Light winds this evening will gradually give way to increasing trades late tonight into Thursday. The trades are not expected to be strong enough to require AIRMET TANGO through Thursday.

A relatively dry and stable airmass over the state overnight will begin to destabilize on Thursday as a mid-level trough pushes in from the northwest. The more unstable atmosphere combined with increasing trade winds will cause showers to become more frequent over windward sections, with areas of MVFR conditions and mountain obscuration possible, especially later in the day. AIRMET SIERRA may be required for mountain obscuration at that time. There will also be a slight chance of thunderstorms over at least windward sections of the state beginning late Thursday or Thursday evening.
