Discussion
A widespread winter storm will move into the region this afternoon and continue through most of the day Saturday. Avoid travelling this weekend if possible as conditions will deteriorate.
Areas along the shores of Lake Erie and Lake Ontario are expected to see snow to start but transition to a mix of rain and snow, then to straight rain, reducing snow totals. Areas north will see only snow. During the beginning of the storm, heavy snow is expected, which may bring in enough energy to create thundersnow across the region. Wind gusts of 80 to 90 km/h are expected today and will likely continue into Sunday for many areas. Whiteout conditions will be possible across the region, as well as blowing and drifting snow. Power outages will be possible.
Snow will move back into Southwestern Ontario tomorrow as cold air wraps around the low pressure system, also bringing cold arctic air as temperatures drop through the day on Saturday. System snow will begin moving out of the area late Saturday. Temperatures are expected to drop fairly quickly during the day on Saturday. Any wet roads are expected to freeze and become icy quickly. A flash freeze event will be possible.
Late Saturday into Sunday, some lake effect snow is expected to develop for the snowbelts. Southwestern Ontario is expected to see lake effect snow from Lake Michigan. An additional Snow Squall forecast will be posted tomorrow.
