FORT WAYNE, Ind. (WOWO): Gas prices in Fort Wayne have gone up nearly a quarter per gallon in the last week alone, and they could stay this price for some time. According to analyst Patrick DeHaan with www.gasbuddy.com, as of Sunday night, there are no states with averages under $3/gallon. However, he also says this trend won't last forever. Because January and February usually see weak demand, gas prices should stay moderate the next couple of months.
