How gas prices have changed in Jewell County, Kansas in the last week

Gasoline prices have risen for the past three weeks, charting an almost 10-cent increase.

Analysts point to refinery issues and the coming switchover to summer fuel blends as a reason that increase could continue in the weeks ahead. The largest weekly increases are "likely coming in March and April," GasBuddy analyst Patrick De Haan said in a statement Monday.

Some domestic refineries are undergoing maintenance, and several are having issues. A fire was reported Friday at a Phillips 66 refinery in Billings, Montana. An electricity failure drove the shutdown of a BP refinery in Indiana. The cold winter weather has also knocked out some refineries in the past week. When refinery output drops, Americans can typically expect to see slight upticks in the cost of gasoline in their regions.
