Guidance reasonably agrees in support of brisk island trades this
week as strong high pressure settles to the north of the state. A
drier airmass suggests that daily windward/mountain-focused
showers should be limited into late week. Rainfall potential
should gradually increase by the 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 is expected
to develop over the state as high pressure shifts into the eastern
Pacific and as an upper trough/low settles near Hawaii. Trades
will tend to ease, veer and increasingly tap deeper shower fueling
moisture in this scenario, especially into the eastern islands
early next week.
