547 FXHW01 KWNH 120800 PMDHI Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 300 AM EST Tue Nov 12 2024 Valid 00Z Wed Nov 13 2024 - 00Z Wed Nov 20 2024 Latest model guidance is very agreeable that an upper level ridge and mean surface high pressure should prevail for much of the next week over/north of Hawaii. This will maintain brisk to strong easterly trade winds, with gradually increasing speeds through the week and lasting into next weekend as strong high pressure settles northeast of the state. 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/next weekend. An upper low well north of Hawaii looks to push upper riding eastward in about a weeks time, allowing for weaker trades by early next week. Santorelli $$
