Crude oil prices are on the way up, which means gasoline prices will certainly follow. Meredith Mitts, spokeswoman for Triple-A Iowa says with colder weather ahead, refineries are starting to switch to the winter blends of fuel.

Triple-A says the cheapest gas in Iowa is being sold in Council Bluffs at two-99 a gallon, while it’s most expensive in Dubuque at three-14.
