Trade winds should remain fairly weak the next day or so as a
front to the north of Hawaii slides eastward but trades and shower
chances look to rebound some again by the weekend as high pressure
expands north of the state. The surface high to the north should
get pushed eastward and become established and strengthen to the
northeast of Hawaii early next week allowing for stronger
(moderate to breezy) trades and increased shower activity for
mainly windward facing regions. There remains good synoptic
agreement on this overall pattern, but there are some differences
in the details and timing of systems that should stay well to the
north. A general model compromise between deterministic and
ensemble mean solutions should help smooth out any of these
differences for now.
