Gasoline prices, already up about 12 cents in two weeks, are expected to bubble up at least another 10 percent before peaking in the spring.
"I do suspect that March will probably deliver the largest increases," said Tom Kloza, chief oil analyst at GasBuddy. "I think they top out, and then I think they drop back."
Gasoline is averaging nearly $3.41 per gallon nationally, up 6 cents from last week, according to AAA. Kloza expects to see regular unleaded gasoline rise to $3.70 a gallon by Easter Sunday, April 20.
