"Ten Degrees and Getting Colder (Down by Boulder Dam that Day)"

Wheeeeee!

That's -17°C / feels like -23°C, for you European folks.

(The alarming fine print on that "Wind Chill Warning" reads, in part: 

A wind chill warning is issued when winds combine with bitterly
cold temperatures to create extremely dangerous conditions for
exposed skin.  The wind chill will be cold enough to cause
frostbite in about 15 minutes or less...and could lead to
hypothermia if proper precautions are not taken. If you must go
outside...remember that several layers of clothing will keep you
warmer than a single heavy coat. It is very important to cover
all exposed flesh to protect yourself from frostbite.

But I walked home in it, and it didn't seem that bad!)
