“As the national average for retail gas prices appeared to be headed for a week over week decrease, prices popped back up thanks to a late-week surge by Great Lake states,” said Will Speer, senior petroleum analyst with GasBuddy.com. “While pockets of significant gas price hikes were prevalent, especially in regions such as the Pacific Northwest and Rockies, 22 states actually had prices decrease. So, as states struggled to agree on the movement of gas prices, the national average barely moved as a result, only increasing a penny per gallon in one week’s time. With the Memorial Day holiday two weeks away, it marks the kickoff to the summer driving season. Gasoline demand that has already been strong this year will undoubtedly see a huge seasonal increase in demand. This paired with crude prices that continue to show signs of strength are going to keep further pressure on gas prices this summer.”
