Latest model and ensemble guidance provides a fairly agreeable
forecast over the next seven days.  The period from now into early
next week will feature a somewhat wet and moderate to brisk trade
pattern, with primary rainfall emphasis over windward terrain.  A
weakness aloft drifting across the islands around the periphery of
a strong ridge to the northwest will provide some enhancement to
activity.  By mid-late week an eastward extension of that strong
ridge will sag southward as will the weakening surface ridge to
the north of the region.  Moisture will decrease, with some
locations possibly seeing precipitable water values below one inch
for a time, and trades should trend lighter as the surface
gradient weakens.  This evolution will likely lead to lighter
rainfall for the Wednesday-Friday period.
