with 24 hour totals of 4 inches in the Bridger and Northern Gallatin Ranges and 6-8 inches everywhere else. Winds were blowing 15-20 mph and gusting to 35-50 from the SW. As temperatures began dropping into the teens F, winds eased and shifted to the W. Today will be cold with temperatures reaching the low teens F. Mostly cloudy skies will produce snow with 1-3 inches by tomorrow morning. Winds will blow from the W at 10-15 mph with gusts of 25.

Another inch of snow fell in the southern mountains before the skies cleared yesterday morning. By afternoon temperatures rose into the mid-20s, westerly winds decreased and sunny skies prevailed. Mountain temperatures are still near 20F with winds averaging 15-25 mph out of the southwest. Today will start cloudy, get sunny later this morning, then cloud over again.  Mountain temperatures are expected to climb above freezing. Tonight a moist disturbance from the southwest will drop freezing levels and bring snow, favoring the southern mountains. By morning there should be 3-6 inches.

Last night four inches of new snow fell in the northern Gallatin Range with 1-2 inches covering the rest of our area. Winds are averaging 20-25 mph out of the west with gusts hitting 50 mph.  This morning mountain temperatures are near 10F, but will warm into the upper 20s by this afternoon. Today will be dry and sunny with winds tapering off. There’s no snow expected in the next 24 hours, but we are poised to get moisture later tomorrow. Moisture is code for “it might be rain”.

Yesterday’s storm totals averaged 4-6 inches in most mountain locations. The Bridger Range was the big winner with a total of 9 new inches.  This morning, clear skies have allowed temperatures to drop into the single digits F and winds are blowing 10-20 mph out of the WNW.  Today, highs will climb into the upper teens to mid-twenties F under partly to mostly cloudy skies and winds will continue to blow 10-20 from the WNW.  A light weather disturbance will move over the area this afternoon producing a chance for mountain snow showers. 1-2 inches is possible by tomorrow morning.

Overnight 3-5 inches of snow fell in most mountain locations. Currently, it’s still snowing and temperatures are in the upper teens to low twenties F. Winds are blowing 15-30 mph out of the west with ridgetop gusts reaching close to 40 mph.  Today, temperatures will continue to drop as a cold front moves over the area.  By noon, temperatures will be ten degrees colder and winds will continue to blow 15-30 mph out of the west/northwest. Snow will continue through the day with an additional 2-4 inches likely by this evening.  With new precipitation, a rainbow may appear today but don't expect to find a fat pot of gold at its base – we’re still be dealing with dust on crust conditions.

This morning ridgetop temperatures were in the low 20s F. Lower elevations had temperatures in the high 20s F. Winds were blowing westerly at 10-15 mph in most areas. Today will be cooler than yesterday, and temperatures will be in the high 20s F to low 30s F with some sunshine and clouds. Winds will continue at 10-15 mph generally from the W. There is a chance for snow today and a better chance tonight. By tomorrow morning, 1-3 inches will accumulate in most areas. Snowfall will continue tomorrow.

This morning mountain temperatures were near freezing at ridgetops and near 40 degrees F at lower elevations. Winds were blowing 15-20 mph from the WSW and gusting to 35 mph. Today’s exact temperatures will be a factor of cold air pushing south at 10K feet, warm air in places at 5K feet, and a mix of sun and clouds. Overall high temperatures will be in the 40s F. There will be a small chance for some snow or rain. Fortunately cold air will arrive tomorrow followed by snow and even colder air on Sunday.
