Gas prices went up slightly nationally, because the supply decreased, said Patrick DeHaan, chief petroleum analyst for Gasbuddy.

“Some areas of the Great Lakes saw prices spike due to price cycling, a local trend, and with the stock market and interest rates heading up there’s been a strong belief that the economy continues to chug along, boosting oil demand in it’s wake as well, leading to an unusual trend in the fall: gas prices that aren’t falling but stable or increasing,” he said.
