Will Ottawa have a green Christmas?

Trashy posted something a couple of days ago stating unequivocably that “no way… is Ottawa getting snow before Christmas day”. The long range forecast on Environment Canada’s website suggests it’s going to be cold enough for snow and the latest aviation forecast suggests there’s going to be periods of snow overnight::

For those who need a translation, it basically says starting at 4pm this evening (2100Z), there will periods of light rain showers and light snow showers until 10pm followed by periods of light snow showers until 5am tomorrow morning. I suppose there could be a thin layer of snow that hangs around until Christmas but I’m not too hopeful. If you believe the long range forecast, there will be periods of snow on Christmas Day, but it’s still a bit early to tell for certain.
