Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 308 AM EDT Sun May 30 2021 Valid 00Z Mon May 31 2021 - 00Z Mon Jun 07 2021 Southerly winds ahead of a cold front well to the north of Hawaii should shift back easterly by the early to middle part of the week as high pressure builds north of the islands. This general pattern is forecast to hold all the way through next weekend with moderate to locally breezy trade winds. This would support stable and dry conditions across Hawaii for the next week, with scattered sea breeze driven afternoon showers tending to favor the leeward and interior sections. The latest models and ensembles all show very good agreement on this overall large scale pattern. Santorelli
