According to AAA, the rise in gas prices comes from an increase in demand and tight gasoline stocks.

“Drivers in Texas are seeing some of the cheapest gas prices in the country, but the statewide average jumped a whopping 29 cents per gallon in just the last month,” said Daniel Armbruster, AAA Texas spokesperson. “On a national scale, AAA forecasts that gas prices will trend up moving through the spring and into the summer, which, of course, means higher pump prices are likely for Texas drivers too.”
