More fuel gets pumped in while your engine is cold so youll run a little richer until your engine warms up.
You're fine. If that white stuff is frozen condensation and not snow then it is super clean and you shouldn't have to worry about anything.

Yea that is really clean exhaust.
Mine is leaving a large black spot on the ground when I start it up in this cold weather, but then it has a carb and the choke stays closed for several minutes when it is this much below freezing
