Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 729 AM EST Mon Dec 03 2018 Valid 00Z Tue Dec 04 2018 - 00Z Tue Dec 11 2018 Post-frontal high pressure settling north of the state should support modest trade return through midweek as residual moisture pooled along the stalled frontal lingers near the state. Residual moisture over the next few days is expected to fuel additional showers, especially for the southern islands. Amplified mid-upper level trough approach from the northwest Thursday should force another moisture/shower enhancing front into the islands late week as energy digs to the lee of a building mid-upper level ridge upstream over the subtropical west-central Pacific. Guidance remains reasonably clustered so prefer a composite solution. Schichtel
