Expect trades of varying strength through the period.  Surface
ridging well north of the state will evolve in shape and location
but ultimately support persistent easterly winds on average. 
Relative to the rest of the period, trades may be a little weaker
during the weekend.  Shower activity from now into early next week
should trend lighter by Tuesday-Wednesday with a decline in
precipitable water values to 1.00-1.25 inches and perhaps slightly
lower, at least one standard deviation below normal.  Upper level
energy in the southern fringe of the westerlies will drop
south/southwest to the west of the state Sunday-Monday and could
locally enhance rainfall primarily on Sunday.  Also the weaker
trades on the weekend could allow sea breeze boundaries to have an
influence on rainfall versus a more windward focus during most of
next week.
