Calgary's forecast: Brief return to cool weather before it's cold again

The main notes of the forecast are relatively simple for the next five days.

Stay inside. Do the level best that you can to stay out of this cold. An extreme cold warning exists for all but four regions of Alberta this hour.

We get some sense of reprieve a day from now, where a number of southern Alberta's warnings will likely fall away. That doesn't mean the temperatures are improving, much; the polar vortex will continue undulating, and our weekend will see a brief westerly wind before another plunge into more snow next week.
