Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 301 AM EDT Tue Sep 03 2024 Valid 00Z Wed Sep 04 2024 - 00Z Wed Sep 11 2024 High pressure northeast of Hawaii will support moderate to breezy trade winds through today before the high begins to retreat to the the northeast as a surface trough and cold front settles north of the islands. This will allow for a weakening of trade winds and some increased windward shower focus, though any rainfall should be light in nature given below normal precipitable water values. Upper ridging builds back by the weekend and lasting into early next week. Santorelli
