A rather wrapped-up upper low, currently located about 300 miles
southwest of the Big island, should continue to weaken and drift
southwestward over the next day or two. This also includes a
decaying inverted surface trough extending southwest to northeast
across the state. By Wednesday, the operational and ensemble
guidance indicate upper ridging will build across the state and
remain intact through the upcoming weekend. This should allow more
traditional light to moderate trades to return with possible
windward showers. Early next week, ensembles show a rather
amplified upper trough and upper vortex transitioning across the
Pacific, including a strong surface cold front, which will attempt
to reach the Islands but it appears at the moment the upper ridge
holds on.
