How cold is cold?

I slept like a queen last night - but more of that later...

How cold is cold? Oh my word the wind was howling all night long (and still is at this very moment. My husband got the call that the base is closed today because of the extreme temperature drop. Currently as I write it's -10 degrees and folks that without the wind-chill...with the wind-chill it's a whopping -42 degrees. This is horribly cold weather and we have all been advised not to travel, heck not to even venture out of doors.

I'll write more on this situation as the day progresses.
