A moist and unstable airmass will remain in place over the state through Monday. Periods of showery weather will affect the island chain through Monday, with clouds and showers favoring windward and mauka areas. Sea breezes will also result in leeward showers through this evening and again Monday afternoon, with showers also possible through the overnight and early morning hours. Isolated thunderstorms will remain possible across interior and leeward sections of the Big Island through early this evening and again Monday afternoon. MVFR cigs/vsbys will be possible in windward areas through the next 24 hours, with these conditions being most common during the overnight and early morning hours. PHLI, PHTO, PHMK and PHNY are the most likely TAF Sites to see reduced cigs/vsbys. Elsewhere, predominantly VFR conditions are expected. Moderate trades will prevail through Monday, thanks to a ridge of high pressure to the north of the islands.

AIRMET Sierra is in effect for mountain obscuration across the Big Island. Conditions should improve in leeward areas later this evening, but will likely hang around for windward areas through the night. The AIRMET will likely need to be expanded to include windward sections of the other islands tonight.
