Related to the weather, I follow Accuweather's Canadian weather blogger, who is a well-respected meteorologist: he often posts snow accumulation forecast maps, and his map for this event is rather interesting, showing much less in the way of accumulations for many areas than Environment Canada is saying. Only time will tell, and sometimes it doesn't take much to make a mess.

Snowfall Key:
Red: trace to 2 cm with more rain than wet snow
Gold: 2-8 cm
Green: 8-15 cm
Blue: 15-30 cm
The blue line: to the east will have a mix of snow and rain, with strictly snow to the west
