Yes, it does, but so do many other factors.  Besides, those of us who
live in the colder areas (Minneapolis/St. Paul is warm for me) pretty
much ignore the wind-chill numbers anyways.  (Except for impressing
our friends from down south.  Personally, I find it much more
impressive to say that if the air temperature is, say, -20 deg F so I
can warm up by going into a freezer.)  What factors do I use?  More or
less in order:

	- how long I am going to be outside, and where I'm going
	(putting out the garbage doesn't even rate a coat, regardless
	of temperature)
	- air temperature
	- amount of sun
	- type and amount of snowfall
	- wind speed, direction, gustiness, etc.
	- humidity (usually about 50% which equates to 5% or so when
	the air is warmed up)
