Temp gauge slightly higher than normal. on 2006 Buick Lucerne

The gauge is showing one or two hash marks high, occassionally goes higher and blows cold air from heater. After getting that high, goes back to normal and stays there. Usually does this when the car has sat for 30 minutes or more. The cooling fans are running during this time.
