Does the cold weather give such a poor gas mileage?

Colder weather my give you better performance because of the denser air, but with that denser air comes more fuel going into the combustion chamber. End result being that colder weather certainly does not give better economy.

I used to get about 350 miles with full tank, but it dropped down to 200 miles now. Is this because of the low temp?
Also, I remember seeing a thread saying that warming up our ISX50 before on the go is not good for the engine. Would that theory apply even at this cold weather?
Thanks in advance

I'm down to 15 mpg in the city. I think that when it's icy or snowy out the car loses traction more, so that's wasteful. Also, I think I tend to brake more which for sure is not helping my mileage. I drove on the freeway yesterday and was able to bump my average mpg to 21.5! First time in months I've been over 18 mpg..
