ST. JOSEPH, Mo. (News-Press NOW) — Gas prices in Missouri remained steady in the wake of a winter storm that impacted the state last week. In St. Joseph, the average gas price is $2.37 per gallon, lower than the average price of $2.71 motorists saw at this time last year. In Kansas City, Missouri, the average price is $2.44 per gallon. A combination of tight supply from reduced refinery operations and stronger demand has caused an increase in crude oil prices, resulting in a pause on gasoline price decline.
