1 day ago Bob Ambrose Merry Christmas! We’ll have a weak ridge of high-pressure building over the Alberta Rockies on Christmas Day and Boxing Day. By Fri, an upper trough brings back isolated flurries and light amounts at resorts along the Divide (Castle, Sunshine, Lake Louise, Marmot Basin). Weak disturbances will bring even more light accumulations on Sat through Mon. Beyond that, next week is now trending drier.
