When my furnace is running, I don't get hot water in my shower. What's going on?

This only happens during the winter when the furnace is running. It seems to be a crapshoot whether or not I'll have a cold to luke warm shower or warm shower all winter long; it's never hot. Other areas of the house also have trouble getting hot water during the winter, but it's most irritating in the shower.
The hot water heater is about 10yrs old and is inside the house in a closet with an outside facing wall. The furnace is about 20yrs old and shares a wall with the hot water heater, but is in a separate closet (the furnace was maintained this year and the plumber said it's running well and I don't need a new furnace). The both run on natural gas.
What could be causing this to happen?
