Mainly quiet weather is forecast for Hawaii through the end of the
week, with low amplitude upper level ridging overhead leading to
near to below average moisture/precipitable water values and
fronts dissipating well north of the islands. By early next week,
however, an upper trough is forecast over the Pacific extending
into Hawaii. This is forecast to push a cold front through the
northwestern islands by around Tuesday and stall. This could
provide a focus for rain as moisture increases to above average
along the front, with showers especially for windward and north
facing slopes, although nothing major is currently expected.
Behind the front, a reasonably strong surface high is expected to
build north of Hawaii, leading to increasingly breezy easterly
trades (more northeasterly for the northwestern islands) by
midweek and beyond.
