Hitting cleared asphalt definitely throws a wrench into the monkey works. Changing surfaces is the "fun" part, which is what winter driving is at it's core. Guessing where the traction is.

Best advice I can give on snow is that every input you make is either horribly exaggerated (locked/spinning wheels, huge oversteer) or completely ignored (terrible understeer). Give yourself plenty of time/space to do whatever it is you're trying to do.
