Hawaii Extended Forecast Discussion NWS Weather Prediction Center College Park MD 329 AM EDT Wed Jul 10 2024 Valid 00Z Thu Jul 11 2024 - 00Z Thu Jul 18 2024 A Pacific surface high to the north of Hawaii will strengthen through the latter part of the week, staying strong into early next week. This will promote breezy to windy easterly trades across the state for the next several days. Aloft, a mid-upper ridge is in place, suppressing notable rainfall. A weak mid-upper trough is forecast to move westward across Hawaii on the south side of the ridge Thursday-Friday, which could allow for a brief increase in shower coverage favoring windward/mauka areas. Then overall a dry pattern is likely late week into the first half of next week, with just a few windward/mauka showers in the breezy trades pattern. Tate
