Not sure how cold it is where you are, but that's pretty typical. There are a lot of factors that reduce economy in cold weather:
- cold engine
- cold transmission and differentials
- higher air density increasing aero drag
- higher air density increasing engine pumping losses.
- spinning on slick surfaces, or slow traffic on slick surfaces

A block heater helps quite a lot for shorter trips. Grill blocks will help a bit too.
