A high far northeast of the state will remain nearly stationary and weaken. Trade winds will be replaced with light and variable winds on Wednesday night as a cold front approaches the islands.
A front far northwest of the islands will move southeast, reaching Kauai Saturday night and pushing south of the Big Island on Sunday. A new high will build north of the area behind the front, returning trade winds to the islands.
For the Bruno Mars concerts, no heavy rain is expected. Temperatures may feel a bit chilly for Hawaii standards on Saturday and Sunday.
