Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 814 AM EDT Tue Aug 08 2017 Valid 00Z Wed Aug 09 2017 - 00Z Wed Aug 16 2017 Ensembles show good agreement with a building closed upper and surface high to the north of the area later this week. This will support increased trades late Thursday through the weekend. Hawai'i should be caught in between deep tropical moisture along the ITCZ and moisture flowing around the high to the north, which supports a relatively dry period. Mainly isolated to scattered windward/mauka showers are expected which may spill over to leeward areas due to the breezy trades. A weakness aloft may try to push westward past 150W by next Tuesday.
