Typical and breezy trade wind pattern with some occasional and
light windward/mountain focus for showers is expected with high
pressure in place north and east of the state this weekend. A
trough is expected advance to the north by Sunday, then shift
southeast Monday before it retrogrades to the west midweek. This
change will disrupt the trade winds however the associated surface
cold front should stay to the north of Hawaii, so sensible weather
impacts should be limited. The breezy trade winds should return by
the middle of next week as high pressure again builds in to the
north and a cutoff low settles to the east of Hawaii. As this low
drifts it my draw in increased moisture with the possibility of
increased shower activity for the Big Island and Maui. There is
spread with the guidance on how much moisture and the location of
this low feature.
