Models and ensembles reasonably agree that Hawaiian trades will
build to brisk levels this week as the southward drift of potent
Pacific high pressure strengthens the gradient over the state.
Drier air filters in, so daily windward/mountain-focused showers
should be limited into late week. Rainfall potential should
gradually increase by next weekend as a favored composite of
models and ensembles show decreasing heights aloft as the upper
ridge to the north of the state weakens in response to digging
trough energies. Lower atmospheric inverted troughing may also
begin to develop over the state by then, so trades could tend to
ease, veer and increasingly tap deeper moisture.
