And now comes the Cold as Environment Canada notes of an Arctic Outflow Warning for North Coast, coastal sections

Just in time for Christas Eve and Day the Northwest gets 
a taste of the Deep Freeze

Now that we've settled into a shovelling groove, a new curve comes our way with Environment Canada issuing an Arctic Outflow Warning at 3:49 PM Thursday for the North Coastal Sections and points inland.

Wind Chills bring the temperature towards Minus 20 as the Arctic air strengthens Friday, resulting in temperatures falling further and northeast outflow winds increasing to 80 km/h gusting to 100 especially through mainland inlets and valleys along the coast. 

Wind chill values below minus 20 will expand to the north and central coasts Friday night. 

However, for north coast inland regions, wind chill values will dip as low as minus 30.
