This weekend into early week, a mid-upper trough/low will shift
westward over the state. This and a possible weak surface trough
could allow for increased moisture and showers, especially over
favored terrain. As these features exit, there looks to be reduced
support for showers once again through later week with return to a
drier trade wind pattern with more spotty and uncertain upper
impulses to contend with locally. A favored composite of
reasonably well clustered guidance indicates that high pressure
bridging to the north of the islands and passage to the south of
the state of a series of tropical disturbances this week out from
the ITCZ being followed by the CPHC may support moderate to breezy
island trades.
