Upper ridging will nose in from the west and likely remain into
next week. Lower level moisture is forecast to increase from the
east/southeast (precipitable water values 1.00-1.50 inches) late
Thu into early Fri but overall mid-level moisture levels will stay
on the drier side. As a result, only scattered windward/mauka
showers are forecast, but this will be dictated by sea/land
breezes when trades are weak on Tuesday into early Wednesday.
Trades may become modest to breezy late in the week as a surface
high slips eastward just to the north of the area before returning
to more typical levels next week as a front approaches Kauai but
likely stays a couple hundred miles to the northwest. A blended
solution between the GFS/ECMWF should suffice as they differ a bit
in how much to erode the upper ridge next week.
