Gas prices throughout Wyoming continue to decline.

That’s the good news. The bad news? Don’t expect the decline to continue into January and February.

The average price for a gallon of regular unleaded in Wyoming has dropped to $2.97 a gallon.

However, Patrick DeHaan, a senior petroleum analyst with, says he expects prices to begin to rise again toward the end of 2012 and the start of 2013.

“Low gasoline demand is what’s bringing prices down, DeHaan said. “But we tend to see some year-end inventory movement that tends to put upward pressure on prices, and that’s why we believe prices will start to move higher.”

“But, a lot of that is supply and demand, and the retail shopping holiday will play into this as well,” DeHaan said.

Laramie and Casper have the state’s lowest gas prices, with multiple stations selling regular unleaded gas for $2.69 a gallon. One station in Laramie is selling regular unleaded for $2.61 a gallon.

The national average for a gallon of regular unleaded is $3.25.
