A favored composite of reasonably well clustered guidance
solutions indicates that upper trough amplification mainly to the
north of the islands is disrupting trades and driving a moisture
and shower focusing front that is expected to gradually weaken
over the islands over the next few days. Post-system high pressure
bridging to the north of the state should support a return of
moderate to breezy trades heading into the weekend that may be
disrupted again early-mid next week with another digging upper
trough to the north and lead/wet frontal approach into the state.
