Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 808 AM EDT Wed Jun 17 2015 Valid 00Z Thu Jun 18 2015 - 00Z Thu Jun 25 2015 Ensembles continue to show a rather quiet pattern in store over Hawai'i for the next week. Good agreement among the guidance shows upper ridging and surface high pressure building to the northwest of the 50th state later this week into the weekend. This will keep fresh trades in place with a slight increase in moisture expected on Sunday especially in the northwestern islands as it rotates around the upper high. Otherwise, isolated to scattered windward showers are expected with generally light amounts except in higher elevations. Fracasso
