Valid 00Z Sat Nov 26 2016 - 00Z Sat Dec 03 2016

The models and ensembles show the low to mid level high persisting
northeast of  Hawai'i Sun/Mon, with a new high building near 38n
150w 12z Tue that moves east with a ridge extending southwest from
the high that extends north of the islands.
Aloft, an upper low east of the islands builds west with cyclonic
flow aloft next weekend. Generally light precipitation is
expected, focused in windward upslope locations.  The GFS/ECMWF
models forecast a plume of moisture to return late next week into
next weekend Dec 02-04, along with an inverted trough slowly
approaching from the west.  This combination will need to be
watched for potential to produce more significant to possibly
heavy rainfall.
