Jackson squeezed out another 7 inches on Friday! Conditions on the pass or upper mountain of JHMR or Targhee (4 inches) would have continued to exceed expectations (4 powder days in a row). Steamboat grabbed 4 inches overnight so early Saturday will offer fluff on top of the 21 inches that fell in the past 72 hours. It's still snowing lightly in Colorado favoring mountains north of I-70.
The final wave of powder will come Sunday/Monday with a cold front that moves down from Montana through Wyoming and Colorado.
Northwest winds in Montana will favor Bridger Bowl and Big Sky. It's not a moist system and fast moving. You may find light snow Sunday turns a bit moderate by 3 PM. Monday morning is likely to offer 2-5 inches of powder for many of the southern MT resorts. Further north, the bulk of moisture skirts east of Whitefish into the higher peaks of Glacier National Park. Lighter amounts will fall at Whitefish. Some snow will also be falling near Red Lodge Mountain albeit light.
The Tetons get grazed Sunday night with a better shot of snow for the Front Range Mountains of Colorado near Denver on Monday. Resorts like Eldora, Loveland, Winter Park, and A-Basin could see a final tease of 2-4 inches (Ride Monday). Further west, amounts will be less.
The weather pattern will bring high pressure for much of next week before the trend moistens up late in the period. it's possible that by next weekend snowfall returns to many areas including the PNW, Sierra, and much of the Rockies. Models are not in agreement on who gets the most snow. I'm a bit more confident for Idaho, Wyoming, and the PNW than the Sierra but it's only a hunch. We will have to wait and see what the trend of the long range models are in the next 2-3 days to gain better confidence. The East gets active by Tuesday night (Chowdah).
