A benign weather pattern will hold over the region for the next few days. As a trough moves from BC into Alberta, clouds will develop and a trace to 5cm of snow is expected by Wednesday morning. Winds may increase to the moderate range Wednesday, but remain light on Tuesday. Temps will be seasonal with freezing levels below surface.
