Weather
A windy, springlike start gives way to the main event from Wednesday through Saturday, when a broad storm should bring 12"-24" to the best terrain and a meaningful refresh across most open Northern Rockies resorts. Confidence is highest from Wednesday morning, April 1, through Saturday afternoon, April 4, when timing and snow-level trends line up best. After that, the region should turn back toward milder spring skiing, with only lower-confidence chances for smaller follow-up snow later in the window.
Sunday through Tuesday looks more like a transition than a true storm cycle, with only 1"-5" of new snow favored at the Idaho Panhandle and northwest Montana resorts while wind and cooling do more of the work elsewhere. Guidance is fairly well converged on the Sunday afternoon through Monday cold front and on snow levels falling from roughly 5,000-8,000 feet ahead of it to 3,000-5,000 feet afterward. Early SLRs mostly run in the 7-10 range, so any refresh should come in fairly dense before colder air firms things up Monday night. The bigger spread is south and east of there, where some solutions keep Tuesday mostly dry while others squeeze out scattered mountain snow showers. Wind impacts are less settled than the basic cooldown, but exposed ridges still look likely to gust 30-45 mph and a few higher peaks from southwest Montana into northwest Wyoming can push 50-60 mph.
From Wednesday into Saturday, guidance is converging on a widespread storm that should deliver 4"-27" across the region, with the strongest open-resort upside at Big Sky, Grand Targhee, Brundage, and Jackson Hole. Timing agreement is solid on snow ramping up Wednesday, peaking Wednesday night through Thursday, then tapering to colder wraparound snow Friday into early Saturday, while the main remaining spread is exact intensity at Big Sky, the Tetons, and a few closed Idaho and Montana hills. Snow-level guidance is also clustered on a fall from roughly 5,000-7,000 feet Wednesday to 3,000-5,000 feet by Thursday night and Friday, so lower elevations may start wetter while upper mountains improve with time. Snow quality should follow that trend, with SLRs often in the 6-10 range early, then rising into the 12-18 range as colder air settles in. Wind impacts during the storm look more mixed than the snowfall signal, generally manageable in the west but breezier along exposed southwest Montana and northwest Wyoming ridges. The best powder-chasing window at open mountains looks to be late Wednesday night through Friday, while Bridger Bowl and Tamarack also score notable snow but are currently closed.
After the storm exits Saturday, most guidance points to a drier and milder stretch through at least early next week, which should push the Northern Rockies back toward classic spring conditions. That matches the broader warmer-than-normal signal across Idaho, Montana, and Wyoming, with drier tendencies strongest in Idaho and western Montana. Guidance diverges again later in the period, with a few solutions trying to bring smaller snow chances around Tuesday and again next weekend, but the spread is wide enough that only scattered, lower-end refresh potential makes sense for now rather than another region-wide reload.
