'Polar vortex' to blast frigid air over much of US

[dixiegrrrrl]

40. I used to go into the store walk in freezer to get warm!

I worked at our local co-op and one winter we had a prolonged freezing spell of around 15 at night,
in the Pac. Northwest.
I had to open the store at 7 am, fire up the wood stove, set out the produce, etc.
The walk in freezer was warmer than the store in the am.
That kind of cold weather was bearable, because the humidity was low.
I found that on this side of the Rockies, the humidity makes the cold much worse, right to the bone.
