Yesterday morning a trace to 1 inch of snow fell from Big Sky to the southern ranges. Light southwest winds are still blowing 5-15 mph as temperatures cooled into the teens last night from their highs in the 20s.  Mild weather will continue today with temperatures reaching the low 20s, light southwest winds and partly cloudy skies.  West Yellowstone may only get a trace of snow late tonight, but don't despair, snow is forecasted for late Friday. 

A moist southwest flow clouded up our skies and dropped an inch of snow in the southern Madison Range last night. This morning, winds are 10-20 mph out of the south-southwest with mountain temperatures in the mid 20s.  Clouds will continue today and winds will decrease tonight. In the next 24 hours weak dynamics will only wring 1-2 inches of snow in the southern mountains.   

Over the past 24 hours a ridge of high pressure has brought sunny skies and warmer temperatures to southwest Montana.  Today that ridge of high pressure will break down as a front approaches from the southwest. Snow and wind will arrive with this front bringing 1-2 inches to the southern mountains while the northern mountains will remain mostly dry.  Strong ridetop winds out of the W-SW at 25-35 mph will be present for most of the day.  Temperatures will remain warm with highs in the upper 30's and lows in the 20's.  Conditions will calm this evening, but another band of moisture will move into southern Montana tomorrow morning bringing an additional 1-2 inches of snow to the southern mountains.

During the past 24 hours a westerly flow has brought cloudy skies, mild temperatures and light precipitation to southwest Montana. A trace of new snow has fallen in the Madison Range and the mountains around Cooke City.  This flow will continue throughout the day today, bringing a slight chance of snow to the southern mountains and producing ridgetop winds out of the W-SW at 15-20 mph.  Temperatures will stay warmer in the northern ranges with lows in the 20s and highs breaking 40 F degrees.  The southern mountains around West Yellowstone and Cooke City will stay slightly cooler with highs around freezing and lows in the teens.

This morning temperatures were in the mid-high 20's F except in the mountains near West Yellowstone where they were in the teens F.  Winds increased overnight and this morning were blowing in the 30's and 40's from the W and SW  Today will start mostly sunny with clouds increasing this afternoon.  Temperatures will rise to near 32 degrees F and winds will blow 20-30 mph from the WSW.

After 7 a.m. yesterday another inch of snow fell in most areas bringing the storm total to nearly 3 inches.  Overnight partially clear skies allowed temperatures to drop into the high teens and low 20's F.  Today will be partly sunny with temperatures reaching the low 30's F.  Strong winds will be the most exciting part of the forecast.  This morning they were blowing in the 30's mph from the W at the Bridger Ridge while blowing 15-35 mph SSW near Big Sky and much calmer near West Yellowstone and Cooke City.  Expect winds to increase early this afternoon when they will blow 20-30 mph from the WSW with gust in the 40's especially in the Bridger Range.

Early this morning it was snowing and 1-2 inches had accumulated in the mountains by 7 a.m.  Unfortunately this fleeting storm will only lay down another ½ to 1 inch of additional snow.  Temperatures were in the low 20's F and will rise into the upper 20's today under mostly cloudy skies.  Light winds were blowing from the W and SW at 5-10 mph while stronger ridgetop winds in the Bridger Range were blowing about 20 mph.  Today winds will continue at these speeds blowing from the W and slightly NW.

Last night 2-3 inches of snow fell in the southern Madison Range with an inch falling near Cooke City and the Yellowstone Club.  Yesterday's strong southwest winds gusted into the 40s, but have lessened to 20-30 mph and will calm even further today.  Mountain temperatures warmed to a few degrees above freezing, but cooled overnight into the high 20s. Under mostly cloudy skies temperatures will still hover near freezing. A weak southwest flow will create a few isolated showers bringing an inch of snow to the southern mountains. 

Yesterday was another day of sunny skies and above normal temperatures.  Mountains warmed into the 30s with 10-20 mph southwest winds.  Last night things only cooled to just below freezing in the northern ranges and 20's in the south.  Sunny skies will prevail this morning, but clouds will increase this afternoon.  Temperatures will mirror yesterday and winds will be out of the southwest at 15-25 mph. The mountains around Cooke City and West Yellowstone could see a trace to one inch of snow overnight.

If you enjoyed yesterdays beautiful weather than you will definitely like the weather today.  High pressure has created carbon copy weather over the past couple days and will continue to do so through tomorrow.  Warm and dry conditions will prevail today, sending high temperatures close to 40 F degrees with lows falling into the teens.  Winds will remain light in the valleys but will pick up this afternoon out of the west at 15-20 mph along the ridgelines.  The dominating high pressure will begin to break down starting Wednesday morning, bringing with it a slight change in conditions.
