Overnight gas prices went up again.

Average retail gasoline prices in Cleveland have not moved  in the past week, averaging $3.75/g Sunday. This compares with the national average that has increased 5.2 cents per gallon in the last week to $3.71/g, according to gasoline price website ClevelandGasPrices.com.

Including the change in gas prices in Cleveland during the past week, prices Sunday were 27.4 cents per gallon higher than the same day one year ago and are 29.3 cents per gallon higher than a month ago. The national average has increased 27.8 cents per gallon during the last month and stands 24.1 cents per gallon higher than this day one year ago.

"Gasoline prices have spiked considerably higher in virtually every area over the last two weeks, and while I don't expect the pace of the recent rise in prices to continue for the entire month, a similar jump may again occur closer to April Fools Day, and it won't be a funny joke, it'll be disgusting reality," said GasBuddy.com Senior Petroleum Analyst Patrick DeHaan. "The rise in price is so unbelievable that we may have to revise upward our previous gasoline forecast that had called for a national average of between $3.75 to $4.15 by mid-May, as the national average already stands at nearly $3.72/gallon," DeHaan said.
