Perfect weather in Montreal - snow in Calgary

Crazy summer snow in Calgary on Monday as between 10-20cm of wet snow fell. More is forecast Tuesday night before a warming trend arrives. (The National Post).

While it was 25C (77F) with bright sunshine in Montreal on Monday, snow was falling across central and southern Alberta. Southern Quebec had a nearly perfect weather day, moderate temperatures, low humidity and bright sunshine. It was clear and calm overnight for viewing the full harvest moon, a super moon at that. The weather will hold today as high pressure crests over the region. Temperatures will once again warm to 25C. Clouds will begin to move into the region on Wednesday as a cold front approaches from the west. It will be windy with a steady rain and much cooler temperatures on Thursday, 18C (65F) before an October like air mass arrives for Friday into the weekend. Temperatures on the weekend will be down to 5 to 8C at night and only 16 to 18C during the day.

That same front produced a breezy, unseasonably cold day with snow on Monday in Alberta. Accumulations of 20cm was reported in northwest Calgary, 18cm fell at Bow Valley,  9cm at the airport in Calgary, while Edmonton had 2cm. Frost and cold temperatures followed the snow with Calagry at -1 (30F) this morning. Another Pacific front will bring more snow tonight across the foothills of Alberta. Environment Canada has posted another snowfall warning for the city of Calgary with a forecast 10-15cm possible from late Tuesday into Wednesday morning. Temperatures will range from -1 to 3C. A big warm up is forecast by the weekend with highs near 24C (76F) by Saturday!
