Hawaiian trades are expected to build to brisk levels for the
coming week as the southward drift of Pacific high pressure
strengthens the gradient over the state. Drier air moves in, so
daily windward/mountain-focused showers should be limited.
Rainfall potential should gradually increase late week into 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 develop over the state in
this pattern, so trades may gradually shift more southeastward and
eventually tap deeper moisture.
