A more typical trade wind pattern should return today and last
through most of next week as high pressure prevails to the north
of the state. This should support some occasional and light
windward/mountains focus for showers, but otherwise keep much of
Hawaii within a dry pattern over the next week. Guidance still
shows a front approaching but not quite reaching the northwestern
islands this weekend which could briefly weaken the trades, but
trailing high pressure that ultimately settles into the East
Pacific should promote stronger trades from Sunday onward.
Overall, the guidance and ensembles show very good agreement on
the large scale pattern through the next week, with some lingering
uncertainties in the details and timing of systems well to the
north of Hawaii, especially during the middle to latter part of
next week.
