Prepare for poor driving conditions, snow squall warnings continue in southern Manitoba

Wednesday, October 23, 2013, 9:17 AM -

Lake-effect snow squalls dumped up to 20 cm of fresh snow in some areas of southern Manitoba Monday night.

Snow squall warnings remain in place for some areas, with the potential for another 15 cm of snow to fall through through Thursday.

"The heaviest squalls are expected through the Lake Winnipeg narrows region where 15-25 cm of snow is possible by Thursday morning including over Hecla Island," says Environment Canada's warning statement.

EC adds that weaker bands of lake effect flurries are also likely to the southeast of Lake Manitoba on Wednesday, however warning amounts of snow are not likely.

According to Weather Network meteorologist Gina Ressler, late October into November is the prime time for lake-effect snow in southern Manitoba.

"Manitoba lakes are currently running at about 8°C, which is much warmer than the cold air mass situated over Manitoba this week. The temperature difference between the water and the air aloft creates a layer of instability, and if the winds align in the right way, lake effect snow squalls can develop downstream," Ressler explains.

Drivers are urged to take extra precaution as snow squalls can reduce visibility significantly.
