PITTSBURGH — Gas prices in Western Pennsylvania increased by about five cents this week to $2.667 per gallon, according to AAA East Central’s Gas Price Report.

Today’s national average price for a gallon of regular unleaded gasoline is $2.41. This price is two cents more expensive than one week ago, 12 cents more than one month ago and 30 cents more than one year ago. The national average has now increased for 20 consecutive days, and pump prices in 43 states and Washington D.C. have moved higher over the last week. This increase was most prevalent in the East Coast region where refiners wrapped up seasonal turnaround resulting in significant prices increases last week.

Pennsylvania ($2.64) lands on the list of top 15 most expensive markets, as the region made the final switch to summer-blend gasoline last week. Pennsylvania also had one of the largest weekly increases, increasing 5 cents. Compared to this same time last year, Pennsylvania is seeing significant increases at the pump. This trend is likely the result of the region’s move toward less substantial gasoline imports.

The highest in the region was in Jeannette at $2.722; the lowest in Sharon at $2.517; and Bradford’s was at $2.722.
