The AAA Texas Weekend Gas Watch says the statewide average gas price in Texas is $2.84 a gallon for regular unleaded. That price is up three-cents from a week ago, and is 93-cents higher than a year ago. The national average is $3.16. Gas demand is down sharply from the holiday weekend, but crude oil prices are above $70 a barrel. Pump prices will likely remain high throughout the summer driving season. The average price at the pump in San Antonio is $2.78.
