Some areas of the GTA experienced a high of 18 C by midday, a seasonal record for the date.
Later in the day, however, the warm air will give way to an Arctic front that Environment Canada says “will blast across the regions” and be “heralded by strong and gusty” winds.
In a special weather statement issued shortly after noon Tuesday, the weather agency says that gusts of up to 80 km/h are possible, with some areas seeing wind upwards of 90 km/h.
The statement warns the winds could cause serious problems for drivers, especially on exposed stretches of highways that are “subject to strong cross winds.”
To add insult to injury, the temperature will fall drastically to just below freezing by tonight. The colder temperatures could usher in lake effect snowfall in areas east of the Great Lakes, the statement said.
