Yesterday was a beautiful day to be in the mountains, and it looks like Santa won’t need Rudolph to guide his sleigh tonight as dry weather should continue. This morning temperatures were in the high teens F and westerly winds were blowing 5-15 mph. Today will see lots of sunshine as temperatures warm to near 32 degrees and winds will remain light. The Grinch can’t steal Christmas, but it looks like he took our snowfall for the moment.  Measureable snow accumulations shouldn't come until early next week.

Overnight the mountains near Cooke City and West Yellowstone received 3-4 inches of snow while all other areas received 1-2 inches. Temperatures this morning hovered near 20 degrees F with westerly winds blowing 5-10 mph. Today temperatures should rise into the mid-upper 20s and winds will remain calm. Mostly cloudy skies will produce some snow in the southern parts of the advisory area but only a trace should accumulate. Further north, skies will have a mix of sun and clouds. The next chance of snow doesn’t arrive until after Christmas.

Yesterday’s weather was beautiful and uneventful: sunny skies, calm winds and temperatures in the low 20s. In the next 24 hours small weather disturbances will create mostly cloudy skies in the southern mountains and partly cloudy up north. Winds will remain light out of the southwest at 5-10 mph as temperatures rise into the 20s from their current readings in the teens. Some flurries may fall around Cooke City and West Yellowstone, but it should measure less than an inch. The weather through the Christmas weekend is looking dry and warm—no gifts of epic pow from Santa this year.   

Today is the shortest day of the year. From this date forward we’re starting our climb toward summer, but with a forecasted high of 20F today I’m not digging out my flippity-flops just yet. Yesterday, strong west to southwest winds blew 30-40 mph before calming last night to 10-15 mph. Under clear skies mountain temperatures are near 10F. Some clouds will penetrate our southern mountains, but the next 24 hours will be a quiet weather pattern of light winds and no precipitation.  

A fast moving storm deposited 10-12 inches of snow in the mountains around Cooke City and West Yellowstone totaling close to an inch of water. 4-5 inches has fallen in the mountains around Big Sky and 2-3 inches has accumulated in the Bridger and northern Gallatin Ranges. Winds are blowing constant at 15-25 mph out of the W-SW with stronger gusts reaching close to 50 mph. Mountain temperatures are ranging from the mid-teens to low twenties F. Today, snowy and windy conditions will persist with an additional 1-3 inches possible in the mountains by this evening. A ridge of high pressure will begin to build tonight into tomorrow bringing a break in the weather.

Over the past 24 hours 3-4 inches of new snow has fallen in the mountains around West Yellowstone and Cooke City while the northern ranges picked up 1-2 inches. Mountain temperatures are in the mid-teens to low twenties F and winds blowing out W-SW at 10-20 mph with a few gusts reaching into the 30’s. Southwest Montana will see a break in the weather this morning, but another wave of moisture will arrive into our area by this evening. Winds will increase throughout the day as this next storm system gets closer. The southern half of our advisory area will likely pick up an additional 4-6 inches by tomorrow morning while the northern half will pick up 3-4 inches.

This morning temperatures were only a few degrees above zero F and calm SW winds were blowing 5-10 mph with a few gusts reaching 20 mph. Things should change today as a strong Pacific storm system moves inland mostly through CA, NV and UT. Winds will increase to 15-30 mph from the SW and temperatures will reach the mid teens F. Snowfall should begin this afternoon with about 4 inches accumulating by tomorrow morning in the northern half of the advisory area and 4-6 inches in the southern half.

Yesterday’s weather made a perfect day to be outside, and today’s weather should bring more of the same except for cold temperatures. This morning southerly winds were blowing 10-15 mph, and mountain temperatures were near 0 degrees F except in the Bridger Range where temperatures were near 10 degrees F. With an inversion this morning some valley temperatures were much colder as in West Yellowstone where temperatures were -20 F. Today winds will remain mostly calm, skies will be mostly sunny, and temperatures will rise to the mid teens F.

No snow fell overnight. Temperatures dropped into the upper single digits F, and westerly winds this morning were blowing 5-15 mph. Today’s weather will be mostly dry, cold, and calm. Under partly sunny skies, temperatures will warm into the mid to upper teens F and calm winds will blow 5-10 mph.

A fast moving cold front and blizzard conditions moved through yesterday afternoon. Southwest winds were gusting to 70 mph as we got pelted by ball bearing shaped graupel snow. Two to three inches fell in the mountains around Bozeman, 3-5 inches near Big Sky, 7 inches in Taylor Fork and a foot near West Yellowstone and Cooke City. Temperatures are in the single digits and winds are west to southwest at 15-25 mph. Today will be beautiful with partly cloudy skies and temperatures reaching the high teens.
