People of Seattle,
Chill the fuck out. There is a possibility of "a few snow showers." You all are acting like Armegeddon is imminent. It's a little snow. Maybe. Just don't do any unnecessary driving on hills. You'll be fine.
You may also be concerned because it is supposed to get cold. By which I mean Seattle-cold. Yes, it will go below freezing. There may be a 24 hour period where it stays below freezing. You'll be okay. Just shelve those flip flops and your lightweight fleece and put on some socks and a coat.
You will survive this. I have faith in you.
