It appears that typical trade wind pattern will prevail through
much of next week.  A mid to upper-level cut-off low with
scattered thunderstorms will pass well north of the islands and
rejoin the westerlies during the next few days with little impacts
on the weather in Hawaii.  The subtropical high pressure system
will continue to dominate the weather early next week.  By the
middle of next week, the tail end of a cold front dipping down
from the higher latitudes should result in some slackening of the
trade winds. Toward the end of next week, a lingering upper-level
low west of Hawaii will appear to pull upper-level moisture
northward from the ITZC with little impacts on Hawaii`s weather.
By next weekend, a weak wave in the easteries could approach the
Big Island, possibly with a slight increase in rain chances.
