CASPER, Wyoming — Gas prices are back on the rise in Wyoming, though not by as much as prices nationwide.
Average prices in Wyoming this week are up 7 cents a gallon to $2.18. That's compared to a 14-cent increase nationwide to $2.44.
Over the past month, gas prices nationwide are up 39 cents a gallon. Wyoming's gas prices increased by only one-third as much as that over the past month.
The Casper Star-Tribune reports (http://bit.ly/1zFfhET ) oil prices are around $50 a barrel, or roughly half the price a year ago. Oil prices account for more than half of the price of a gallon of gas.
Analysts attribute rising gas prices to a switch to summer gasoline blends, reduced output from refineries due to maintenance and a United Steelworkers Union strike.
