As I opined in Wednesday's post, cold and snow is coming to western Canada. Brett A. at Accuweather beat me to a detailed posting... I was/am going to post the same picture as he. Here is the GFS Ensemble temperature departures from normal (degree F) over the next week. But I'll go one further, showing the week two temperatures departures courtesy of Weatherbell which shows it still cold in the west but spreading east.
