Prices at the gas pump decrease, but still remain 43 cents higher than in 2010

Average retail gasoline prices in Iowa have fallen 6.3 cents per gallon in the past week, averaging $3.22 per gallon Sunday, according to IowaStateGasPrices.com.

Iowa?s pump price compares with the national average that has fallen 4.1 cents per gallon in the last week to $3.32 per gallon, according to the website.

Including the change in gas prices in Iowa during the past week, prices Sunday were 43.8 cents per gallon higher than the same day one year ago and were 17.8 cents per gallon lower than a month ago. The national average has decreased 14.4 cents per gallon during the last month and stands 46.3 cents per gallon higher than this day one year ago.

?The national average in the United States is at its lowest since Feb. 25, 2010, but remains at record highs for this time of year,? according to Patrick DeHaan, GassBuddy.com senior petroleum analyst. ?While the downtrend in gasoline prices has certainly been welcome news for motorists, I see the trend short lived and believe we may see continued volatility in the days ahead, but even with that volatility, I do expect many Americans will see average prices between $3.25-$3.50 for the rest of 2011.?
