Winter-like conditions are expected to return to Toronto Tuesday with sub-zero temperatures, ice pellets and even some light snow flurries possible.
Monday afternoon's forecast high of 19 C with rain will give way to a sharp drop in temperatures overnight.
CBC meteorologist Jay Scotland said temperatures will likely hover around or below the freezing mark on Tuesday.
"We're looking at the bigger shock really coming through overnight tonight and into tomorrow morning with the passage of a very sharp cold front that will see temperatures not only dropping, but plummeting below the freezing mark.
"Early Tuesday morning we'll see that rain transitioning back to snow and there is the risk of some freezing rain heading into the morning commute."
A special weather statement from Environment Canada warns that a few centimetres of snow are possible in some regions of the Greater Toronto Area by Tuesday afternoon.
"Motorists should be prepared for a quick return to winter driving conditions, especially in areas that receive a period of heavier snow," reads the Environment Canada statement. "Untreated roads and surfaces may quickly become partially to mostly snow covered and slippery."
The cold temperatures come after last weekend's sunny weather with daytime highs in the 20 C range.
Conditions won't improve much on Wednesday or Thursday, where daytime highs are expected to remain in the single digits until at least the weekend.Suggest a correction
