Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 651 AM EST Sun Dec 31 2017 Valid 00Z Mon Jan 01 2018 - 00Z Mon Jan 08 2018 Quiet pattern for Hawai'i over the next week as lower than average atmospheric moisture supports only isolated to maybe scattered light windward showers. Upper heights will build from the west across the Aloha state as a couple of successive surface highs move eastward along 33N. Trades will be breezy from time to time especially by the weekend due to the strengthening pressure gradient as a 1024-1027mb high dips to near 30N/150W. Fracasso
