Water vapor imagery shows a nearly stationary lingering trough/low
over the state in a pattern with light trades underneath modest
high pressure to the north of the state. The high weakens over the
next couple of days as a front settles north of the state in
response to amplified mid-upper level trough passage across the
northeast Pacific. This disrupts trades and allows formation of a
pattern with sea/land breeze showers under gradually stabilizing
flow aloft well into next week. Meahwhile, a tropical disturbance
now well southeast of the Big Island is slated to pass to the
south of the islands over the next few days that could temporarily
act to increase winds a bit and allow some associated moisture to
skirt the southern islands.
