Since yesterday 5-8 inches of snow (0.8-1.0 inches of SWE) fell in the southern Madison Range and in the mountains near West Yellowstone and Cooke City. 3-5 inches fell in the Bridger Range and mountains near Big Sky (0.3-0.5 inches of SWE), and the Hyalite Canyon area received 1 inch. This morning winds were averaging about 20 mph from the SW gusting to 35 mph. Temperatures were near 32 degrees F.
Today will be warm and windy again. Temperatures in the mountains near Bozeman will be in the 40s F while other areas will have temperatures in the 30s F. Winds will continue from the SW blowing 20-30 mph and increase by this afternoon with gusts of 50 mph. The mountains near West Yellowstone and Cooke City should receive another 2-4 inches while other areas will get a dusting of snow or a sprinkle of rain.
Yesterday was windy at all elevations with southwest winds hitting 93 mph on Lone Mountain. Winds died down last night before the snowfall started. As of 6 a.m. the Bridger Range and mountains around Big Sky have six inches of snow while the southern Madison Range and mountains around West Yellowstone and Cooke City got 2-3 inches. Temperatures dropped into the mid-20s last night and winds are now WSW at 20-40 mph. Today, temperature and winds will not change much. A moist southwest flow will bring mostly cloudy skies and sporadic snowfall through tonight. By morning I expect 2-4 inches.
Warm and windy describe this morning’s weather. Mountain temperatures are near 30F under partly cloudy skies as west to southwest winds average 25-30 mph and gusts to 70 mph at the Yellowstone Club. Clouds will increase as a cold front moves in from the southwest. Winds will get even stronger as the front passes later today. Temperatures will drop into the low 20s and by morning the southern mountains will get 2-4 inches of snow with the northern ranges getting 1-2 inches.
Since early this morning a fast moving storm has dropped nine inches of snow in the Bridger Range, 2-3 inches in the northern Madison and Northern Gallatin Ranges and a trace to one inch elsewhere. Currently, mountain temperatures are in the teens around Big Sky and low to mid-twenties over the rest of our advisory area. Winds are blowing 15-30 mph out of the WSW with gusts reaching close to 40 mph. Today, temperatures will warm into the high 20s to low 30s F and winds will continue to blow 25-35 mph out of the WSW. Snow will end late this morning but skies will remain mostly cloudy through the day. A warm and dry pattern will settle in this afternoon and remain in place through tomorrow.
This morning skies are clear, temperatures are ranging between the mid-twenties to low thirties and winds are blowing out of the WSW at 15-25 mph. Today, skies will be partly cloudy, temperatures will warm into the mid-thirties to low forties and winds will continue to blow out of the WSW at 15-30 mph. A change in the weather will take place this evening as a cold front approaches from the west. Skies will become mostly cloudy by tonight and temperatures will be cooler than what we’ve seen the past few days. Unfortunately there is very little moisture associated with this cold front.
High pressure continues to dominate the weather pattern. At 4 am this morning mountain temperatures are ranging between the high twenties to low thirties in the north and low to mid-twenties in the south. Winds are blowing 10-20 mph out of the WSW and skies are clear. Today, temperatures will warm into the high thirties to low forties in the north and low to mid thirties in the south. Winds will continue to blow 15-25 mph out of the WSW. Warm and dry conditions will prevail through the weekend.
The past two days have started with cold temperatures which have limited daytime warming. This morning, however, temperatures were in the high 20s F. Winds were blowing 10-15 mph gusting 20-30 mph from the W and SW. A ridge of high pressure will dominate today’s weather and provide clear skies with lots of sunshine. Cloudy skies this morning shouldn’t last very long, and winds should remain about the same. Temperatures will approach 40 degrees F in most areas although the Bridger Range could see temperatures approaching 50 degrees F.
A ridge of high pressure continues to build over the area and will bring more sun and warmer temperatures today. This morning temperatures were in the low-mid teens F, and westerly winds were averaging 10-15 mph with gusts of 20 mph in most places. They were much calmer further south near Lionhead and the Taylor Fork while further north in the Bridger Range they were blowing 30-35 mph. Today should be noticeably warmer with temperatures near 32 degrees F and westerly winds averaging 10 mph with gusts of 20 mph although stronger winds should continue in the Bridger Range.
Yesterday’s storm dropped 4-6 inches of snow throughout the advisory area except the northern Bridger Range which only received about an inch while only a few miles south, Bridger Bowl received 5 inches. Overnight skies cleared and temperatures dropped to the negative single digits F. Wind speeds and directions have varied considerably. In general winds were blowing strong early yesterday from the SW, calmed midday, then increased last evening from the NW blowing 15-25 mph. In some places like Hyalite winds have been very calm since yesterday while other places like Bridger Bowl and Lionhead they increased overnight. Today will be clear and sunny with temperatures climbing into the low 20s F. Winds will remain varied over the advisory area but will mostly blow from the W and N at 10-15 mph with gusts of 25 mph.
This morning mountain temperatures are in the mid-20s after hitting the low 40s yesterday. Winds are still blowing west to southwest at 30-40 mph, but were blustery yesterday afternoon with gusts reaching the high 50s. A fast moving cold front with snowfall is hitting Bozeman as I type this at 6:00 a.m. Temperatures will drop into the upper teens, winds will remain steady out of the west to southwest and the mountains will get a few hours of intense snowfall. I expect 4-6 inches will accumulate before skies clear tonight. High pressure and sunny skies are on the menu for the rest of the week.
