Yesterday another 2-3 inches of snow fell in most areas except the southern Madison Range and the mountains near West Yellowstone which only got a trace. This morning temperatures were in the teens F and ridgetop winds were blowing 10-20 mph from the WNW. In the Bridger Range ridgetop winds were blowing 35-40 mph. Today will have sunshine and temperatures in the mid to high 20s F with little change in the winds. The next chance for snow may be Sunday evening.
Curious why La Nina hasn’t brought more snow to SW Montana? Read a brief explanation from the National Weather Service office in Missoula here.
Yesterday an additional 1-2 inches of snow fell. Not much, but a little snow is better than none at all. This morning winds were blowing 15-20 mph from the SW with temperatures in the low teens F. Today will be mostly cloudy and temperatures will be in the high teens F. Winds will increase and blow 15-30 mph from the W. Late this afternoon some moisture should arrive from the north but only produce 1-2 inches of snow. Long range models indicate more snow for the rest of December. Keep your fingers crossed.
Ask and you shall receive. Four to six inches of low density snow fell in the northern mountains early this morning. The Club got four while Bridger Bowl measures six. The southern ranges got two to four inches. Winds are westerly and averaging 10-15 mph with occasional gusts to 30 mph, except on the ridge at Bridger Bowl where they are blowing 30-45 mph. Mountain temperatures are in the teens. Another inch or two will fall this morning before tapering off. This afternoon skies will turn partly cloudy and westerly winds will lessen to 10-20 mph.
Montana is officially diagnosed with PDD; Powder Deficit Disorder. La Nina is the cure, but she’s playing hard to get. We have not had snow since last Monday and there’s none forecasted in the next 24 hours. Like a pauper with cupped hands I’m hoping that Thursday will bring a few flakes. This morning mountain temperatures are in the high teens with southwest winds blowing 10-15 mph at the ridgelines. Today, morning clouds/fog will give way to mostly sunny skies with light winds.
A split jet stream is diverting active weather patterns to the north and south, leaving southwest Montana in a doughnut hole. Currently mountain temperatures are in the mid teens F and winds are blowing 5-15 mph out of the SSE under partly cloudy skies. Today, temperatures will warm into the mid 20s F and winds will shift to the SSW blowing 10-20 mph.
High pressure remains the dominant weather pattern over southwest Montana. This morning skies are clear and mountain temperatures are between 15-20⁰ F. Winds are blowing out of the WSW at 5-20 mph. Today, skies will start out clear but become partly cloudy by this afternoon. Temperatures will rise into the mid 20s to low 30s and winds remain light out of the WSW.
Over the past 24 hours a ridge of high pressure has kept conditions dry with seasonal temperatures. At 4 am this morning mountain temperatures are ranging from the mid teens to low 20s F with Madison Plateau near West Yellowstone being the cold spot at 1⁰ F. Winds are out of the WSW at 5-15 mph. Today temperatures will reach the mid 20s to low 30s F and winds will blow out of the WSW at 10-20 mph. Skies will become partly cloudy by this afternoon as the ridge begins to flatten.
No snow fell since yesterday and skies were clear overnight. Temperatures this morning were near 10 degrees F and westerly winds were blowing 15-30 mph. In some places they blew from the SW while in other places they blew from the NW. Today will have clear skies and sunshine. Temperatures should reach the mid 20s F and winds should continue blowing westerly at 15-30 mph.
Most places remained dry or received a trace of snow overnight except the mountains near Cooke City where 1 inch of new snow fell. This morning temperatures were in the low teens F and winds were blowing 10-15 mph with gusts of 20-30 mph mostly from the NW. Skies will clear today as drier air moves over SW Montana. Temperatures should warm into the low 20’s F and winds will remain unchanged. The forecast appears to be dry though the weekend, with great weather for the Ice Festival in Hyalite Canyon.
Since our last forecast on Monday morning no new snow has fallen in southwest Montana. Mountain temperatures were near or below zero early in the week, but have warmed substantially. This morning they read in the low 20s around Bozeman, in the teens near Big Sky and the single digits in West Yellowstone and Cooke City. Winds have been westerly at 15-30 mph. A small disturbance will drop in from Canada tonight. The winds will shift to the northwest as temperatures drop into the single digits with a trace to one inch of snow falling. It’s not very exciting and I’m unhappy to report that dry weather is forecasted through the weekend.
