Kansas gas prices are on the rise, increasing six cents from a week ago to an average of $2.17 per gallon, according to a AAA Kansas news release.

The national average reached $2.32 per gallon, which is four cents higher than a week ago and the highest in the past six weeks, the release said. With an 11-cent jump in July, Kansas’ increase is the eighth largest in the nation, according to the release. Even with the spike in July, Kansas gas prices are still 12th lowest in the country, Jennifer Haugh, AAA Kansas spokeswoman, said.

“Compared to much of the rest of the country, Kansas is still in a good position with relatively affordable gas prices, compared to the national average,” Haugh said. “But as we enter the dog days of summer, supply and demand has pushed our prices higher, and we expect this trend to continue.”
