Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 259 AM EST Sun Nov 10 2024 Valid 00Z Mon Nov 11 2024 - 00Z Mon Nov 18 2024 Latest model guidance is very agreeable that an upper level ridge and mean surface high pressure should prevail for the next week over/north of Hawaii. This will maintain brisk to strong easterly trade winds, with gradually increasing speeds through the week as strong high pressure settles northeast of the state by next weekend. Showers should focus primarily over windward/mountain locations, with increasing moisture leading to some heavier showers along eastern slopes of the southernmost islands later in the week. Santorelli
