According to Patrick De Haan, head of petroleum analysis at GasBuddy, cold weather is impacting prices at the pump.

“The Arctic weather impacted refineries in the Rocky Mountains,” De Haan said. “In fact, it shut those refineries down for a longer period of time in Colorado, and Colorado was seeing gas prices shoot up 90 cents a gallon because of that refinery primarily serving Colorado. Now gasoline has to be brought in from neighboring refineries.”
