Area forecast discussion, Jun 30, 8:56 PM HST, 3 hours 4 minutes before
Area Forecast Discussion National Weather Service Honolulu HI 856 PM HST Fri Jun 30 2023 .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 moderate trade wind pattern will hold through the weekend. No marine hazards are expected through the weekend. Trades winds will trend up Sunday as the ridge north of the area strengthens, becoming locally strong and holding into next week. Small Craft Advisories (SCA) for the typically windier channels will likely become necessary at that time. 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. && .HFO WATCHES/WARNINGS/ADVISORIES... None. && DISCUSSION...JVC AVIATION...Bohlin MARINE...Kino
