“The national average price of gasoline edged higher last week, with the vast majority of states seeing prices climb,” Patrick De Haan, head of petroleum analysis at GasBuddy, which provides real-time gas price information from more than 150,000 stations, said in a statement released Monday.

“Refinery issues in the Great Lakes and West Coast have kept prices elevated, and gasoline inventory data from the government showed another large weekly drop in supplies, which has temporarily propped up prices.

“With thousands of flight cancellations ahead of Thanksgiving due to the FAA flight cuts, there could be slight shifts in gasoline demand, which may limit any near-term declines.”
