Today's guidance consensus continues to show a persistent trade
pattern for at least the next week with some oscillation of wind
speeds and generally light showers tending to favor windward
locales.  Some localized land/sea breezes could briefly develop
during times when the background flow is weakest.  An area of
greater deep moisture passing through early this week will provide
some modest enhancement of rainfall into early Tuesday.  After
this moisture departs there is good agreement on precipitable
water values settling to below normal values of near to below 1.25
inches after midweek and extending into early next week. 
Continued retreat of Northeast Pacific high pressure will lead to
weaker trades through Tuesday.  Then a surface high building
closer by to the north of the state will support stronger trades
Wednesday to Thursday night.  This high and the trades are likely
to weaken Friday-Saturday, followed by a steady pattern Sunday and
some strengthening Monday as high pressure to the north and
northeast of the state builds again.
