It's happened again....gasoline prices have taken another big leap in Iowa, rising a dime a gallon in the past 24 hours and 50 cents a gallon in the past month.

Many Sioux City stations are now at $3.59 a gallon for regular unleaded gas. Pam Moen at Triple-A, says a jump in crude oil prices and production problems are largely to blame.


Pump prices are unlikely to head back down any time soon, she says, with many refineries getting ready to start producing summer-blends of fuels.



The statewide average for a gallon of gas is three-58. That's up ten-cents a gallon in the past week and it's up 50-cents a gallon in the past month. Iowa's current average gas price is three-cents below the national average.
