Since yesterday morning a trace to one inch of snow fell in the mountains around Big Sky and West Yellowstone; all other areas remained dry.  Currently, temperatures are ranging from the single digits to low teens and winds are blowing 5-15 mph out of the ENE.  Today, temperatures will warm into the 20s F under partly to mostly cloudy skies and winds will blow 5-15 from the NNE.  A Canadian cold front with a limited amount of moisture will impact our area tonight into tomorrow.  The mountains around Bozeman, Big Sky and Cooke City will likely see 2-4 inches of snow by tomorrow afternoon.  The mountains around West Yellowstone will pick up 1-3 inches. 

Under partly cloudy skies and very light winds, mountain temperatures are in the upper teens this morning.  For the next 24 hours winds will remain 5-15 mph out of the southwest with temperatures reaching the mid-20s under increasing cloud cover. A few flurries may dust the southern ranges, but no accumulation is expected. Tomorrow the weather pattern will change in favor of snow, so do not despair. 

Under clear skies this morning, mountain temperatures were in the mid-teens F and SW winds were blowing 10-15 mph gusting to 25 mph. Today an upper level ridge will move east and some clouds will move over the area. Temperatures should climb only a few degrees to near 20 F and winds will continue the same.  Some snow will come Friday followed by cold temperatures on Sunday.

At 5 a.m. there’s no new snow to report. Westerly winds are averaging 10-15 mph with gusts to 30 mph under clearing skies.  Mountain temperatures are near 20F. Today will be partly cloudy as winds remain the same and temperatures rise into the high 20s. High pressure is building and there will be little chance of precipitation over the next few days.

This morning mountain temperatures were near 20 degrees F.  Westerly winds were blowing 20 gusting to 40 mph in the Bridger Range and northern Gallatin Range.  In all other areas westerly winds were blowing 10 gusting to 20 mph.  Since yesterday, Hyalite Canyon and the mountains near Cooke City received about an inch of snow.  A few other places received a trace.  Cloudy skies this morning may produce another dusting and maybe an inch in places.  Without much sunshine today, temperatures shouldn’t warm too much.  Winds may increase a little and back to the SW.

This morning mountain temperatures are in the mid-teens to low twenties F and westerly winds are blowing 5-20 mph with ridgetop gusts reaching close to 50 mph in Hyalite.  Today, temperatures will warm into the mid-twenties to low thirties F and winds will continue to blow 10-20 mph out of the west. Ridgetop gusts will remain strong in the mountains around Bozeman and Big Sky blowing 30-40 mph.  An unsettled northwest flow aloft will produce light flurries in the mountains of southwest Montana; however, accumulations will stay less than an inch. 

For the first time in nearly a week there is no new snow to report.  Today will be a near ground hog day to yesterday with plenty of sunshine and warm temperatures.  This morning, temps are in the high teens to mid-twenties F and winds are averaging 5-15 mph out of the WSW with gusts reaching close to 30 mph. Today, highs will climb into the 30s F under clear skies and winds will remain out of the WSW blowing 5-20 mph.  No new snow is expected over the next 24 hours.

Snow showers yesterday morning produced 2-4 inches in most areas.  This morning temperatures were in the teens F and westerly winds were blowing 10-15 mph with gusts 20-30 mph.  Today will be mostly sunny with temperatures in the low 30s F.  Westerly winds will blow 10-25 mph.

This morning temperatures were in the high teens and low 20s F with winds blowing 10-15 mph from the west and gusting 20-30 mph. Today temperatures may drop a few degrees and winds will ease just a little shifting to the WNW.  Snowfall will end around midday with 1-3 inches accumulating in most areas. By late afternoon a few rays of sunshine may break through the clouds making way for more sunshine this weekend.

Since yesterday morning 15 inches of snow fell in Hyalite Canyon, 10-12 inches near Bridger Bowl, 8-9 inches near Big Sky and Cooke City, and 2-6 inches near West Yellowstone.
