Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 821 AM EDT Thu Sep 22 2016 Valid 00Z Fri Sep 23 2016 - 00Z Fri Sep 30 2016 Models and ensembles reasonably agree that surface ridging to the north of the state today will remain supportive of a near moderate trade flow pattern over the islands, albeit with limited moisture and windward showers. Deeper tropical moisture should fuel more widespread showers Thursday through Saturday. Mid-upper level trough passage to the north of the islands may relax island trades over the weekend as an attendant front with pooled moisture and convection holds well north of the state. Drier island trades may rebound up to moderate to locally brisk levels next week in the wake of system passage as high pressure builds to the north of the state. Kocin
