Montana Daily Snow

Snowy and Windy Across the Northern Rockies
Summary
Several waves of energy will be moving through the Northern Rockies in the next 6 days growing our snowpack numbers. The first wave on Monday and Tuesday will bring strong W/SW winds to 50 mph along with snow totals of anywhere from 2 to 12 inches across Montana’s mountains. A second wave Thursday night into Friday could bring similar results. A third Friday night into Saturday adds a few more!
Short Term Forecast
West of the Continental Divide:
Monday morning’s snow reports have delivered 3 overnight inches at Lookout with 1 inch at Whitefish and Snowbowl. Expect snow during the day Monday at all these areas with the heaviest accumulations falling at Lookout and Snowbowl with 4 to 6 inches likely. Whitefish, which has been just north of the heavier moisture feeds in February will see 1 to 3 inches. Whitefish will also experience strong W/SW winds with gusts to 50 mph on the summit. Discovery will see snow showers with 1 to 2 inches possible. Seasonally warm temps will have snow levels in the 5000’ vicinity. It will also be a very windy day across the high terrain on Monday with gusty West/SW winds to 50 mph possible.
Monday night, better chances of more widespread snow across the region as a cold front merges with residual Pacific moisture that looks to bring around 4 to 8 inches at Discovery, Snowbowl and Lookout with 2 to 4 at Whitefish. Snow continues Tuesday with another 1 to 3 inches likely for all. Daytime temps come crashing back down to seasonable averages Tuesday. West winds will be gusty across the ridgetops finally laying down a bit during the afternoon hours.
A brief break with dry skies and numerous sunny spells on Wednesday along with upper mountain daytime highs in the low 20’s. Upper mountain winds (W/SW) will finally calm down across the region.
Active weather returns Thursday when a complex low pressure system enters the region with widespread snow showers that look to bring an inch or three to most areas across the region with slightly higher amounts at Lookout Pass.
Friday, unsettled skies continue with periods of snow, mainly around and south of I-90, with continued seasonable daytime temps.
East of the Continental Divide:
Monday will be a windy and mild day with gusty SW winds at Big Sky, Bridger and Red Lodge that could likely affect upper mountain lift ops with wind holds. Gusts of over 40 mph will be likely across the ridgetops. Skies will be partly cloudy with upper mountain high temps rising to near 32 degrees, with 40 degrees at Red Lodge.
A vigorous cold front invades Monday night into Tuesday triggering snow (and more winds) with moderate amounts of 4 to 8 inches likely for Big Sky and 2 to 4 at Bridger Bowl through last chair Tuesday. Red Lodge will see a slight chance of an inch or two. Temps will be about 10 to 15 degrees colder on Tuesday, but strong West winds will be a factor across the high terrain gusting to around 45 mph.
A mix of some sun and clouds, colder daytime temps and even a few flurries will be the story for Wednesday and Thursday across the Eastside. High temps across the upper mountain terrain will range from 12 to 18 degrees across the region.
A Pacific storm system rides through Thursday night into Friday bringing back measurable snow into the forecast for the SW mountains of Big Sky, Bridger and Maverick. Temps will continue to be cold but seasonable keeping the excellent snow quality in check. Stay tuned for updates on this developing storm system.

Extended Forecast
West of the Continental Divide:
Friday night into Saturday colder air drawn in by Friday’s storm system will bring back measurable snow amounts in the 3 to 5 inch range from Lookout Pass south to Lost Trail Pass. Lesser amounts are expected at Snowbowl and Discovery with Blacktail and Whitefish largely missing out on any accumulations.
Dreaded high-pressure is depicted to move in Sunday into early next week drying things out for several days.
East of the Continental Divide:
Snow continues across the SW and along the Divide on Saturday adding another several inches to our growing snowpack. A reinforcement of colder air on Saturday will accompany the snow as well keeping daytime highs in the low to upper teens across the region’s high terrain.
Models are coming to better agreement on a ridge of high-pressure that looks to bring dry skies and a warming trend to the region Sunday through the middle of next week.
