Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 320 AM EDT Tue Jun 29 2021 Valid 00Z Wed Jun 30 2021 - 00Z Wed Jul 07 2021 Model guidance continues to show excellent agreement for a gradual increase of the trade winds through this week and into the July 4th weekend. A front/shearline initially stalled over the Papahanaumokuakea National Marine Monument will gradually disintegrate before a subtropical ridge to the northeast of Hawaii strengthens and expands westward while surface pressure decreases across the equatorial central Pacific. This pattern will allow the trade winds to progressively increase to moderate levels across Hawaii and renew windward terrain/mountain focusing showers through the weekend and into early next week.
