The temperature in Toronto edged past a record high mid-morning on Tuesday, exceeding 16 Celsius.

Environment Canada reported the temperature at Toronto's Pearson International Airport was at 16.2 C, shortly before 10 a.m.

The forecast had called for a high of 13 C, falling to 8 C by the afternoon.

That would have been an unseasonably warm high for Dec. 4, when temperatures in the city have historically averaged around 4 C.

The previous record high of 15.9 C was set in 1998. At the other end of the scale, the coldest Dec. 4 on record was in 1940.

The temperature plunged to -25 C that day, which also goes down as the snowiest Dec. 4, with a total snowfall of 7.1 centimetres.

According to Environment Canada, this latest warm spell will be short-lived, as the agency’s forecast calls for the thermometer to dip overnight with an expected high of just 2 C Wednesday.
