The national average cost for a gallon of gasoline is likely to continue to fall in the coming weeks, though prices in California will remain elevated due to supply issues, according to an industry expert.

As of Thursday, the national average is $4.289 a gallon, down from Wednesday’s average of $4.305, according to AAA data.

Andy Lipow, the president of Lipow Oil Associates, projected that the national average could slip to $4.10 a gallon in the coming weeks. If this occurs, prices would be down about 23 cents from Friday’s high of $4.33 per gallon, according to AAA data.

The national average has continued to rise since the beginning of the year due to strained supply and increased demand, according to Edmonds. However, Russia’s invasion of Ukraine three weeks ago caused oil prices to surge higher, pushing prices at the pump to levels not seen in over a decade.

Lipow noted that the national average on Feb. 23, right before Russian forces invaded Ukraine, was $3.53 per gallon.
