2011 goes out with a bang with snowfall measured in feet not inches. Since yesterday morning the mountains around Cooke City received 2 feet of snow. The mountains near West Yellowstone, the southern Madison Range, and the Bridger Range received 1 foot of new snow. Yes, that’s right the Bridgers got snow! The mountains near Big Sky and Hyalite Canyon received 6-9 inches of new snow. Strong winds continued as well and were blowing 20-40 mph this morning. They were blowing from the SW yesterday afternoon and shifted to the NW this morning. Temperatures were in the low teens F.
Snowfall ended this morning, and today skies will slowly clear allowing some sunshine. Winds will blow 15-20 mph from the WNW with gusts 30-35 mph. Temperatures may drop a bit more into the single digits F.
It snowed all day yesterday near Cooke City where an additional 12 inches of snow fell since yesterday morning. The Big Sky area and Hyalite Canyon received another 3-5 inches while further south near West Yellowstone and the Taylor Fork, the mountains received another 2-3 inches. The Bridger Range got a touch of rain yesterday and 1 inch of snow fell early this morning. Strong winds continued with gusts of 60-80 mph and steady 30-40 mph winds from the W and SW. This morning winds eased slightly and were blowing 25-40 mph from the SW. Temperatures were in the mid 20s F.
Snow was falling this morning at 4 a.m. and more will fall today and tonight. Guess which area will get the most snow? That’s right, the mountains near Cooke City will get another 16-20 inches. Mountains near West Yellowstone will get 10-12 inches, and mountains near Big Sky and south of Bozeman will get 6-8 inches. In the Bridger Range there will be a tug-of-war between snowfall and downslope winds which tend to limit snowfall. It’s hard to say who will win, but 2-4 inches should accumulate by tomorrow morning. Despite plentiful snow it may be hard to tell how much has fallen because winds will remain strong. Today they will blow steady at 15-20 mph gusting 40-60 mph from the SW. Temperatures will warm near 30 degrees F but a cold front moving over the area tonight will drop temperature into the single digits by tomorrow.
Since yesterday the mountains near Cooke City received 7-9 inches of snow and the mountains near Big Sky, the Taylor Fork and West Yellowstone received 4-5 inches.

All areas have temperatures near 30 degrees F and very strong winds blowing 15-30 mph from the W with gusts of 40-50 mph. Today temperatures should drop to near 20 degrees F by afternoon and strong winds will continue. A little more snow will fall this morning, then snow will return tonight and through Friday. By tomorrow morning most areas especially mountains from Big Sky south will receive 1-3 inches of snow.
This morning is warm and windy with fresh snowfall in the southern mountains. Four inches has fallen near Cooke City with 1-2 inches accumulating from the Yellowstone Club to West Yellowstone. Mountain temperatures are in the mid to high 20s as westerly winds average 30-40 mph with gusts hitting 50 mph. The jet stream will keep winds strong and create favorable dynamics for snowfall. By morning there could be 1-2 inches in the northern mountains and 6-8 inches in the southern ranges.
Currently, under cloudy skies, mountain temperatures are in the teens with westerly winds blowing 20-30 mph. A quick moving system will roll through this morning on a west to northwest flow. Winds will increase with gusts reaching the 40s and snow will fall, but it won’t amount to much—only 1-2 inches in the mountains. Another shortwave disturbance is lined up to hit us again tomorrow. Wow, two storms in one week. Could this be La Nina knocking at our door?

It looks like the boys and girls of SW Montana have been bad this year and will not get any snow for Christmas. Instead of coal in our stockings, it looks like we’ll get a good dose of wind.
