CHICAGO - Gas prices around Chicago keep climbing.
AAA reports the average price across the area is $3.56 a gallon, more than a dollar higher than last year.
It's up a nickel a gallon over last week.
AAA says late summer demand could keep prices high into September.
The nation's average gas price rose 1.7 cents per gallon over the past week, notching $3.16 per gallon, according to GasBuddy, which compiles data from more than 150,000 gas stations across the country.
The national average is now 3.8 cents higher than it was a month ago and nearly 92 cents higher than a year ago.
Overall, prices at the pump this week are already nearly $1 more than they were compared to a year ago, according to GasBuddy.
PRICE Futures Group senior analyst and FOX Business contributor Phil Flynn told "Cavuto: Coast to Coast" this week that the infighting within OPEC and ongoing friction with allied oil-producing countries have the potential to push gas prices to $3.50 or $4 per gallon.
