Drivers in northwest Wisconsin are seeing some of the lowest gas prices in the state this week, as Wisconsin's average price for a gallon of regular fell below $4 for the first time since early September.

The statewide average was $3.92 on Monday, Nov. 9, according to AAA. That is a drop of about 30 cents from a week ago and 60 cents below the peak of $4.52 recorded on Oct. 24. The last time the average was below $4 was Sept. 9, when it was $3.97.

Among Wisconsin metro areas listed by AAA on Nov. 9, Eau Claire had the lowest average at $3.70 a gallon. Superior was listed at $4.00, and the Pierce-St. Croix County area at $3.94, compared with a national average of $4.01.

Analysts cited seasonal factors for the decline, including the completed switch to cheaper winter-blend fuel and refiners ramping up output as demand fades with cooler weather. GasBuddy analyst Patrick De Haan said prices have fallen in the 30 days leading up to the election in most years since 2006 for seasonal reasons, and that prices could continue trending down if global market concerns stay settled.
