Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 829 AM EDT Wed Jun 25 2014 Valid 00Z Thu Jun 26 2014 - 00Z Thu Jul 03 2014 The prevailing pattern across Hawaii shows a weakness in the upper high presently northwest of the islands drifting eastward while slowly modulating...although its weakness appears to have minimal influence regarding sensible weather. The 00z ecmwf is stronger and less preferred with an amplifying shortwave trough north of the islands by next Monday compared to the more preferred and flatter 00z gfs but again makes little difference. Generally divergent lower level flow will prevail during the next 7 days with only minimal chances of rainfall...mainly scattered and diurnally-driven while moderate trades persist. The solution spread is about average for this pattern with near to perhaps slightly above average forecast confidence. James
