Upper ridging will strengthen to the northwest of Hawai'i and
continue westward through the week. Heights will remain above
normal through the period, despite a weakness moving in from the
east. With mid-level moisture remaining rather low (PWs around
1-1.5" and 700-400/300-850mb RH 5-20%), most of the area will
remain drier than normal and generally lighter windward/mauka
showers. Trades will remain breezy as the surface high to the
northeast dips toward 33N around midweek. By then, a few more
showers may be expected over the region beneath the weakness
aloft. Farther east, Hurricane Hilda and T.D. Nine-E may push
toward (or beneath) the area but there remains a large amount of
spread in track and evolution (inclusing possible interaction
between the two systems).
