Strong upper ridging to the northwest of Hawai'i will continue
westward through the week. Heights will remain above normal
through the period, perhaps trending back toward or below normal
as a weakness moves in from the east late this week through the
weekend. 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 see generally lighter windward/mauka
showers. Trades will remain breezy as the surface high to the
northeast dips toward 33N around midweek then back toward 40N this
weekend. Farther east, Hurricane Hilda and the remnants of T.D.
Nine-E may push toward (or partially beneath) the area but there
remains a large amount of spread in track and evolution (including
possible interaction between the two systems). By next week the
moisture associated with the system(s) may be closing in on 150W.
