Latest models and ensembles are fairly consistent and agreeable
with most aspects of the forecast for the next seven days.  Expect
strong trades/windy conditions for most of the week as surface
high pressure settles north of the state between 30-40N latitude
and an upstream high provides reinforcement around midweek.  Winds
will likely weaken somewhat by next weekend as high pressure moves
into the eastern Pacific and a cold front crosses the central
Pacific.  Rainfall during the period should focus over windward
terrain but may stray into other locales at times.  The
combination of rising heights aloft as ridging builds to the
northwest and precipitable water values declining to around 1-1.25
inches (0.5-2 standard deviations below normal) should lead to
amounts in the lighter half of the spectrum for several days.  By
next weekend guidance expects ridging aloft to weaken but with
only a slight increase in moisture, so showers should remain
fairly light.
