How old are your O2 sensors and have you looked at your MAF sensor? O2 sensors wear out over time and if they are the OGs, they are due for a change (mine are due as well). If the Mass Air Flow sensor is dirty, it will effect fuel trims as well.
As mentioned above, the winter fuel will cause a drop in mpg and the longer time it takes to warm up to operating temperature will do the same. Up until the engine reaches a certain temperature, the fuel trim will be running rich to speed up the warm up time.
Check your tires too. Every 10 degrees of temperature change equals 1 psi of tire pressure change, plus tires lose air pressure over time anyway. Even new tires on new rims.
