Winter storms are predicted to have a substantial impact on gas prices in the Upper Midwest, according to recent reports from sources like USA Today and AAA Auto Club. Heavy snowfall is anticipated across Minnesota, Wisconsin, and Michigan, following a period of warmer temperatures on the East Coast. The national average gas price has already increased to $3.63 per gallon, up from $3.32 the previous week, primarily due to geopolitical tensions, including U.S. strikes on Iran and potential disruptions in the Strait of Hormuz. These tensions are now expected to be compounded by the impending winter storms.
