There might not be any perfect chase based on winds, temperatures, or deepness. The deepest totals will fall in the central and northern Sierras, followed by south coastal BC near Whistler. Wind and temperature swings could cause issues. The North Rockies look better for less wind and colder temps with 8-16 inches.

Increasing cloud cover on Friday ahead of a Pacific storm system that now looks to just barely brush the Alberta Rockies this weekend. Trace accumulations up to 5 cm are slightly possible each day at Sunshine, Louise, and Castle. Another weak pulse of moisture next Wednesday returns chances of light accumulations. Colder on Mon and Tues, SW flow on Weds brings the snow, along with warmer temps.

A storm remains on track for the West from Friday to Sunday with the deepest snow totals favoring the Sierra, Cascades, BC Coast Range, and Northern Rockies. A weaker storm will move across the West early next week, followed by a warming/drying trend through Christmas. The East will see a mild pattern with more rain than snow through early next week, followed by a colder pattern late next week.
