Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 731 AM EST Fri Nov 18 2016 Valid 00Z Sat Nov 19 2016 - 00Z Sat Nov 26 2016 Trades will remain moderate to strong at times through the next week as strong high pressure and its surrounding tight pressure gradient are continually reinforced by regenerated upper level confluent flow northeast of the islands...with next Tuesday and Wednesday possibly associated with the strongest winds. Model agreement is quite good overall...with a mean longwave trough extended across the eastern Pacific and a mean longwave ridge north of the islands. Rain chances will remain about normal until early next week when guidance allows higher moisture values to reach the area. James
