MADISON (WKOW) -- You may want to fill up now, gas prices are expected to keep going up.
AAA says the cost has risen for 32 straight days already.
The national average is now around $3.70 per gallon.
In Madison, the highest price listed on gasbuddy.com is $3.85.
AAA says the hike is due to rising crude oil prices and production cuts, plus several oil refineries have shut down for maintenance before switching to a summer blend of gas.
Gasbuddy.com predicts prices will start to drop around Memorial Day.
