"An active, multi-wave pattern will keep the Northern Rockies in on-and-off snow through Tuesday night, with the best totals focused on Idaho and the Idaho Panhandle plus parts of interior British Columbia. The first push is relatively mild with higher snow levels at times, so several areas see denser, more supportive snow early, then a colder transition Sunday night into Monday drops snow levels and improves quality."
"Friday night through Sunday will feature a milder, moisture-rich push that favors higher terrain while flirting with elevated snow levels at times. Snow levels run relatively high for parts of Idaho and the inland Northwest during the core of this wave, so the early snow can come in dense, especially where SLRs hover in the 7-11:1 range. That points to heavier turns at times at places like Schweitzer and Bogus Basin, and similarly "right-side-up" snow across the interior BC resorts early in the window."
"Sunday night into Monday marks the cleaner quality upgrade as colder air lowers snow levels and boosts SLRs across much of the region. Snow levels trend downward into the 2,000-4,000 feet range in many zones, with pockets dropping even lower by Monday night, and that lines up with improving ratios, commonly 12-15:1, for a drier feel on top. Big White is a notable beneficiary late, with very strong SLRs in the mid-teens during the colder follow-on."
An active multi-wave pattern will bring on-and-off snow to the Northern Rockies through Tuesday night, with heaviest totals focused on Idaho, the Idaho Panhandle, and interior British Columbia. The initial wave is milder with elevated snow levels at times, producing denser, more supportive snow where SLRs are around 7–11:1 and concentrating accumulation Saturday night and Sunday night. Brundage stands out for totals near 13–20 inches, while RED Mountain, Schweitzer, and Jackson Hole expect around 10–15 inches. A colder transition Sunday night into Monday will lower snow levels into roughly 2,000–4,000 feet, improving SLRs commonly to 12–15:1 and enhancing snow quality; Big White and the Canadian Rockies see very strong mid‑teen SLRs. Expect periodic ridge wind, especially after the colder changeover.
