By Thursday Appleton will face arctic cold coming from the north, with temperatures way below zero degrees. This can be a very dangerous time, especially if your driving somewhere and your car breaks down. Here's a smart survival tip: have a candle and a large empty can or bottle in your car. By lighting a candle and keeping it safely contained in the can or bottle, you generate enough heat to really make a difference. If you aren't a short ways from help, it usually isn't wise to try walking anywhere in the cold. Stay put in your car until help can come.
