Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 812 AM EDT Wed Jul 25 2018 Valid 00Z Thu Jul 26 2018 - 00Z Thu Aug 02 2018 Moderate trade winds can be expected through the next week with surface high pressure remaining north and northeast of the state. Multiple easterly waves will move westward south of islands, with each wave bringing a modest enhancement to low-level easterly flow. The first of these will focus showers across, but not fully limited to windward terrain through into Thu. A second wave is expected to pass well south of Hawaii Fri-Sat, with drier air advecting across the state in its wake. Another period of enhanced shower activity is possible with yet another wave by the middle of next week, especially over the Big Island. Ryan
