Expect light trade flow with limited showers over the next couple
of days as a front settles to the north of the islands to disrupt
ambient surface high pressure. Models and ensembles reasonably
agree that flow amplification then digs an energetic mid-upper
level trough across and to the north of the state this weekend.
This should force the front through the state by Sunday along with
an enhanced chance of showers. Moderate post-frontal high pressure
bridges to the north of the state next week in an emerging modest
trade flow pattern.
