Trade winds should stay light through much of this week as weak
troughing moves over the region and pushes high pressure well to
the northeast of Hawaii. Periods of showers are expected for most
of the state with locally enhanced activity across the typical
windward and mauka areas. By this weekend, high pressure may again
try to build over the region briefly before another upper
disturbance drifts in from the east. Trade winds should gradually
increase through the weekend, remaining moderately breezy into
early next week. Models and ensembles continue to show fairly good
agreement on the overall large scale pattern with some
uncertainties in the details.
