Who would’ve thought it snowed 16 inches last night?! Well, no one. It’s April Fools. But five inches at Bridger Bowl and Big Sky? Now that’s real. Everywhere else got two to three inches of new snow except West Yellowstone which got missed.

It started snowing at midnight as temperatures dropped into the upper teens and winds spiked to 60 mph out of the west. Speeds have calmed substantially and are now averaging 10-20mph with gusts of 35. Today will become partly cloudy with scattered snow showers dropping another inch by morning. Mountain temperatures will remain cool and only reach the low 30s as winds remain westerly at 10-25 mph.

It did not freeze in the mountains last night and temperatures are in the upper 30s to low 40s. Skies are partly cloudy with ridgetop winds from the southwest averaging 10-15 mph with gusts to 25 mph. Today will be warm and mostly sunny with temperatures getting to 50F before a cold front arrives this evening. Ahead of the front, winds will increase and rain will fall before tuning to snow with temperatures dropping into the high teens. By morning I expect 2-3 inches of snow.

At 4 a.m. mountain temperatures are in the upper 20s to low 30s F and winds are blowing 10-20 mph out the west. Today, a building ridge of high pressure will produce mostly sunny skies and warm temps. Highs today will warm into the upper 40s to low 50s F and winds will remain light to moderate out of the west. High pressure will dominate the weather pattern over the next 24 hours, but a storm system is forecasted to impact the area Tuesday night into Wednesday bringing valley rain and mountain snow.

The storm system that blew through yesterday created some wild conditions. Wind gusts up to 70 mph were recorded in many locations. Precipitation was light, but most areas picked up a trace to one inch of snow with Carrot Basin in the southern Madison Range picking up 2-3 inches. Conditions have calmed significantly this morning and winds are blowing 10-20 mph out W-SW. Temperatures are in upper teens to low 20s F under clear skies. Today, a building ridge of high pressure will produce mostly sunny skies and warm temperatures. Highs today will climb into the 60s in the valley and 40s F in mountains. Winds will remain light to moderate out of the W-SW. High pressure will dominate the weather pattern over the next few days.

This morning temperatures range from the mid-30s to low 40s F under mostly clear skies. Winds are blowing 15-30 mph out of the W-SW. Today, a weak weather disturbance will push into the region producing gusty winds and mostly cloudy skies. There is a slight chance for a mountain rain shower this afternoon. Temperatures will warm into the mid to upper 40s F today, but will drop as the storm system moves over the area. Winds will increase out of the W-SW throughout the day with gusts upwards of 40 mph possible with the frontal passage.

Yesterday morning the mountains near Bozeman received a trace of precipitation, rain or snow depending on elevation. Temperatures this morning were a few degrees either side of freezing under clear but warm skies. Near Bozeman gusty winds were blowing 20-35 mph from the W and 10-25 mph from the W in all other areas. Today will be mostly sunny and mountain temperatures could reach 50 degrees F in some places. Winds will blow 10-20 mph from the W.

Since yesterday morning 1-2 inches of snow fell near Bozeman and Big Sky where temperatures were in the mid 20s F with westerly winds blowing 15-30 mph. Further south this morning, temperatures were a few degrees cooler and westerly winds were blowing 10-20 mph. Today will have clouds and some sunshine this afternoon. Temperatures will warm into hi 30s to low 40s F and winds will blow 10-20 from the W. A ridge of high pressure will move over the area tomorrow bringing warm temperatures and more sunshine.

Since yesterday morning the mountains got hit with another round of snowfall: 4” in the Bridger Range; 6” up Hyalite; 10” at the Yellowstone Club; 4” in Taylor’s Fork and 2-3” around West Yellowstone and Cooke City. This morning mountain temperatures are in the high teens with winds blowing out of the west at 10-20 mph. Snowfall will taper off in the next few hours and the day will clear before more clouds roll in bringing just a few flurries tonight. High pressure will build over the next couple days with record high temperatures forecasted on Friday.

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.
