Your mileage will drop in the winter (warming up, spinning at slippery intersections, etc). I would say it's normal, depending on your driving habits. The only thing I would do is look at a tuneup for your vehicle if it hasn't been done recently...nothing worse than your car breaking down when the wind is blowing and it's 30 below.
Don't feel too bad about your mileage...my pickup gets about 20 mpg on the highway and 13 in town. I gotta have my 4x4.
