Detailed Forecast
Synopsis
Moderate trades will focus low clouds and showers over windward and mauka areas into next week, especially overnight and during the early morning.
Discussion
Typical, quiet summertime trade wind pattern prevails over the islands through the forecast period. Moderate trades will continue into next week bringing pockets of low clouds and showers to windward and mauka slopes, mainly overnight and during the early morning. Weak troughing embedded in the trades is modeled to advance over the western half of the chain during the latter half of the weekend. The antecedent subsidence inversion will represent a hostile environment for meaningful expansion of showers during this time, particularly during peak heating. Nonetheless, a slight upward tug on the existing inversion may allow a few additional showers into leeward portions of Oahu and Kauai during the day Sunday. Otherwise, little to no change expected during the next several days. The subtropical jet will continue to be a source of periodic high clouds.
Aviation
A high pressure ridge will remain far north of the islands this weekend producing moderate trade winds. Expect passing showers with brief periods of MVFR conditions lasting through Sunday favoring the overnight to early morning hours.
No AIRMETs in effect.
Marine
A ridge of high pressure far north of the state will maintain moderate trade winds through the weekend. Seas remain well below average for Hawaii standards with nearshore buoys around the islands reporting significant wave heights of 4 feet or less. Climatology plots from CDIP show some of the south facing buoys such as Barbers and Lanai buoys near record low for this time of year. Trades winds will begin to gradually strengthen late Sunday into the first half of next week as the ridge north of the area strengthens. Locally strong trade winds for the windier waters around Maui County and the Big Island will likely return around Monday of next week.
No significant swells are expected along all shores through next week. For south facing shores, only background swells are expected through most of next week. A low pressure currently far southeast of New Zealand will likely produce a small south swell for next weekend. East shore surf will remain small through the weekend, then gradually trend upward next week as trade winds increase.
