First major snowfall I have noticed for the season. Not sure if it'll hang about to begin creating a base for the Colorado resorts whilst in the Canadian Prairies the temps could hit a high of 90F mark including major cities like Calgary, AB, Regina SK and possible Saskatoon! Look: http://www.accuweath...ler=0&article=1 Wednesday could see near record-tying high temperatures for Calgary, AB??? Surely a maximum temp of 33°C - (92°F) for autumn is quite remarkable now surely if not unheard of? - See below: Both AccuWeather and CBC Calgary weather forecasts the same temps as seen below!
