We in Alberta are in the middle of another Polar Vortex. Here are today and tonight's temperatures in Fahrenheit.

Now (10:50 a.m.) -25°F Wind Chill -33

Tonight: Low minus 41. Wind chill minus 39 this evening and minus 47 overnight. Frostbite in minutes. (This is also in degrees F)

Thursday isn't much better - that's when a bunch of us carriers deliver the local newspaper. I invested in boots that are waterproof and rated to -40 (same temp on both scales).

YIKES!
