High pressure north of the state will keep moderate trade winds in place today and tonight, with low clouds and showers favoring windward slopes and coasts. Some MVFR conditions can be expected as showers move through, with Kauai and Oahu the most likely targets, particularly through mid morning. Predominantly VFR conditions are expected across the island chain late this morning and this afternoon, although some brief MVFR cigs will remain possible, particularly across Kauai. Trade showers will likely increase again tonight, mainly in windward areas.

AIRMET Sierra remains in effect for mountain obscuration across windward sections of Kauai and Oahu. This AIRMET will likely remain in place through mid morning.
