Gas Is Less Than $4 a Gallon in 11 States. How Much Lower Can It Go?

The average price for a gallon of unleaded on Tuesday is less than $4 in 11 states, according to AAA, and within a penny of that threshold in another five. 

The states -- Alabama, Arkansas, Georgia, Kentucky, Louisiana, Mississippi, Missouri, Oklahoma, South Carolina, Tennessee and Texas -- are almost all in the South. Texas is offering the cheapest, at an average of $3.83 a gallon.

The nationwide average is considerably higher -- $4.33 a gallon -- but still a healthy distance from the all-time high of $5.02, reached on June 14. 

The cost could drop even further in the coming weeks, analysts predict. Barring severe weather, outages or other unforeseen disruptions, the nationwide average should fall to $3.99 by mid-August, Patrick de Haan, head of petroleum analysis at GasBuddy, predicted in a July 18 blog post.
