Gas prices in Connecticut topped $4 for the second time this year, with the average gallon costing $4.03. Prices rose three cents in a week and 18 cents in a month, according ConnecticutGasPrices.com.
The national average is $3.80 a gallon, but these prices could decline soon.
"With the conclusion of the summer driving season, we can expect gasoline prices to go on a diet," said Patrick DeHaan, an analyst at GasBuddy.com, the parent company of ConnecticutGasPrices.com.
He added, "Like all diet programs, you may not see immediate loss in the short term, but we'll likely see some loss in the longer term, say the next several weeks, as factors align in motorists favor—specifically as [Hurricane] Isaac has exited without much ado, demand to see seasonal decline, and with cheaper to produce winter-spec higher RVP [Reid vapor pressure] gasoline coming, there's light at the end of the tunnel.”
