A large upper ridge and expansive surface high will tend to
meander across the central Pacific through much of this week, with
the strongest pressure gradient and surface winds likely staying
north of the Islands.  Meanwhile, an upper low approaching from
the east should reach the Big Island by late Wednesday and then
lift northward.  Upper level ridging builds back in by the weekend.

Trade winds are expected to decrease some going into mid-week as
the dominance from the central Pacific high lifts farther to the
north.  In terms of rainfall, typically trade enhanced showers
will be the norm through about early Wednesday, with perhaps
greater coverage of showers for the end of the week from Oahu to
the Big Island as the upper low passes overhead.
