Today's guidance shows very good agreement for the overall
forecast through next Thursday.  High pressure north of the state
will vary in shape and location from day to day but maintain
support for moderate to possibly occasional brisk trades along
with a general windward/mountain emphasis for showers.  The
combination of a ridge aloft and relatively modest moisture should
keep rainfall amounts light from late this week into the weekend. 
As a stronger upper high tracks to the northwest of the main
islands and settles to the north, the deep-layer flow around the
high will bring an area of enhanced moisture (precipitable water
values 1.50 inch or greater) into the state from the northeast
starting late Sunday or soon thereafter.  Moisture should remain
above climatology through midweek with a decreasing trend by next
Thursday.  With the added moisture anticipate somewhat higher
rainfall totals in the Monday-Wednesday time frame.
