The potential for hurricane developments and forecasts of an expanding heat dome over Texas, Oklahoma and Kansas this week could push oil prices higher, according to Andrew Gross, an AAA national public relations manager. Refineries in those states might have to curb production to deal with the sizzling temperatures, Gross said.

The cost of oil accounts for more than 50% of the pump price, according to Gross.
