Winter weather advisory

I love the term "Winter weather". What does that entail? Ice? Snow? Sleet? Extreme cold temps? Shelby Co. is under one of these advisories but I'm not buying it. I went to the dry cleaners today in a mere light cotton cardigan and the weather was rather mild, and yet our county is lit up in white on the TV screen. *sigh* I'll believe it when I see it.
