How many MPG should i get for a 2003 Chevrolet Trailblazer.?

I live in the city of Pittsburgh and wondering how many miles would be normal for driving in the city? And is it much lower when driving in AWD?
Last week I had to put it in AWD to get back and forth to work due to all the snow we had and found out that I am only getting about 10 MPG.

Yes all-wheel drive reduces gas mileage. The average MPG for an '03 Trailblazer should be anywhere from 16-20 City.
