Motorists should expect prices to start rising soon, however, GasBuddy Senior Petroleum Analyst Patrick DeHaan said. Refineries have been producing less gas, and there soon will be a seasonal rise in prices as refineries conduct maintenance and shift over to summer gasoline blends.

“Last year’s lift began the second week of February and saw the upward trend last until the beginning of May, during which the national average saw a rise of 35 cents a gallon,” DeHaan said. “This year we’re expecting a similar rise.”
