Yesterday the mountains near Cooke City received 5 inches of snow and the mountains south of West Yellowstone received 3 inches while all other areas received a trace. This morning temperatures were in the low 20s F and winds were blowing 10-15 mph from the W and SW with gusts of 25 mph. Today temperatures will rise into the low 30s F. Wind speeds will remain the same but wind directions should shift more to the S and SW. Clouds will build late this afternoon and tonight a little more snow should fall. Mountains near Bozeman and Big Sky may get an inch of snow with more possible further south.

This morning mountain temperatures were in the high 20s and low 30s F. Winds increased yesterday afternoon. This morning they were averaging 20 mph with gusts of 30-40 mph from the SW. No snow fell overnight but a little snow was just starting to fall this morning. Don’t get too excited because only an inch or two will accumulate today. Temperatures will drop a little by afternoon and winds will blow 15 mph gusting to 30 mph from the W.

Under partly cloudy skies there’s no new snow to report. Mountain temperatures are in the low thirties around Bozeman and Big Sky and mid-twenties near Cooke City and West Yellowstone. Currently, west to southwest winds are blowing 10-25 mph at the ridgetops. Clouds will increase later today with some flurries expected after midnight as winds increase to 30 mph and mountain temperatures cool into the twenties. By morning we’ll see a trace to one inch of snow, if we’re lucky.

A ridge of high pressure is firmly parked over the western US. At 4 a.m. temperatures are in the low 20s under clear skies. Today will be a repeat of yesterday, but slightly warmer: sunny skies, westerly winds 15-30 mph and mountain temperatures reaching the upper-thirties. Sunburns are a greater threat today than avalanches.

At 4 a.m. mountain temperatures are in the 20s F and winds are blowing 15-25 from the WNW.   Today, temperatures will warm into the low 30s F under partly to mostly cloudy skies and winds will continue to blow 15-25 from the WNW.  There is no chance for precipitation over the next 24 hours.  

A ridge of high pressure off the pacific coast is producing a northwest flow over our area.  Unfortunately, there is little moisture associated with this flow meaning southwest Montana will remain dry today.  Currently, temperatures are in the high teens to low twenties F and winds are blowing 15-25 out of WNW.  Today, temperatures will climb into the upper twenties F to low thirties under partly cloudy skies and winds will remain 15-25 out of the WNW.  No snow is expected over the next 24 hours.

Yesterday winds were gusting 40-60 mph but eased some this morning blowing westerly 10-30 mph.  A slight inversion was in place this morning with mountain temperatures near 20 degrees F and valley temperatures in the teens F and just below zero F near West Yellowstone.  A NW flow at the leading edge of a ridge of high pressure may bring a few clouds over SW Montana today.  Temperatures will climb into the high 20s and low 30s F, and westerly winds will blow 10-30 mph.

A ridge of high pressure over the Pacific Northwest is responsible for warm, sunny and windy conditions over SW Montana. This morning mountain temperatures were in the mid 20s F with valley temperatures in the mid teens F.  Westerly winds were averaging 15-30 mph with gusts reaching 40-50 mph.  Winds will remain strong today and temperatures should approach 32 degrees F, but some places like the Bridger Range could see temperatures in the 40s F.

Yesterday was warm and sunny with more of the same forecasted today.  This morning mountain temperatures were near 20 degrees F and winds were blowing from the SW to NW 5-15 mph gusting 25-30 mph.  With more sunshine today, temperatures will be in the low 30’s F.  Winds will remain westerly and wind speeds shouldn’t change much.

Early yesterday morning another inch fell around Big Sky before clouds lifted and high pressure moved in. Temperatures this morning are in the teens up north and single digits in the southern ranges. West to northwest winds have been blowing 35-50 mph in the Bridger Range and up Hyalite Canyon, but are 15-30 mph elsewhere. Today will be mostly sunny with mountain temperatures reaching the low twenties as westerly winds weaken to 15-25 mph. No new snow is expected for the next several days.
