Wind Chill

Another weather-related fallacy:  Wind Chill.

"Today it the temperature will be 10 degrees but the wind chill will make it feel like -5"

Wind Chill is NOT how it will "feel" - it is a model of how fast your skin may cool down towards the actual temperature.  It is a model that makes a whole LOT of assumptions (most of which are probably untrue as you go out into a cold, windy day).  Slate.com has a good article about this here

This is like saying you may overshoot your destination today because the traffic is bad.  Stick the facts please:  just tell us the temperature and the wind speed.
