Breezy/gusty trades will continue to diminish into Saturday as the
surface high to the northeast of the region moves to the east.
Upper heights will lower as a trough to the northwest of Hawai'i
pushes eastward with its attendant surface front approaching Kauai
early Monday. This may slip through Oahu/Molokai and dissipate
next week with generally light showers as precipitable water
values fluctuate around an inch and heights rise. By Tuesday into
Wednesday, upper ridging will build along/east of 180 which may
act to tug some troughing back westward from around 140W. This may
enhance rainfall late in the week, but otherwise a return to more
typical trades around the middle of the week should only support
light to locally modest showers. With the GFS just a bit lower
with troughing by the end of the period compared to the ECMWF, a
blend should suffice.
