The islands will be under the gradient in the southwestern
periphery of eastern Pacific high pressure, yielding moderate
trades on average with slight fluctuations on the stronger or
weaker side at times.  At least through Wed precipitable water
values are forecast to be within a tenth of an inch of 1.25 inches
at most locations.  Thus generally windward focused rainfall
should be mostly light through midweek, though a weakness aloft
moving westward across the islands Mon-Wed could offer modest
enhancement.  Current guidance indicates any tropical development
should remain well south and east of the state, and to a greater
extent than the 00z CMC.  However with differing timing GFS/ECMWF
runs agree upon the potential for a pocket of greater deep
moisture extending northward from the tropics to cross the region
around Thu-Fri, so a period of locally heavier activity is
possible at that time.
