.Synopsis for the Hawaiian offshore waters...
A low pressure system will drop into the Hawaii region from the
north and become cut off from the westerly steering flow and
linger northwest of Kauai through Thursday. Southerly to
southeasterly surface winds will draw up tropical moisture over
Hawaiian waters under the cold upper low, producing periods
enhanced showers, heavy at times, with the potential for a few
thunderstorms over western waters during this time. A passing low
level trough will then drift from east to west through the
region from Sunday into the first half of next week, potentially
extending these unstable wet weather trends.
