You probably won't be getting much snow tonight so I wouldn't worry about it for now, anyway. With off road/snow tires, you're probably not going to even notice a difference driving in the snow to a normal road! It's only really with all-season/worn out tires that snow driving is really treacherous. Before I got winter-specific tires, I'd have trouble driving up steep hills in the snow (I live in the Berkshire hilltowns when I'm home)--like with sliding/spinning tires.

I got snow tires for last winter and I didn't have ONE slide. Of course, last winter was pretty wimpy... I like my dad's plan--if it's a blizzard outside, just don't drive in it!

Drive slow in the snow, don't make sharp jerks of the wheel, and if you start to slide, gently turn your wheel in the opposite direction of the slide, to even yourself out.

At least, that's the way I learned it! Haven't had a crash yet!
