Environment Canada has issued a special weather statement for much of southern Ontario, including Toronto and the GTA, calling for “some un-Christmas-like weather for the first few days of winter.”
The statement extends to parts of eastern Ontario as well, including Kingston and Ottawa.
Winter officially arrived at 6:03 p.m. on Sunday, but milder weather is expected to move into the region over the next couple of days.
A low pressure system over the U.S. Midwest will track towards the Great Lakes, bringing some rain on Tuesday, the weather agency says.
680News meteorologist Jill Taylor says it will be mainly cloudy on Monday and a high of 3 C. On Tuesday, the forecast calls for rain in the late afternoon or evening and a gusty wind, with a high of 5 C.
Parts of Eastern Ontario could encounter freezing rain before warmer temperatures arrive later on Tuesday, the weather agency says.
White Christmas not likely
According to Environment Canada, rain is expected to continue into Christmas, with the temperature forecasted to hit the single digits and potentially the low teens in many areas.
Taylor says rain will be heavy at times on Christmas Eve, with around 15-20 millimetres in accumulation, a gusty wind to 50 km/h and a high near 10 C. Rain is expected to change to snow overnight as the temperature drops to 2 C.
As for Christmas Day, some areas could see some light flurries accompanied by a strong wind. Although the temperatures will be cooler, the weather agency says “don’t expect much if any accumulation for a white Christmas.”
Taylor says the GTA will deal with windy conditions and wet snow on Christmas Day. The high will be near 2 C but will feel like -8 C with the wind.
