Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 724 AM EST Tue Jan 01 2019 Valid 00Z Wed Jan 02 2019 - 00Z Wed Jan 09 2019 Models and ensembles continue to show excellent agreement that Hawaii will remain under the influence of the subtropical ridge through early next week. An upper-level low is forecast to remain stationary well to the east of Hawaii and should have little to no impact on the local weather in Hawaii. Other than some terrain-induced showers, relatively dry conditions will prevail through early next week under fresh to strong easterly winds as a couple of surface high pressure systems continue to supply dry air from higher latitudes. Winds should be the strongest on Friday and Saturday as the second high pressure center passes by to the north but they should moderate by early next week as a cold front attempts to move toward the state from the mid-latitudes.
