Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 815 AM EDT Tue Apr 02 2019 Valid 00Z Wed Apr 03 2019 - 00Z Wed Apr 10 2019 Models and ensembles agree to develop modest trades over the next few days as supporting post-frontal high pressure bridges just to the north of the state in a drier air mass with limited moisture and showers. An approaching cold front may act to weaken trades heading into this weekend as the surface high shifts eastward into the subtropical northeast Pacific. Expect gradually increasing shower activity over the weekend into early next week as lead return flow brings increasing deep moisture from the southeast behind the departing subtropical surface anticyclone. Forecast spread and uncertainty with embedded weather feature specifics increases more substantially at longer time frames, but a favored guidance composite suggests that trades may also return to seasonal levels early next week as high pressure rebuilds to the north of the state in the wake of the stalling front. This offers potential for enhanced windward terrain precipitation. Schichtel
