Since yesterday, the mountains near Cooke City received 10 inches of snow, near Big Sky 4-6 inches of snow, and 2-3 inches most other places. This morning winds were averaging 20-30 mph from the W and NW with gusts of 40-60 mph. Temperatures were in the single digits to low teens F. Today, another 1-2 inches should fall and temperatures should bottom out at 0 degrees F before warming back up a few degrees. Fortunately winds should ease by afternoon and blow 10-20 mph from the NW. Tonight through Sunday should be dry with more snow coming Sunday night.
Overnight the northern Madison and northern Gallatin Ranges and the mountains around Cooke City received 7-10 inches low density snow (5% density). The Bridger Range received 5 inches. The mountains near West Yellowstone including the southern Madison and southern Gallatin Ranges received 1-2 inches. This morning temperatures were mostly in the low to mid-teens F and westerly winds were averaging 15-20 mph with gusts of 30 mph. In Hyalite Canyon winds were averaging 28 mph and gusting to 50 mph.
A few more inches of snow should fall this morning. Today temperatures will struggle to reach the low 20s F and westerly winds will continue blowing 15-30 mph. Snowfall will return this evening with similar amounts as last night if not more. This weather pattern has a slight NW flow and more energy associated with it than last night. I don’t think this pattern will favor the Bridger Range more than other areas….but there’s a chance. By tomorrow morning most places should get 8-12 inches of new snow.
Yesterday rain fell in the valleys and snow fell in the mountains. Near Bozeman and Big Sky 1-3 inches of dense snow fell. Near West Yellowstone and Cooke City 3-5 inches of dense snow fell. Overnight temperatures dropped to the high teens and low 20s F. Winds eased a little since yesterday and were blowing 15-25 mph from the WSW this morning. Both winds and temperatures shouldn’t change much today, and snowfall will return sometime this afternoon or early evening. By tomorrow morning most areas will receive 3-5 inches of snow with more coming Friday night followed by much colder temperatures for Saturday.
Unseasonably warm temperatures reached the mid-thirties at 8,000 feet. The new snow was on the cusp of being rain. The southern mountains picked up .7 to 1 inch of Snow Water Equivalency (SWE) which measured 3-6 inches of new snow. Around Bozeman .2-.3 inches of SWE fell measuring only a trace of snow while the Big Sky area got two inches. Winds are averaging 15-25 mph out of the west to southwest with gusts of 40 mph. Later this afternoon, temperatures will drop into the low 20s with gusty winds and 2-3 inches of snow falling in the southern mountains.
Under partly cloudy skies there’s no new snow to report. Mountain temperatures are in the teens to 20 degrees this morning with southwest winds averaging 10-20 mph and gusts to 30. A moist pacific system will increase cloud cover today. Winds will remain moderate as temperatures rise into the upper 20s. In the southern mountains 1-2 inches of new snow will fall by morning. The weather models show unsettled weather, so my hopes are high for more snow this week.
Since yesterday morning Carrot Basin Snotel site in the southern Madison Range picked up 1.4 inches of SWE (snow water equivalent) while Madison Plateau and Fisher Creek are showing close to one inch of SWE.
