The national average price of gasoline is likely to spend much of the summer in the range of $3.35 to $3.85 per gallon, an industry analyst said.

But Patrick De Haan, head of petroleum analysis at GasBuddy, said it could go higher “if unexpected refinery outages flare up or we see a major hurricane or economic development.

“While gasoline prices have inched up slightly, we’re still faring much better than we did last year, when the national average started to soar after Memorial Day on its way up to the $5-per-gallon mark,” he said.

“In addition, gas prices may temporarily rally if there’s a debt ceiling deal that passes through Congress in the weeks ahead, based on the optimism that such a deal could avert a major recession, keeping oil demand stronger this summer.”

The state and nation set their highest recorded averages nearly a year ago — Pennsylvania reached about $5.07 per gallon June 12, while the national average peaked at $5.02 on June 14, according to AAA.

In the past week, the national average price has increased, while the Pittsburgh-area average fell slightly.

According to AAA, the national average was about $3.58 per gallon Monday. That’s about 4 cents more than a week ago, but about 3 cents less than a month ago and $1.04 less than a year ago.
