Breezy trades may hold through Friday with upper/surface highs
centered northeast of Hawaii, but these features weakening will
cause winds to weaken as well by Saturday. Meanwhile to the
northwest of the state, upper/surface lows will track slowly
eastward into this weekend and early next week. In response to
these features, winds are likely to veer a bit and may become
east-southeast. Winds are forecast to stay at weak to moderate
levels and perhaps become a hybrid trade and land/sea breeze
pattern. Minor moisture plumes may also be drawn into the state at
times, with the first Friday night into Saturday increasing
showers particularly over windward areas of the Big Island
according to the HREF. Generally windward showers will be the main
chance for precipitation, since the upper ridge east of Hawaii is
likely to block the western lows/associated frontal system and any
heavier precipitation from reaching even the northwestern islands
through early next week. What is left of the weakening trough may
move across Hawaii around midweek or so. By the later part of next
week, surface high pressure is forecast to move north of the state
and promote strengthening easterly trades.
