Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 830 AM EDT Wed Jul 13 2016 Valid 00Z Thu Jul 14 2016 - 00Z Thu Jul 21 2016 The longwave pattern remains retrogressive through early next week with stronger upper level confluence contributing to a stronger and broader surface high and therefore the potential for stronger trades by this weekend. The primary potential impacts the next week will be following Celia which is projected to track north of the islands by next Monday with the 00z ecmwf closer to the official NHC track versus the 00-06z gfs which are to the south, and then Darby possibly moving close to the islands by next Wednesday with the gfs and ecmwf nearly identical. Refer to the NHC for the official forecasts of these systems. James
