Gas prices in Wyoming are beginning to slide.

GasBuddy.com senior petroleum analyst Patrick DeHaan said the average price for a gallon of regular in the Cowboy State fell nearly three cents last week to $3.59.

“What we’re seeing nationally is prices declining about 3.5 cents per gallon,” DeHaan said on Monday. “Decreases are here, and they’re set to come around the country.”

DeHaan also said price declines in Wyoming can be expected for the next several weeks.

“Oil prices have given up significant gains lately, dropping from $107 to $100 per barrel,” DeHaan said. “With the way things are shaping up, we could see a couple weeks of relief at the pump.”

Gas is selling for $3.40 in Casper, $3.45 in Cheyenne and $3.39 in Laramie. The national average is $3.61, DeHaan said.
