"An uncharacteristically early price jump" - "the most dramatic in nearly two years" - has ended the downward trend in gasoline prices since late summer, according to AAA.
In just one week, the average price for a gallon of regular shot up 18 cents across the Philadelphia region, AAA Mid-Atlantic reported Tuesday.
In Philadelphia and its four neighboring Pennsylvania counties, the average for regular Monday was $3.67 a gallon.
In South Jersey, it was $3.52.
This morning, both were another penny higher, according to AAA's Daily Fuel Gauge Report ( www.fuelgaugereport.com).
Delaware gas prices rose even more - up 21 cents in a week, to $3.62 as of Monday.
