My thoughts exactly J. And after 50 something winters I have noticed that I 
tend to cool off much faster when the wind is blowing as opposed to a calm 
day. Example tonight. My Blazer sat outside for 3 hours at -14F and was not 
thoroughly chilled when I went to restart it. The reason was simple, no 
wind. If the wind had been blowing strong at that temp the engine would have 
stiffened to the point of being hard to turn over after an hour or so.
The term "wind chill" actually refers to the speed of heat loss. It stands 
to reason that objects (engines, people, etc.) cool off much faster , the 
stronger the wind is blowing on them. Those of you living far enough south 
probably don't hear the term used very often but here in Sask. lately every 
weather report gives the wind chill factor. Its actually more important than 
what the ambient temperature is.
