Surface high pressure rebuilds north of the state near 35 degrees
north through the end of the week, with mainly east to ENE trade 
wind flow expected, with good overall model agreement across the 
Hawaii domain. A weakness likely develops in the subtropical ridge
axis by Sunday north of the state, with some reduction in the 
trades possible. In terms of rainfall prospects, mainly trade 
wind induced showers can be expected most days across the windward
terrain. There may be some heavier showers across the central and
northern Islands going into Thursday night and Friday, but does
not appear to be a major event.
