A ridge of high pressure to the north of the state will keep trade winds blowing for the next few days. For now it appears the boundary layer flow will stay just light enough to not need AIRMET TANGO for mechanical turbulence S-W of the higher terrain, but will be keeping an eye on radar VAD wind profiles, soundings, and PIREPS in case something changes. It will be predominantly VFR, but an area of moisture riding in on the trades will bring brief, temporary MVFR conditions to mainly windward sides. These conditions should be most frequent near Maui and the Big Island where the moisture is deeper.
