A typical trade wind pattern, moderately breezy at times, will
prevail with upper ridging over/north of Hawaii. The guidance
shows good agreement on this set up which looks to hold roughly
the next week. Troughing from the north may begin to drop south
towards the islands next weekend, with some weakening and shift to
a more east-southeasterly component of the winds. Overall though
for the next week, drier than normal moisture values are expected,
with not much in the way of rainfall except for the typical
windward and mauka areas.
