How Will Winter Storms Impact Gas Prices After Iran War Related Spikes?

Winter weather is back in many parts of the United States, and drivers who are already reeling from rising gas prices could be facing another spike in their costs at the pump.

After a brief flirtation with warmer weather in most of the East Coast, a pair of snowstorms are in the forecast for the Upper Midwest and Great Lakes, with heavy snow likely in parts of Minnesota, Wisconsin and Michigan.

The average price of a gallon of regular gas in the U.S. on Friday, March 13 was $3.63, according to AAA Auto Club. That’s up from an average of $3.32 one week ago on March 6 and one year ago $3.07 on March 13, 2025, the group said.

“In just a week, consumers have seen gasoline prices surge at one of the fastest rates in years after oil prices spiked following U.S. strikes on Iran and the effective closure of the Strait of Hormuz,” Patrick De Haan, head of petroleum analysis at GasBuddy said in a March 9 blog post.

Now many of those same drivers could be facing another jump in pump prices as winter weather moves back in several parts of the country.

With all of that in mind, the USA TODAY Cars team took a look at gas price averages during other winter storms to see the impact they had on gas prices at those times.

What happened to gas prices the last time there was a big snow storm in many parts of the country?

In January and February 2026, a pair of winter storm dumped several inches of snow and sleet on most of the east coast, with cities like New York City and Philadelphia getting over a foot of snow. The storm caused supply disruptions push the national average price of gas to at the time to $2.87 per gallon, according to AAA.

The average price of a gallon of regular gas in January 2026 was $2.81, according to the U.S. Energy Information Administration.

Gas price before storm: $2.89
