IRVING, Texas (AP) -

Retail gasoline prices across Texas have jumped 6 cents per gallon this week.
    
AAA Texas on Thursday reported the average price at the pump statewide reached $3.01 per gallon. Nationwide gasoline prices rose 3 cents, to hit $3.22 per gallon.
    
The association said gasoline price increases in the Midwest were partly a result of heavy storms and concerns of potential refinery disruptions. AAA said overall impact appears limited.
    
Amarillo has the cheapest gasoline in Texas at $2.92 per gallon. Drivers in Texarkana and the Austin-San Marcos area are paying the most at $3.04 per gallon.
    
AAA said Texas is among the top 10 states with the least expensive gasoline a week before Thanksgiving. The group projects about 3.4 million Texans will travel during next week's five-day holiday period.
