Polar vortex presses in for the Family Day long weekend after -40 to -50 wind chills return.
The nicest day of the weekend will be Saturday as we bump up to around -13 degrees in the afternoon before daytime highs fall back into the mid-minus teens Sunday and Monday.
The mercury will plunge down toward the -30s Family Day morning with wind chills approaching extreme cold warning criteria of -40 as the core of the polar vortex, the coldest air in the Northern Hemisphere that normally sits over the North Pole, moves closer.
