In Sacramento, the average was $3.42 a gallon, a 16-cent spike in one month and nearly 52 cents higher than this time past year.
Locally, prices are lower, with the Lincoln average sitting at just under $2.63 a gallon and the state average at $2.59, according to AAA.
What's worse? While analysts are predicting a 15-cent surge this week, "Prices could rise even more, depending on how the crude market responds to the latest news of a US missile strike over the weekend", AAA spokesman Mark Jenkins said.

The report notes, "regional differences in retail gasoline prices can be significant".
