Breezy trade winds across Hawaii today should weaken today and
continue through the first half of the week as surface high
pressure slips to the northeast of the state and a cut-off upper
low meanders west of the islands. The models continue to indicate
that implications for sensible weather across Hawaii with this
system seem relatively minor, with mainly scattered windward
showers possible within a relatively dry airmass (PWs only around
1 to 1.5 inches). This should limit the potential for any heavy
rain. Models and ensembles agree that by mid to late week, this
upper low weakens and high pressure re-establishes itself north of
the state. Expect normal breezy trade winds to briefly resume,
before weakening again next weekend as another easterly wave/upper
low moves towards the state.
