---- — Just in time to make driving to grandma’s house a little more expensive on Thanksgiving Day, gasoline prices reversed a downward trend and turned slightly higher last week. Tracking by the auto club AAA showed a small, seven-day increase in average gas prices in Massachusetts, New Hampshire and across the United States.
The regional and national averages rose by just between two to three pennies per gallon for self-service regular gas, the auto club found. But the increased represented a change of direction after 10 weeks of falling gas prices in Massachusetts and New Hampshire, and four weeks of decreases for the national average.
The Massachusetts average price for self-service regular rose to $3.354 on Wednesday, a 2.7-cent increase from the prior Wednesday’s $3.327, AAA reported. But Wednesday’s average remained 27.2 cents lower than the state-wide average on the same day last year, which the auto club put at $3.626.
In New Hampshire, a 2.2-cent increase brought the state average to $3.278 for self-service regular on Wednesday, compared to $3.256 seven days earlier, according to AAA. On the same day of 2012, the Granite State average of $3.519 was 24.1 cents higher than Wednesday’s figure.
AAA’s 50-state average for self-service regular gas bumped to $3.212 on Wednesday, up 2.6 cents from the prior Wednesday’s $3.186. On the same day last year, the U.S. national average of $3.412 was 20.0 cents above Wednesday’s level.
