Average gasoline prices have fallen upwards of around 19 cents per gallon around the state in the past week.

Averaging around $2.44 per gallon, petroleum analyst Patrick DeHaan said even national gas prices have dropped close to 10 cents to $2.42 per gallon.

"As Americans take to the road for Christmas travel, they've all been given a gift that keeps on giving: falling gas prices," DeHaan said. "Americans are saving over $13 million dollars an hour versus gas prices a year ago, adding up to over $315 million every day. Big declines were witnessed in Montana, Michigan, Indiana, Idaho, and Ohio, where average prices fell over 20 cents on average just in the last seven days but everyone has been a winner."

Including the change in gas prices in Montana during the past week, DeHaan said prices yesterday were roughly 57 cents per gallon lower than the same day one year ago and are close to 50 cents per gallon lower than a month ago.

The national average has decreased 41 cents per gallon during the last month and stands 80 cents per gallon lower than this day one year ago.

"Just in the last 24 hours, the national average has declined nearly seven cents per gallon, one of the largest single day decreases ever," DeHaan said. "A sneak peak at our soon to be released 2015 gas price forecast reveals a yearly national average far lower than what we saw this year."
