Mainly dry and cool post-frontal air should prevail for the
remainder of the weekend as the slow-moving cyclone located well
north of the state moves farther away.  A developing low pressure
wave associated with the next front will approach from the
northwest by Monday.  This system will attempt to combine with
returning moisture from the previous front off to the southeast. 
A period of rain/showers ahead of the cold front can be expected
to sweep across the islands on Tuesday.  Meanwhile, there has been
a model trend of keeping the axis of heavy rain associated with
the previous front from reaching the Big Island on Tuesday. 
Thereafter, the global models are now unanimous in taking the
amplifying wave well to the north of Hawaii.  Towards the end of
next week, there are increasing model signals for an upper low to
form to the east of Hawaii.  Only the latest GFS indicates a
surface reflection of the upper low at this time.
