Latest model and ensemble solutions seem well clustered over the
next week, bolstering forecast confidence. A composite solution
seems reasonable. High pressure bridging to the north of the state
over the next couple of days will settle to the northeast of the
islands later weekend into next week. In this pattern, trades will
increase to moderate and occasionally brisk levels. Trades will
also tend to turn east-southeasterly next week as high pressure
strengthens further while settling over the eastern Pacific and a
front comes into the picture well west of the main islands. Expect
a trend toward fairly light windward-focused showers into the
weekend under stable upper ridging with limited moisture.
East-southeasterly low level flow next week would gradually
increase moisture while a modest weakness aloft may develop over
the area. Thus rainfall could increase.
