they're just a scam by the grocery companies to sell more groceries. 
Oh hey, let's pay the NWS to put up a few winter storm warnings, that should scare people into buying a few hundred dollars worth of groceries and causing major traffic jams on every major road within a few hours. Yay!
I swear it's been the same damn storm that was supposed to have happened for the last week and it hasn't happened yet, or if it has, then it's one damn wimpy storm. I can still drive, that tells you something right there. They're considering light snows and half a millimeter of ice to be winter storms these days.
