Moderate to heavy snow is likely today over the Pacific Northwest with all action moving east over the northern Rockies late today and tonight. The sierra is getting teased with some light snow falling at most areas last night. The highlights in the Rockies may end up being central Idaho with the Tetons on watch. Colorado gets a tease for Saturday morning with some more snow possible in the extended forecast.
Short Term Forecast
Snow if falling over the Sierra today with where 2-5 inches has fallen at upper elevations in many areas. A cold front will swing east today enhancing snow in the Pacific Northwest (WA and OR) with 8-12 inches likely over some favored spots like Mount Hood, Timberline Lodge, Stevens Pass (Convergence zone of cold air along and north of I-90) and perhaps spots just east of Seattle like Alpental or Snoqualmie Pass.
Snow will enhance over most of Idaho today with cold air and a decent shot of 6-12 inches over Brundage extending south into Sun Valley (2-5) through tonight. Spots from Galena Summit and north towards Stanley may see higher amounts. "If I were chasing I would stay north of Jackson and perhaps head to Brundage if this was mid winter."

Action moves east into the Tetons late today and tonight with models pumping out 4-7 inches over Grand Targhee and Jackson Hole Mountain at upper elevations. 1-3 inches is possible at lower elevations. Northern areas of the Tetons may grab 5-10 inches through late Saturday night. Snow showers with a slight warming trend will continue through Sunday so its possible that higher amounts are found by late this weekend over the Tetons (Several waves of light snow Saturday/Sunday).
Colorado is getting teased with the slim picking leftovers late Friday night and early Saturday with my expectation of 1-3 inches over a wide area of locations of the northern and central mountain ranges. It's not exciting but who cares "Its October".
Canada had a good run of POW in the past several days especially the peaks of many resorts on the interior where 1-2 feet has fallen. Below: Summit of Kicking Horse Resort
Heavy snow in the Pacific Northwest today migrates to warmer conditions for the weekend. Snow will change to rain at most elevations of the resorts late Saturday/Sunday with a drying trend likely for a good portion of next week. Snow showers will linger in the northern Rockies this weekend with high pressure for the early to mid week period. It's possible another cold front comes down over eastern or central Wyoming next Thursday and impacts the front range of Colorado late week?
While the trend this season has been more snow in the northern Rockies it's way too early to draw any long term conclusions. Conditions change and from my experience areas in the skunk hole can be deep in a short period of time. What is interesting to me thus far is respectable teases have been found in most spots of the west including the PNW, Montana, Utah, Tetons, Colorado (South and north). Its only October!
Please follow the Chase for the deepest snow. This post is updated as conditions change. I am still in Mountain Bike mode in Boulder and kudos to Full Cycle Bike Shop that just built up my brand new rig that will be on the trails this weekend. Stay safe as deep turns are on there way soon If your in the PNW start hiking as the bases especially in Oregon are respectable for some fun early season turns. Be aware of low tide! My assumption is Timberline, Hood, Bachelor all grab respectable numbers.
