The MétéoMédia – Cross-country ski mower delivers first snow delivery to the Prairies
Monday, November 8, 2021, 8:30 p.m. – A system that begins in the West will eventually cross the country this week, first bringing cold temperatures, snow and strong winds to the Prairies.
An Alberta mower soon to bear fruit will make a trip across the country, eventually merging with a Texas low, making a few stops in the snow along the way – looking to the Prairies as its first destination. The system will be comprised of energy from a “weather bomb” that is currently affecting British Columbia. The energy will spill over the Rockies, stirring a snow-capped Alberta mower by Wednesday morning. The region can expect to see considerable snowfall in a strip of northern, central and southern areas of all of the Prairie Provinces, as well as a gust of strong winds that can occasionally result in whiteout conditions. Travel impacts are expected, particularly along the Trans-Canada Highway. More information on when the snow and winds are happening, and what to expect, below.

Widespread winds of 60 to 70 km / h on Wednesday afternoon will be felt in southern Alberta and Saskatchewan, and Manitoba in the evening as the clipper approaches.
Whiteout conditions will be possible, so motorists should be careful before setting off on the roads. Significant impacts on travel are expected along the Trans-Canada Highway.
