Montana's gas prices rose a little over five cents in the last week to reach an average of $3.56 per gallon. Meanwhile, the national average has begun tapering down, rising only 2 cents per gallon in that same time period to reach an average price of $3.70.

According to Gas Buddy Petroleum Analyst Patrick Dehaan, the national average "may have peaked," however, DeHaan cautions that the price drop is simply a result of refining issues being resolved in California and the Great Lakes Region.

Gas prices typically drop in mid September. At the moment, Montana's gas prices are 15 cents lower than they were at the same time last year, and 13 cents higher than a month ago. The national average has skyrocketed up 21 cents in just four weeks, but appears to have reached a plateau earlier this week.
