Wyoming gas prices are continuing to trend downward in advance of the Thanksgiving holiday.

GasBuddy.com senior petroleum analyst Patrick DeHaan says the average price for a gallon of regular unleaded in the Cowboy State slipped to $3.19 last week.

“Wyoming gas prices decreased by about two cents last week,” DeHaan said. “That bucks the trend of the national average, which saw prices shoot up about five cents.”

DeHaan attributes the decline in Wyoming prices to a drop in the price in crude oil from Canada.

Gas is selling for as low as $2.88 in Casper and $2.99 in Cheyenne and Laramie. DeHaan says the national average slipped to $3.26 last week.
