"The highest-confidence period supports widespread refreshes, with most mountains landing in about 4″ to 18″ by Tuesday morning and the best odds for quality turns from Sunday night into Monday. Winds look manageable in the Banff corridor but periodically strong on exposed British Columbia ridgelines, so snow quality should vary from dense to fair in the warmer interior periods to lighter snow as colder air settles in after Tuesday."
"From Tuesday through Friday, guidance converges on frequent light snowfall timing in the interior British Columbia mountains, while the Banff-area hills see lighter, more stop-and-start coverage. Revelstoke and Big White have the steadiest signal for early-cycle refreshes, generally in the 3″ to 8″ range before the weekend, while Lake Louise trends around 2″ to 6″ and Banff Sunshine or Mount Norquay closer to 0″ to 3″."
"Confidence is highest from Sunday into early Tuesday, when guidance converges on storm timing and widespread coverage but diverges on exact intensity and wind peaks by subregion. The core snowfall window is Sunday afternoon through Monday night, with a broad regional expectation of about 5″ to 12″, while favored pockets near Lake Louise and Revelstoke can push higher and RED remains the most variable at roughly 2″ to 8″."
A multi-wave weather pattern will keep British Columbia and Alberta mountains active through Tuesday morning, with a significant storm system delivering the most snow from Sunday afternoon through Monday night. Most mountains will receive 4 to 18 inches by Tuesday morning, with the best riding conditions expected Sunday night into Monday. Snow levels will range from 500 to 4,000 feet, and winds will be manageable in the Banff corridor but periodically strong on exposed BC ridgelines. From Tuesday through Friday, lighter and more intermittent snowfall is expected, with Revelstoke and Big White receiving 3 to 8 inches, Lake Louise 2 to 6 inches, and Banff-area hills 0 to 3 inches. Snow-to-liquid ratios range from 9 to 13 in the interior to 12 to 16 in Alberta, indicating varying snow density.
