Summary

A wide trough of low-pressure that’s been draped across Western Canada for the last several days will allow a Pacific storm system to move just south of the border on Fri bringing snowfall in the 10-15cm range to Castle Mtn with lighter accumulations to 5cm possible as far north as Banff/Sunshine. High-pressure builds Sunday before a SW flow transports a more potent Pacific storm Mon thru Weds.
