Lighter trade winds are expected through the end of the week,
allowing for some land and sea breezes to form. Near normal to
above normal moisture levels should prevail along with troughing
aloft that would lift inversion heights. Thus some showers are
possible following typical land/sea breeze patterns, namely over
windward slopes and coasts at night and interior and leeward areas
during the afternoon, with perhaps even some thunderstorms for the
Big Island. By early next week, trades are expected to strengthen
again to around moderate levels. Model guidance shows moisture
could increase around Sunday and increase coverage of clouds and
showers, before decreasing again Monday-Tuesday, as an upper
high/ridge could sneak atop the state.
