A dry and mild weather pattern will persist over southwest Montana through the holiday weekend. Santa will likely have smooth sailing while making his rounds tonight into tomorrow. Currently – mountain temperatures are in the mid teens to low 20s and winds are blowing predominately out of the west at 15-30 mph. Today, temperatures will rise into the mid to high 20s under partly cloudy skies and winds continue to blow 15-30 mph out of the WNW.
Yesterday was beautiful and clear but winds increased in the afternoon. This morning on ridgetops at Bridger Bowl and Hyalite Canyon winds were blowing 25-30 mph with gusts 40-50 mph from the W and NW. In other areas winds were blowing 15 mph gusting to 30 mph. Temperatures this morning were in the teens F and will climb into the 20s F today. Winds will remain strong generally blowing 15-30 from the NW; however, some downslope winds will occur today. It looks like the boys and girls of SW Montana have been bad this year and will not get any snow for Christmas. Instead of coal in our stockings, it looks like we’ll get a good dose of wind.
Since yesterday morning an additional 6-10 inches of snow fell in the Gallatin and Madison Ranges while the Bridger Range and Cooke City got an inch at most. Temperatures this morning were in single digits F and northerly winds calmed to 5-10 mph with some gusts of 15 mph. During the storm yesterday winds blew stronger at 15-30 mph sometimes from the E. Skies began clearing overnight and today will be mostly sunny with temperatures rising into the low teens F. Winds will remain northerly at 5-10 mph with some gust up to 20 mph.
It started snowing in the mountains around midnight which will continue today. At 6 a.m. the Gallatin and Madison Ranges (Bozeman to West Yellowstone) are showing 5-6 inches of light powder with Cooke City getting 2-3 inches and the Bridger Range 1-2 inches. Mountain temperatures are in the teens with northwest winds averaging 10-15 mph and gusts into the 20s. Snowfall will end later today with an additional six inches falling at the higher elevations.
Mountain temperatures are in the high teens this morning with west to north winds at 15-30 mph and gusts hitting 40 mph. Today will start sunny, but clouds will increase later this afternoon as a cold front brings snowfall late tonight. Steady 20-40 mph winds will blow ahead of the front with nighttime temperatures dropping into the low teens. By morning I’m expecting 3-4 inches of snow with storm totals of 6-8 inches by Wed night.
Over the past 12 hours a fast moving cold front has swept down from the north, depositing 2-3 inches of snow in the mountains around Bozeman and Big Sky. The southern ranges only picked up a trace. Winds spiked during the frontal passage, but have decreased to 5-15 mph out of the NNW. Mountain temperatures are currently in the high teens to low 20s F. Snow showers will taper off this morning and skies will become partly cloudy by this afternoon. Today, mountain temperatures will rise into the high 20s and winds will blow out of NNW at 10-20 mph.
Yesterday was a warm day with mountain temperatures reaching above freezing. Under a slight inversion, temperatures at 5 a.m. are in the high 20s as westerly winds blow 20-30 mph in the north and 10-20 mph in the southern mountains. A cold front drops in later this afternoon which will bring a small, but welcome shot of snow. I’m expecting 1-2 inches tonight as temperatures drop into the teens with west to northwest winds blowing 15-25 mph.
This morning temperatures were near 20 degrees F except near Cooke City and West Yellowstone where temperatures were near 10 degrees F. Winds this morning varied across the region blowing from all directions on the western half of the compass. At ridgetops near Bridger and Hyalite Canyon winds were blowing 20-40 mph, near Big Sky 5-15 mph, and further south near West Yellowstone and Cooke City 5-10 mph. No snow fell overnight and none is expected today which will have mostly sunny skies and temperatures approaching 32 degrees F. Westerly winds will blow 10-20 mph.

Yesterday an additional 1-2 inches of snow fell. Not much, but a little snow is better than none at all. This morning winds were blowing 15-20 mph from the SW with temperatures in the low teens F. Today will be mostly cloudy and temperatures will be in the high teens F. Winds will increase and blow 15-30 mph from the W. Late this afternoon some moisture should arrive from the north but only produce 1-2 inches of snow. Long range models indicate more snow for the rest of December. Keep your fingers crossed.
