Detailed Forecast
Synopsis
Strong trade winds will persist into next week, bringing brief showers to windward and mauka areas. Fewer leeward clouds are expected over the weekend, while the Kona slopes will receive their typical summertime afternoon/evening clouds and showers.
Discussion
A westward-moving mid-level trough at 700 mb will continue to enhance windward and mauka low clouds and showers this morning. Guidance continues to show the trough dissipating tonight into Saturday. Breezy to locally windy trades will prevail into next week as the surface ridge remains far north of the islands. ENE trade winds will deliver low clouds and brief showers to windward and mauka areas through the forecast period as the atmosphere stabilizes. Leeward areas will remain mostly dry, but Kona slopes of the Big Island will see their typical summertime afternoon and evening clouds and showers. May see an uptick in windward clouds and showers late next week as a weak upper level disturbance develops north of the state.
Aviation
A weak disturbance moving through the islands will enhance low clouds, and windward showers. Breezy to locally windy trades will continue for the next few of days, with passing showers favoring windward and mountain areas. Mostly VFR conditions will prevail, with brief periods of MVFR in showers/low clouds mainly in the overnight to early morning hours.
AIRMET Sierra for tempo mountain obscuration remains in effect for north through east sections of Kauai, Oahu, Molokai, Maui and the Big Island. These low cloud ceilings will improve later this morning.
AIRMET Tango for low-level turbulence over and in the lee of island terrain will remain in effect for the next several days due to the strong trades.
Marine
Strong- to near gale-force east to northeast trades with seas up to the 10 ft advisory level will continue through early next week as the ridge holds strong to the north. The strong trades could ease slightly later next week as the ridge weakens.
Surf along east facing shores will remain rough through early next week due to the strong trades locally and upstream of the state. A downward trend is possible around midweek as the upstream fetch weakens and the local trades begin to ease.
Surf along south facing shores will remain up as overlapping south-southwest swells move through. A fresh south-southwest that has filled in will result in an gradually upward trend through Saturday. A more significant south swell will gradually fill in late Saturday night into Sunday, then likely reach the advisory level late Sunday through Monday. A gradual downward trend is expected Tuesday through midweek.
