Pennsylvania gas prices increased by 13 cents this week to $2.603 per gallon, according to AAA East Central's Gas Price Report.

Pump prices increased by 6 cents on the week, by 18 cents per gallon on the month, and are up by 36 cents on the year.Retail averages in the Mid-Atlantic and the Northeast region continued to climb higher throughout the busy holiday travel weekend with drivers paying the highest New Year's gas prices since 2014. The New Year also brings gas tax increases for drivers in Pennsylvania (an additional 7.9 cents).Typically, domestic demand falls in January, so higher gasoline production may lead to a stock build in the coming weeks and could have a bearish market impact on gasoline.
