“The national average saw a modest increase over the last week after storms temporarily knocked the Midwest’s largest refinery offline in Indiana, triggering sharp jumps in gas prices across Ohio, Wisconsin, and Michigan,” said Patrick De Haan, head of petroleum analysis at GasBuddy. “We could soon see prices cycle higher in Illinois and Indiana as well, although there’s been some late-week relief in wholesale prices now that the refinery is restarting. Meanwhile, Florida saw the nation’s largest weekly decline, but a rebound due to price cycling is likely on the horizon. All of this is playing out while oil prices remain relatively stable in the low $60s. With no major hurricanes threatening the U.S. at the moment, the biggest wildcard remains any shifts in Russia’s war on Ukraine. For now, expect only moderate gas price fluctuations, with the potential for lower prices arriving later this fall.”
