Over the past 24 hours 2-3 inches of snow fell in the mountains around West Yellowstone and Cooke City.  A trace to one inch fell in the mountains around Bozeman and Big Sky.  These numbers will increase today as moisture arrives on a southwest flow. By this evening, an additional 3-5 inches will accumulate in the southern mountains and 2-4 inches will fall in the north.

This morning temperatures are in the 20s F and winds are blowing 5-15 mph from the WSW.  Today, temperatures will climb into the upper 20s to low 30s under snowy skies and winds will continue to blow 10-20 from the WSW.  Snow will taper off this evening and temperatures will drop to around 10 degrees F.  Another potent storm is scheduled to arrive Monday night into Tuesday.

Overnight 1-2 inches of snow fell in the mountains around Bozeman, Big Sky and Cooke City.  The southern Madison Range and mountains around West Yellowstone picked up 2-3 inches.  Morning temperatures are in the mid to upper 20s F and winds are blowing 15-25 from the WSW with gusts reaching upward of 30 mph. Today, light snow is likely in the mountains with an additional 1-2 inches possible by this afternoon.  Mountain temperatures will warm into the upper 20s to low 30s F and winds will continue to blow 15-25 from the WSW.  A stronger storm system will impact our area starting tonight and should deliver 3-5 inches by tomorrow afternoon.

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.
