Projection: $4 gas could return as soon as May

(CNN) – Gas prices are way down from the record highs they hit last summer, currently at just over $3 a gallon.

But don’t get used to it just yet.

According to Gas Buddy, an app that tracks gas prices, the price at the pump could rise to $4 a gallon by May.

That’s significantly cheaper than the spike that topped $5 a gallon earlier this year.

The prediction is based on the higher cost to produce summer grade gasoline. Plus, more Americans hit the road in warmer months.

However, Gas Buddy admits there’s a lot of uncertainty in gas prices, and accurate predictions are challenging.
