The American Automobile Association has announced that gas prices were steadily moving on a downward path, but tensions with Syria caused oil prices to jump and in turn pushed gas prices up a few cents.Although gas prices are more than last week, overall they still remain about 20 to 25 cents less than last year's averages for the Labor Day weekend say AAA officials.Last year, motorists paid an average of $3.83 nationwide for a gallon of regular gasoline throughout the Labor Day holiday. This year, a gallon of gas averaged $3.59 during the holiday weekend. Although concerns about the U.S. performing airstrikes against Syria caused oil prices to reach upwards of $112 a barrel last week, prices soon decreased after a lack of global support for attacks on the country."Since U.S. threats against Syria have eased and there are no major storms on the horizon, motorists should start to see gas prices retreat," said Jessica Brady, AAA spokeswoman, The Auto Club Group. "Now begins the U.S. refinery switch from the summer to winter blend fuel, which typically means lower gas prices are on the way."
