Yesterday it snowed a lot, temperatures dropped, and winds were relatively calm. Since yesterday morning, the mountains near West Yellowstone received 27 inches of snow, near Cooke City 15 inches, near Big Sky and Bozeman 10 inches. There must have been a donut hole in the storm over the southern Madison Range and the Taylor Fork area which only received 3 inches of snow. This morning temperatures dropped into the low teens F and winds were blowing 10 mph from the W with gusts of 15 mph. Skies were clearing this morning and today will be a mix of sun and clouds. Temperatures will rise into the mid to high 20s F. Winds will blow from the W and SW and increase this afternoon blowing 10-15 mph with gusts of 25 mph.
Since yesterday morning the mountains near Cooke City received 8 inches of snow, the mountains near Bozeman 4-5 inches, and the mountains near Big Sky and West Yellowstone 2-4 inches. Snow is falling this morning and it should continue through today ending tonight. Temperatures this morning were in the high teens to low 20s F, and winds were blowing 5-15 mph from the N and E. Today, temperatures will remain the same or possibly drop a few degrees. As an area of low pressure moves E today, winds will increase to 15-30 mph and rotate around the northern half of the compass. By tomorrow morning 6-8 inches of snow should accumulate, but this spring storm will deliver atypical snowfall patterns, and I’m not sure which areas will get more and which will get less.
Temperatures dropped into the high teens last night with 1-2 inches of new snow falling early this morning. Yesterday, under partly cloudy skies, temperatures reached the upper 40s as west winds blew 15-25 mph. Last night as the cold front moved in, winds speeds reached 40-60 mph. Light snow will continue today and pick up intensity tonight through Friday. Winds will be westerly at 15-25 mph with mountain temperatures dipping into the low teens tonight. By tomorrow morning I expect this spring storm to deliver 4-6 inches of new snow.
Mountain temperatures reached the mid to high 40s yesterday under sunny skies. Winds have been west to southwest at 10-20 mph. Last night was clear, but not very cold. Bridger Bowl reads the mid-thirties this morning while other areas are in the high 20s to 31F; barely freezing. A cold front is headed our way from the Pacific coast. Today will start sunny, but later this morning high clouds will roll in as winds become stronger from the southwest. Mountain temperatures will rise into the high 40s and cool off significantly tonight. Tomorrow and Friday look to be cloudy, twenty degrees colder and snowy.
Yesterday was sunny, but mountain temperatures only reached into the mid-30s. Under clear skies this morning temperatures are in the high teens as winds blow 10-20 mph out of the southwest. Today will be sunny with temperatures reaching the 50s as winds remain light. Tonight looks to be clear and cold again with more sunshine on Wednesday. In the valleys I’m forecasting balmy temps in the 60s along with sightings of flip-flops, shorts and pasty white legs.
Over the past 24 hours 10-12 inches of snow fell in the northern Madison Range, 8 inches fell in the Bridger Range, 4-6 inches fell in the southern Madison Range and 1-2 inches fell in the mountains around West Yellowstone and Cooke City. Currently, temperatures are in the single digits on Lone Mountain and 10-20 degrees elsewhere. Winds are blowing 10-20 mph out of the WSW. Today, cool temperatures will persist with highs reaching into the upper 20s to low 30s. Winds will continue to blow 10-20 mph out of the WSW. A building ridge of high pressure will produce clear and calm conditions through the day. A warming trend will begin tomorrow and last through Wednesday.
Unbelievable! Last night a cold winter storm dropped over two feet of cold smoke powder in the mountains around Bozeman and Big Sky. The riding conditions should be some of the best of the year. April Fools! In fact a warm spring storm dropped nearly an inch of rain in the northern Gallatin Range. Most other areas picked up .2-.3 inches of rain. Currently, mountain temperatures are in the upper 20s to low 30s and winds are blowing 20-30 mph out of the WSW with gust reaching into the 40s. Today, temperatures will only warm a few degrees as a cold front moves over the region. Valley rain and mountain snow will be likely through the day. The southern mountains including Big Sky should pick up 3-5 inches of snow by this afternoon. The mountains near Bozeman will pick up 2-4 inches.
Since yesterday morning 4-6 inches of high density snow totaling 1.2 inches of SWE fell in the mountains around Cooke City. The Lionhead area and southern Madison Range picked up .7-.8 inches of SWE which fell as very dense snow or rain. The mountains around Bozeman and Big Sky picked up a trace to one inch of snow.
At 4 am this morning, mountain temperatures are in the mid to high 30s and winds are blowing out of the WSW at 20-40 mph. Today, skies will be partly to mostly cloudy, temperatures will warm into the 40s and winds will continue to blow 15-30 mph out of the WSW. Another storm will move into southwest Montana by tomorrow morning. Valley rain and mountain snow can be expected through the day tomorrow.
Since yesterday the mountains near West Yellowstone and Cooke City received 4 inches of snow, the Taylor Fork area received 2 inches, Hyalite received 1 inch, and all other areas were mostly dry. Yesterday all areas remained below freezing except the Bridger Range which didn’t get too warm with a high temperature of 38 degrees F. This morning temperatures in the Bridger Range were hovering near freezing while other areas had temperatures in the high 20s F. Winds were blowing 10-20 mph from the W and SW with gusts of 40 mph.
Today will be mostly cloudy and temperatures will rise into the upper 30s F (40s F for the Bridger Range. The mountains near Cooke City and West Yellowstone will get 6 inches of snow. Mountains near Big Sky will get 2-3 inches and maybe only an inch near Bozeman. Spring storms can be surprising, and I have little confidence in these snowfall amounts. A lot more or a lot less could easily accumulate.
Overnight 1-2 inches of snow fell and temperatures dropped into the high teens to low 20’s F. This morning winds were blowing 5-10 mph from the SW with gusts of 20 mph. Today’s weather will bring a mix of clouds and sun with some precipitation this afternoon and tonight. By afternoon winds will increase and blow 15-20 mph from the SW with gusts of 40 mph. Temperatures will climb into the high 30’s and low 40’s F. Another inch of snow should accumulate by tomorrow morning.
