This compares with the national average that has increased 5.7 cents per gallon in the last week to $2.86/g, according to gasoline price website GasBuddy.com.
AAA Oklahoma Spokesperson Leslie Gamble attributes the increase to supply and demand as well as the White House's decision to re-impose sanctions on Iran. In the summer of 2014, the average price rose above $3 a gallon, just before OPEC increased production in an unsuccessful effort to drive US shale producers out of business. He also believes that there is a high possibility that crude oil prices will continue to rise and gas prices may reach as high as $3.
Gas prices have been consistently high for three weeks straight, with a national price average of $2.87.
Sticker shock at the gas pump has been most severe for motorists in OH, where the average price shot up by 15 cents a gallon. Gas prices have gone up 19.8 cents from last month's average and have increased 53.3 cents from last year's average. North Carolina's average falls below that level, at $2.71 per gallon.
Analysts say the gas prices nationwide are close to hitting $3 per gallon for the first time since 2014, when it averaged $3.62.
"U.S. supplies are down a little", Williams said.
Nationally, 36 states are seeing gas prices that are a nickel or more expensive than the previous week.
In addition to the summer blend of gas costing more to produce, Williams says economic pressures at home and political uncertainty in the Middle East are driving the prices up.
