Average retail gasoline prices in Iowa have risen 5.1 cents per gallon in the past week, averaging $3.07 a gallon on Sunday, according to GasBuddy's daily survey of 2,036 gas outlets in Iowa.
Including the change in gas prices in Iowa during the past week, prices Sunday were 19.0 cents per gallon lower than the same day one year ago and are 20.0 cents per gallon lower than a month ago.
Average retail gasoline prices in Missouri have risen 8.5 cents per gallon in the past week, averaging $2.90 a gallon on Sunday. That is 18.4 cents per gallon lower than the same day one year ago and 17.3 cents per gallon lower than a month ago.
The national average has increased 1.6 cents per gallon in the last week to $3.21 per gallon.
"Surprisingly, the decreases we've seen in the national average have all but dried up," said GasBuddy.com Senior Petroleum Analyst Patrick DeHaan. "I admit, it's a bit of a head scratcher to have seen wholesale gasoline prices perk up last week, and it's a bit premature to say we've seen the end of decreases in gas prices for the time being, so I'm hopeful that an uptick in the national average is merely temporary, but then again, this year has featured trends in prices that have all been earlier than expected," DeHaan said.(Information provided by GasBuddy.com)
