Looking Ahead

A low pressure system and weak cold front northwest of the Hawaiian Islands will slowly lift northward today. High pressure will then build back in north of the state on Friday allowing a return to a wet trade wind weather pattern into Saturday. Drier air will filter in from the east on Sunday with decreasing cloud and shower trends through Monday. Light south to southeasterly winds will bring a return to hot and humid weather around the middle of next week with additional showers as another low sets up northwest of the state.
