Guidance continues to show a persistent trade pattern over the 
next week or so with precipitable water values tending to be near
or somewhat below climatology. Upper ridging should prevail over 
and north of the main islands into midweek, possibly weakening by 
next Thursday as weak troughing approaches from the east. Thus 
generally windward/mountain- focused showers should be fairly 
light. The modest decrease in heights aloft may lead to a subtle 
increase in rainfall around the end of the period. Initially 
moderate wind speeds should become brisk Friday onward due to one 
high passing by to the north on Friday and then another high to 
the northwest/north around the middle to latter part of next week.
