A favored composite blend of the model guidance has good ensemble
support overall in a pattern with average to above average
predictability. Next week will see a return to a pattern featuring
moderate trades overall as high pressure bridges to the north then
northeast of the state. Southeastward digging of an upper-level
trough and surface front from the west-central Pacific
mid-latitudes are forecast to occur to the west early in the
forecast period, bringing a brief disruption to the pattern.
Subsequent higher precipitation chances nearby look to drift
eastward enough to bring showers to Kauai and Oahu
Tuesday-Wednesday. Model trends will need to be monitored as some
of the guidance shows the chance for heavier, more prolonged
rainfall effecting more of the islands.  The associated surface
troughing/frontal boundary to the northwest are forecast to
weaken/dissipate by late week with broad high pressure remaining
in place to the north and moderate, breezy trades continuing over
the islands.
