Markham, ON - Further loads on schoolwork (exams, etc) had prevented me to go in-depth of weather in other parts of Canada. For the next 2 weeks, my weather blog will only cover MAJOR weather stories, as I cannot spare as much time as I used to be.

Today's Weather Equation = Edmonton's Cold Temperature + Stephenville's Sea Effect Snow + St. John's Winds

The answer should come up pretty obvious as Southern Ontario and Québec's Cold Wave. After a long "heat wave" last week, that melt majority of the snow, it's time for the cold air to return. A departed Alberta Clipper had dragged down the nasty cold air that settled around Edmonton, Alberta for days before. The Clipper drew the line that divided the cold and the warmth. That stationery front passed through us late last night. With some heavy bursts of snow to go with that, Arctic Air quickly settled in. In order to "kick" the warmth out, strong northwesterly winds resulted. Gusts of over 100 km/h blown around the GTA, while significantly less in the city. The water (the water originated from the wet snow on the previous night and from the meltwater of previous snowfall accumulations) on roads had quickly turned into ice. This had caused significant traffic problems, especially outside the city (Toronto), where the temperature is even cooler. The wind plus the cold temperature combined created wind chill values lower than -10 C.

Although temperature is still falling, winds had start dying down a bit and the wind direction had switched. The temperature is expected to fall much of tomorrow, and continue to fall throughout Sunday, towards a nighttime low of -14 C during Sunday-Monday overnight periods. Temperature are expected to stay at least 3 degrees Celsius below seasonal value (Seasonal value is -2 C). Next week is even looking grimmer, which will be covered on tomorrow's blog.
