...Heavy rainfall threat continuing through Sunday...

An upper low and surface system will track eastward to the north
of Hawaii early week, continuing to support heavy rainfall
potential along the surface front as it sinks southward through
the islands. The best potential for heavy rain/flooding impacts
should focus across more western islands where moisture anomalies
are highest, but organized rainfall will eventually impact the
other islands as well early in the week as the cold front weakens.
After this, guidance continues to show an overall general
consensus that surface high pressure should again build north of
the state, allowing for a return to breezy easterly trades and
showers favoring the typical windward locations later next week
and into the weekend.
