NEW YORK -- Retail gasoline prices continued to climb Friday ahead of the Memorial Day weekend and the unofficial start of America's summer driving season, according to The Associated Press.

The national average pump price increased nearly 3 cents overnight to $2.391 a gallon, according to auto club AAA, Wright Express and Oil Price Information Service. Gasoline prices ticked higher every day this month.

Gas prices surged higher though a crude rally appears to have stalled.
