A stationary front is currently stalled over Kauai, providing
convergence in a rather moist environment with some instability in
place due to an upper trough aloft. This has led to widespread
showers there, which could remain over the next several hours.
Though the front will dissipate over the next day, its remnant
moisture could linger there and sink slowly southward later in the
week. A reasonably strong surface high is expected to build north
of Hawaii and cause breezy trades, and windward/mountain showers
are possible in this moist pattern. A period of upper ridging over
the weekend should weaken trades somewhat. By next Monday-Tuesday,
another upper trough is forecast over the state, and recent model
runs show enhanced moisture coming in from the south. This could
increase shower activity but there is uncertainty in the details
at this point.
