Yesterday, light, steady snowfall dropped 1-2 inches from the Yellowstone Club to West Yellowstone to Cooke City. Winds were out of the southwest blowing 15 mph and calmed even further last night. Under clear skies, mountain temperatures this morning are in the low teens but will rise into the 20s. A moist southwest flow will increase clouds and bring snowfall to the southern mountains tonight with another 1-2 inches of snow by morning.
Only remnant flurries fell after yesterday's early morning storm. Temperatures reached the 20s and ridgetop winds blew 15-20 mph from the west-southwest. Today will be mostly cloudy with mountain temperatures again reaching the mid 20s before dropping to the low teens tonight. Ridgetop winds will continue to be west-southwest at 15-20 mph. A few bands of moisture may drop a dusting of snow, but it won't be enough to really care about.
A cold winter storm system has impacted southwest Montana depositing 8-10 inches of new snow in the Bridger Range with 5-7 inches falling throughout the rest of the advisory area. Winds have picked up overnight and have been constant along the ridgetops at 20-30 mph out of the W-NW. Snow and winds will decrease throughout the day and temperatures will be on the cooler side with highs in the twenties and lows in the single digits.
A ridge of high pressure has dominated our weather pattern over the past 24 hours bringing us sunny skies and calm conditions. This ridge will break down today as a weak low pressure system pushes in from southern Idaho.
Winds are currently calm out of the W-SW at 5-15 mph, but will increase as the day progresses to 15-25 mph along the ridgetops. Temperatures will remain mild today with highs in the upper 20's to low 30's F, but will cool off this evening with lows in the teens. The impact of this system will be felt more in the southern mountains which could pick up 6-8 inches of snow by tomorrow morning with the northern ranges picking up less than half that amount.
A weak ridge of high pressure has produced partly cloudy skies and calm conditions over our area for the past 24 hours. Today, temperatures will be on the mild side with highs in the mid to upper thirties and lows in the twenties. Winds will be calm in the lower elevations, but will reach 15-20 mph out of the W-SW along the ridgetops. The existing ridge will begin to break down today bringing a better chance of unsettled weather tonight and tomorrow.
Today will be another beautiful one to be in the mountains. This morning temperatures were in the high teens and low 20s F with ridgetop winds blowing 5-15 mph from the WSW and WNW except in the Bridger Range where they were blowing 20 mph. With an upper level ridge of high pressure, no precipitation is expected until later this weekend. Some high clouds and sun are expected today with high temperatures in the upper 20s F and winds blowing 5-15 mph mostly from the west.
Lingering snow showers yesterday only added a trace of snow before skies cleared as high pressure moved over the area. With clear skies overnight temperatures dropped into the mid to low teens F while valley temperatures were a bit lower. Westerly winds were blowing 5-10 mph this morning and should remain the same today when skies will be mostly sunny and temperatures will reach the upper 20s F.
Light, but steady snowfall dropped 5 inches outside Cooke City, up to 4 inches in the southern Madison, 2-3 inches around Big Sky and the Bridger Range and 1 inch in the northern Gallatins. Westerly winds are still light at 5-10 mph with temperatures in the mid teens at 6 a.m. A few lingering showers will only drop a trace of snow this morning before high pressure nudges this system out. Under partly cloudy skies mountain temperatures will hit the mid 20s again, but dip into the single digits tonight. Ridgetop winds are forecasted to remain light.
Yesterday, scattered snow in the southern mountains deposited 1-2 inches while the mountains from Big Sky and points north only saw a trace to an inch. Southwest winds are light at 5-10 mph with mountain temperatures reading 15-20F. Today, cloudy skies will dominate our region from a moist southwesterly flow. Winds are expected to remain light as temperatures warm into the 20's before dropping to 10F tonight. Snowfall is expected this afternoon in the mountains from Big Sky southward with 2-4 inches falling by tomorrow morning. The northern mountains will only see a trace to 1 inch.
A massive low pressure system has moved out of our area and is now sitting over the midwest, continuing to suck cold air from Canada southward into Montana. This low pressure system was responsible for delivering 2-3 inches of new snow to the Bridger Range in the past 24 hours with a trace to 2 inches falling over the rest of the advisory area. Winds have been out of the NW at 15-20 mph, but will calm and shift to the west as the day progresses. Cold and dry conditions will exist over our area for the rest of the day with highs in the 20's and lows in the single digits.
