Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 326 AM EDT Wed Jun 30 2021 Valid 00Z Thu Jul 01 2021 - 00Z Thu Jul 08 2021 Model guidance continues to show excellent agreement for a gradual increase of the trade winds for the remainder of this week and into the July 4th weekend. A front/shearline will continue to gradually dissipate over the Papahanaumokuakea National Marine Monument. A subtropical ridge to the northeast of Hawaii is forecast to strengthen and expand westward as 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/middle of part of next week.
