GLOBAL WARMING: Calgary is stunned by SNOWFALL in the middle of summer

For most people, seeing snow falling in the middle of summer might come as a bit of a surprise. But not for the residents of Calgary, who happily watched the white stuff falling all of yesterday and barely batted an eyelid. In one video uploded to Twitter, snow can be seen falling in a supermarket car park while a woman in the background says: 'Only in Alberta, eh?' Another image shows two men in their boxer shorts holding a Canadian flag in the woods in Banff where at least a couple of inches of snow has built up.One person managed to capture an image of frosty flakes covering a summer flower, while others took pictures of their uncovered patio furniture disappearing under a blanket of white. Meanwhile Twitter user Alison Wong wrote: 'Calgary, my beautiful hometown, where I've now officially seen snow in every single month of the year.' Forecasters had predicted rain all day on Friday with a high temperature of 46F (8C), but as the temperature took a tumble, the rain turned to snow.  While the heaviest flurries took place across the Rockies, particularly in Banff, but by early afternoon it had begun snowing across lower ground, including in Calgary. By the following day, however, things returned to normal with a full day of sunshine, though temperatures were still a little low at 60F (15C). The forecast for the rest of the week shows the area staying sunny, with temperatures pushing up to a slightly more summery 80F (26C).
