Did you know that to have a white Christmas in Toronto, certain conditions have to be met before it can officially go down in the history books as a white Christmas? Check out the article below...
A white Christmas is declared if there is 2 cm of natural snow on the ground at 7 a.m. on Dec. 25. "Most people aren't aware there is a very specific definition," Environment Canada senior climatologist David Phillips said. "You can't just measure the piles of snow near the side of the road. To be safe, walk to the middle of your backyard and take the measurement there first thing in the morning." If the snow isn't there at 7 a.m., but comes later in the day, it is not an official white Christmas, he said.
In recent years, there's only been a one-in-three chance Toronto has seen enough snowfall to make the call. The expanding "urban island" -- pavement and buildings that melt the snow -- combined with global warming and natural weather cycles has warmed up the city. "Sometimes you'll have snow in the suburbs but none in the downtown core," Phillips said. "This year we should see snow throughout the GTA on Christmas."
Warmer weather is on the way, but it won't be enough to melt away our chances of a white Christmas.
