Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 309 AM EDT Mon Sep 02 2024 Valid 00Z Tue Sep 03 2024 - 00Z Tue Sep 10 2024 High pressure northeast of Hawaii will support moderate to breezy trade winds through about Tuesday 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 later next week and into the weekend. Santorelli
