LOUISVILLE, Ky. (WDRB) -- You may have noticed gas prices in Louisville are up this week, but one expert said it has nothing to do with the Kentucky Derby. 

Patrick DeHaan, head of Petroleum Analysis for GasBuddy.com, said the price at the pump is up nationwide because of an increase in the price of oil, and Louisville is no different. 

"There's always the myth that gas prices go up for such an event," DeHaan said. "But when 49 of the nation's 50 states are going up, there's a lot of factors that go into gas prices."

DeHaan also said a look at the the data in Louisville shows prices tend to jump every one to one and a half weeks. He said he expects the cost of gas to peak in the next few weeks, hovering right around the $3 per gallon mark.

But he expects the price to come back down after Memorial Day.
