The Greater Toronto Area and much of southern Ontario will experience a mix of messy winter weather after a spring respite.

A snowfall warning is currently in effect from Environment Canada for the City of Toronto and many surrounding areas.

According to the agency, the city could see up to 15 to 25 mm of rain from Wednesday evening to Thursday evening, followed by an accumulation of 10 to 20 cm from Thursday afternoon to Friday morning.

“A low pressure system is expected to track northeast across Lake Erie and Lake Ontario on Thursday evening bringing a disorderly mix of winter precipitation to southern Ontario,” Environment Canada wrote in its warning. “Precipitation will begin as rain this evening and change to snow Thursday afternoon. Freezing rain and ice pellets are also possible Thursday morning and afternoon. »

Snow warnings are also in effect for York, Durham and Peel regions, as well as most parts of southern Ontario from Cornwall to Windsor.

Environment Canada noted that the timing and amount of precipitation could change as the exact path of the system remains uncertain.

“Be prepared to adapt your driving to changing road conditions,” the agency warned. “The rapid accumulation of snow could make travel difficult in some places. Visibility can sometimes be suddenly reduced in heavy snow. Surfaces such as highways, roads, sidewalks and parking lots can become difficult to navigate due to snow accumulation.

CP24 meteorologist Chris Potter said commuters should be ready to transition from “spring into winter in a few hours tomorrow”.

“Spring-like conditions here, at least for now through overnight and early tomorrow morning, and then winter makes a big comeback as we get colder,” Potter said.

He said morning and evening runs would likely be affected by bad weather.

“The morning first will obviously be impacted by the potential for buildup, cooling, hydroplaning, slightly reduced visibility and precipitation,” Potter said. “But then in the afternoon and evening, icy and slippery roads are expected as we obviously go from hot to cold.

“So any lingering water, standing water could freeze over and of course the added non-benefit, if you will, of freezing rain and ice pellets across the lower Great Lakes, including the GTA.”

After weeks of freezing temperatures, the city experienced an unusual high of 9C on Wednesday.

A high of 6°C is expected on Thursday morning, but the temperature is expected to drop in the afternoon, dropping to a low of -11°C.

In A press release On Wednesday, the City of Toronto said “winter crews and equipment are ready to respond” to the inclement weather.

“The city has a comprehensive snow and ice response plan with operations focused on the safety and flow of residents and emergency vehicles with the salting and snow removal of roads, sidewalks and bike paths” , the city said in its statement.

The city said it would provide an update on its efforts Thursday and advised drivers to be extra careful on the roads.
