Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 723 AM EDT Fri Jun 03 2016 Valid 00Z Sat Jun 04 2016 - 00Z Sat Jun 11 2016 The 3/00Z ECMWF and GFS and their ensemble means were reasonably 'synched' with the Pacific Basin flow pattern and current 7-day Hawai'i forecast. The primary sensible weather features during the next 48 to 72 hours will be tied to a slow-moving mid-latitude long wave trough and mid-level low. This trough (currently near 155W longitude) will press slowly eastward to ~145W by late Sunday evening (HST) --- 6/12Z. A mid-level southwest flow---with origins in the Equatorial central Pacific should add additional cyclonic flow and moisture to the base of the trough. Behind the trough, strong deep-layered ridging should migrate eastward early next week---extending across much of the Subtropical Pacific. This deep-layered ridge is expected to generate a moderate to brisk statewide tradewind pattern. Vojtesak
