I’m not picky -- rain in the valleys and snow in the mountains is just fine. This morning at 6 a.m. there is nine inches of new snow up Hyalite and 6-7 inches everywhere else. All the mountain ranges got hit and it’s still snowing. Mountain temperatures are 15-20F, the coldest they’ve been in weeks. Winds are westerly at 15 mph with gusts of 30 mph at the ridgelines with Cooke City getting gusts of 40 mph. Today, temperatures will warm into the high 20s and winds will remain westerly averaging 15-20 mph. Snowfall will become sporadic and by tomorrow morning I expect an additional 4-6 inches in the mountains making it one of the biggest storms in the last two months…which is nothing to brag about, but enough to call in sick (cough, cough). Better charge the GoPro.

At 4 a.m. skies are partly cloudy and mountain temperatures range from the upper 20s to mid-30s F. Winds are blowing 15-25 mph out of the W-SW. Today, an approaching storm will produce mostly cloudy skies by late morning with an increased chance or valley rain and mountain snow this afternoon. There is a chance for an isolated thunderstorm associated with the frontal passage, which should arrive by mid to late afternoon. Winds will increase out of the west as the storm approaches producing gusts over 30 mph. Temperatures will warm into the upper 30s to low 40s F, but will drop sharply once the front passes. By tomorrow morning the mountains will likely receive 2-4 inches of new snow. A more potent storm system is forecasted to impact the area tomorrow into Wednesday.

Overnight a passing snow shower dropped one inch of snow in the mountains around Bozeman and two inches around Cooke City. This morning, temperatures are in the 20s F and winds are blowing 10-25 mph out of W-NW. Today, temps will warm into the mid to upper 30s F and winds will continue to blow 10-25 out W-NW. Skies will be mostly clear this morning but will become increasingly cloudy as the day progresses. Little to no precipitation is expected over the next 24 hours, but a good shot of valley rain and mountain snow is forecasted to impact the area tomorrow night into Tuesday.

This morning temperatures were in the mid to upper 30s F under clear but warm skies. Cooke City was the only place with mountain temperatures below freezing. Winds were blowing 10-25 mph from the SW. Today temperatures should again rise into the 40s F. Winds will increase some and blow 15-30 mph from the SW. Some clouds should arrive by afternoon and may deliver a trace of precipitation tonight.

This morning temperatures were only a few degrees below freezing. Skies were clear but warmer than yesterday morning and westerly ridgetop winds were blowing 15-30 mph. Today will have more sunshine and warm temperatures which should reach the mid-40s F. Winds should blow 10-25 mph generally from the W. A ridge of high pressure currently over the area should start to leave sometime Saturday and allow an unsettled weather pattern into next week.

Yesterday morning a little more precipitation fell in most areas as rain at elevations below 7000 ft and ½ to 1 inches of snow at elevations above 9000 ft (.1-.3 inches of SWE). In between I’m not sure if it rained or snowed. More importantly temperatures dropped and skies cleared overnight with temperatures this morning in the high teens to low 20s F. Winds this morning were blowing westerly at 10-20 mph. Today will have strong sunshine and rapidly rising temperatures which should reach the 40s F but feel much warmer. Winds should blow 5-15 mph from the WSW.

It snowed above 7,000 feet last night and rained below. At 6 a.m. the Big Sky area and Bridger Range picked up 5 to 6 inches of wet snow; Cooke City got 2-3 inches and 1-2 inches fell everywhere else. At 9,000 feet temperatures are in the upper 20’s with west winds blowing 15 mph and gusting to 25 mph. Precipitation will taper off this morning after dropping another inch or two, then skies will clear tonight with sunny and warm weather returning Thursday and Friday.

At 5 a.m. the mountains around Cooke City are showing five inches of dense snow, an inch around West Yellowstone and a trace everywhere else. Under cloudy skies winds are blowing out of the west to southwest at 10-15 mph with gusts of 20-30 mph.  The Bridger Range has east winds this morning, but will switch to southwest as the day progresses.  Mountain temperatures are in the mid to upper 20s. Precipitation will continue and by tomorrow morning the mountains could have 2-4 inches with closer to 6 inches in Cooke City, and additional snow falling on Wednesday. The freezing line will rise to 8-9,000 feet today, so be prepared for some drizzle when you step out of the car.

This morning mountain temperatures are in the upper 30s to mid-40s F and winds are blowing 15-30 mph out of the W-SW with stronger gusts being recorded in many mountain locations. Great Falls weather station at Big Sky recorded gusts up to 87 mph overnight.  Today, Skies will be partly to mostly cloudy and mountain temps will stay in the 40s F. Winds will continue to blow 15-30 mph out W-SW this morning, but will gradually decrease throughout the day. A weak weather disturbance will move over the area tonight and tomorrow producing valley rain and mountain snow. 1-3 inches of snow is possible above 7,000 ft. by tomorrow afternoon.

This morning mountain temperatures are in the upper 30s to mid-40s F and winds are blowing 15-30 mph out of the W-SW with gusts near 50 mph being recorded in many mountain locations. Today, Skies will become increasingly cloudy as a weak storm system approaches from the west. Mountain temps will warm into the mid to upper 40s and winds will continue to be strong out of the W-SW. There is a chance for rain and snow showers this afternoon and evening. Snow levels will be around 8,000 ft. where 1-2 inches might accumulate. Rain will be likely at lower elevations. Precipitation amounts for this storm appear to be light.
