A preferred composite of generally compatible model and ensemble
mass field forecast guidance supports a continuation of a
generally benign weather pattern for Hawaii over the next couple
of days with disrupted trades and limited rainfall chances. Winds
veered from the south then southwest over the next couple of days
will increase through the western islands with midweek frontal
approach that remains supported by amplified upper trough approach
and slow passage to the north and increasingly over the state
later this week. Expect enhanced rain chances over the state as
moisture pools within a well defined plume. Trades increase later
week as high pressure re-bridges to the north of the islands in an
expected transition to a more windward terrain focusing rainfall
pattern to tap lingering pooled moisture. Trades may slacken a bit
by next weekend under emerging troughing aloft/just east of the
islands.
