Anything is possible today, as far as Canada's weather is concerned, with forecasts ranging from scorching heat in some parts of the country to rain and snow in others.

Humidity and high temperatures are expected across the Great Lakes region today, with parts of southwestern Ontario expected to reach daytime highs near 31 C, with humidex values in the mid-thirties. In those parts of the province, the overnight low is only expected to drop to 21.

While southwestern Ontario is under a special weather statement for heat, northern Ontario and B.C. are under advisories for snow expected to fall later this week. Parts of northern Ontario can expect as much as 30 to 60 millimetres of rain at first, with wind gusts up to 70 km/h through Wednesday. By Thursday, areas northwest of Thunder Bay could see snow accumulation.

Snow is also expected in the mountain passes of B.C., starting Tuesday night into Wednesday morning. By Wednesday afternoon, B.C.'s mountain passes could see two to four centimetres of accumulation. Meanwhile, a reduced air quality advisory remains in place for parts of northeastern B.C., due to wildfire smoke.

Temperatures in the prairies this afternoon are trending slightly below seasonal, with frost advisories in place this morning across southern and central Alberta and southern Saskatchewan.
