Models and ensembles this morning indicate that the dry and breezy
trade wind pattern lately across Hawaii will give way to more
showery conditions starting this weekend and into next week.  An
upper-level subtropical ridge coupled with a strong surface high
pressure system will provide relatively dry weather with strong
easterly winds through Friday.  By the weekend, moisture near the
trailing end of a dissipating cold front will increase the chance
of showers across the islands.  Thereafter, models are indicating
a southward trend for cold fronts coming from the mid-latitudes to
reach Hawaii during next week.  The first cold front could become
stationary not too far from Hawaii next Tuesday followed by a
strong cold front possibly moving across the islands on Thursday. 
These fronts will keep a good chance of showers across Hawaii
beginning Tuesday of next week.
