Detailed Forecast

Synopsis

Moderate and breezy trade winds will continue, with clouds and showers favoring windward and mauka locations as areas of moisture move through. Expect some showers to carry over into our leeward areas periodically through the weekend due to an upper disturbance in the area. A drier trade wind pattern is expected next week as the upper disturbance lifts away to the north.

Discussion

A showery trade wind pattern is anticipated through the holiday weekend due to a weak mid- to upper-level trough moving through the area. The overnight soundings at Hilo and Lihue showed weaker/elevated trade wind inversions with a sufficient amount of low-level moisture (PWs around 1.18-1.34 inches) in place. This environment combined with the breezy trades and areas of moisture moving through will support decent windward shower coverage, with some holding together into leeward areas of the smaller islands. Although confidence is low, trades could ease slightly this evening into the weekend for the western end of the state due to a combo of the upper trough in the area and the ridge weakening to the north.
For next week, guidance depicts the aforementioned upper trough lifting northward and away from the state. This will translate to a more stable trade wind pattern with less windward shower coverage each day.

Aviation

Moderate to locally breezy trade winds will continue to push patches of stable and showery low clouds over the islands from the E, leading to periods of MVFR VIS/CIG, mainly over windward areas. A nearby low aloft will continue to slightly destabilize the island atmosphere, with radar detecting a few heavy rain cores, with some cloud tops extending as high as 12 kft. Shower coverage will be sufficiently great at time to warrant AIRMET Sierra for windward slopes of most islands at times through tonight.

Marine

The pressure gradient back across the islands from surface high pressure centered far north to northeast of the state will maintain fresh to locally strong trade winds over both the local nearshore and offshore waters the next several days. The Small Craft Advisory remains in effect for the winder areas surrounding Maui County and Big Island through Saturday afternoon but will likely need to be extended even further in time.
The offshore northwest buoys are picking up on longer period energy from the next west northwest swell that will be arriving and slowly building over the more western islands through Saturday. This small, medium period swell will peak surf along the north and west facing shores of Kauai later this afternoon and Oahu on Saturday. A slightly larger reinforcing west northwest swell will fill in late Saturday into early Sunday. This swell will likely push higher sets to around head high along various north and west facing shores Sunday afternoon and evening. South facing shore surf will remain low today with only a small background southerly swell. The weekend arrival of a slightly higher, longer period southwest south swell will provide a slight boost to surf along southern exposures from this weekend through the middle of next week. Moderate to fresh trades will continue to generate rough, choppy surf along eastern facing shores. East shores that have some southern exposure may experience slightly higher waves from south swell wrap.
