Latest guidance continues to show an extended period of brisk
trade winds in association with a series of high pressure centers
to the north of the state.  Consensus indicates the strongest
winds will be early in the week followed by some slackening
mid-late week, followed by a potential moderate increase around
the weekend as another high reaches north of the area.  Showers
will focus primarily over windward/mountain locations though with
some rainfall extending into other areas at times.  Upper
troughing that should initially be aligned east-west and shift to
northeast-southwest around midweek (GFS/GEFS runs still generally
on the deeper side from that time onward) may provide some
enhancement to rainfall.  The best potential for higher totals
will likely be from Friday through the weekend as a front dropping
down from the north increases moisture.  Latest models and
ensemble means all show this increase of moisture but with some
differences in specifics.  Before then the guidance shows a drier
period with precipitable water below climatological values.
