Weather
The BC/Alberta snow forecast is focused on an ongoing, high-elevation weekend storm with Banff Sunshine still open for lift-served turns through Monday, May 18. Confidence is strongest from Saturday morning, May 16, through Monday morning, May 18, when the individual models agree on the broad timing and the Canadian Rockies as the favored zone. Banff Sunshine is the practical lift-served focus, while RED Mountain, Revelstoke, Big White, Kicking Horse, Mount Norquay, and Lake Louise are closed for winter skiing, so those totals are best read as mountain weather guidance rather than lift-served expectations.
The storm is already underway and continues through Sunday before tapering to light leftovers early Monday. The individual models converge well on Saturday into Sunday timing, snow levels mostly near 1,000-1,800 meters during the snow, and modest wind impacts, but they still vary on intensity from resort to resort. Banff Sunshine is favored for 23-29 cm, with nearby Lake Louise terrain at 14-17 cm and Mount Norquay terrain at 13-16 cm. SLRs run roughly 5-14, so lower-elevation snow will be dense or wet, while the upper Rockies can see fair to locally lighter snow quality. Gusts generally look limited, mostly around 10-25 km/h where wind fields are available.
Monday afternoon through Thursday trends quieter and more springlike after the weekend system exits. The individual models mostly converge on a break with only weak, spotty precipitation chances, and they diverge on whether any midweek disturbance produces more than flurries. When snow does fall, snow levels are generally higher, so any accumulation should favor upper elevations and ski quality will lean dense. Temperatures near the snow showers range from about -4 C to 4 C, with the warmer periods likely softening exposed lower terrain.
Late Friday through the following week carries lower confidence, with the guidance spreading out on timing, intensity, snow levels, and wind. A few solutions try to reload parts of the Interior and Rockies around Monday, May 25, while others keep the pattern much lighter or mostly dry. The wetter signals keep snow levels broadly near 1,200-2,100 meters during precipitation and bring a better chance for gustier ridge winds, but the realistic takeaway is a possible modest high-elevation refresh rather than a committed larger storm at this range.
