A weaker pressure gradient will remain temporarily in place for
Sunday due to a front north of the state, leading to lighter to
moderate trade winds. These winds could still serve to focus
showers over favored windward areas as a weak trough/low aloft
provides a slight increase in instability for more clouds and
possibly shower coverage. By Monday and through around Thursday,
trades should strengthen to breezy levels as a reasonably strong
surface high will come into place over the Pacific well north of
Hawaii (near 40N). Showers mainly in windward areas can be
expected, but some may make it to leeward areas given the strength
of the winds. Trades are forecast to lessen some by late this week
as the high shifts east and weakens. Available moisture and shower
coverage are more uncertain but may decrease late week as an upper
ridge builds just west of the state.
