Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 730 AM EST Mon Nov 19 2018 Valid 00Z Tue Nov 20 2018 - 00Z Tue Nov 27 2018 Models and ensembles show excellent agreement on the synoptic pattern that will affect Hawaii throughout this week into the weekend. Fresh to strong trade winds should prevail through the middle of the week as a subtropical high passes well to the north. By the end of the week, winds should turn more easterly and gradually weaken as the subtropical high departs. By the weekend, models show the approach of a cold front from the mid-latitudes but it appears that it will stay enough to the north of the islands. Expect typical terrain-enhanced showery weather to continue through the end of the week with light winds during the weekend into Monday. Kong
