Most guidance displays a continuation of the trade pattern over
the next seven days with some variability in wind speeds.  Showers
will tend to favor windward locales but there may be some land/sea
breeze influence during times when trades are relatively weaker. 
Rainfall totals will likely be in the lighter half of the spectrum
as consensus is persistent in showing precipitable water values
declining to near or below 1.25 inches for most of the time after
midweek and into early next week.  Initially light-moderate trades
should trend somewhat stronger Wednesday-Friday as high pressure
builds north of the state, followed by a lighter trend during the
weekend as the high weakens.  Winds may strengthen a little next
Monday-Tuesday with most guidance rebuilding the surface high a
bit.  However by then low-predictability aspects of evolution
aloft farther to the north (00Z CMC having the least confident
solution) lead to some questions over exactly how strong the
surface high will be.
