According to The Weather Network, a Colorado low, a polar vortex and lake-effect snow are aimed to hit the province this month.

Due to the Colorado low, widespread snow and gusty winds will push into Ontario by Thursday evening, with 5 to 10 centimetres expected throughout the southern part of the province. 

However, areas up north are expected to see up to 30 centimetres of accumulation. 

This weekend, the polar vortex is also expected to hit with chilling temperatures. 

Parts of Ontario could feel as cold as -16 C by Saturday. 

On top of this, lake-effect squalls are expected to last until next Friday, so make sure to bundle up. 

Environment Canada issued a travel advisory this morning, warning drivers of poor road conditions.

"Untreated roads may suddenly become snow covered and slippery. Motorists should allow for extra time to reach their destination," the agency states.
