The week may be off to a warm start, but the nice weather won’t be sticking around, with up to 15 cm of snow coming later this week.

Environment Canada issued a special weather warning for Toronto saying freezing rain and snow is expected throughout Wednesday, beginning in the early morning.

“The precipitation may begin as snow then change to rain or freezing rain or continue as snow,” the agency wrote in their alert. “Total snowfall amounts of 5-to-15 cm are possible in areas where the precipitation falls primarily as snow.”

Temperatures will remain mild Tuesday and Wednesday afternoons, and drop just below zero both evenings. Temperatures will then drop to -6°C Thursday night, and to -11°C on Friday night, with a high chance of flurries both nights.

Where the snow and rain will hit Wednesday remains to be seen, however.

“There is much uncertainty regarding the track of this low. Any change in the track could drastically change snowfall amounts and precipitation types,” Environment Canada wrote.
